ENVIRONMENTALLY FRIENDLY
C O O L I N G T E C H N O LO GY
Everyone talks about the future, but Rittal helps shape it – and that includes the field of climate control. Development work focuses on sustainability and environmental protection, and Rittal has always set special standards in
this field.
Pro Ozone, the symbol for eco-friendly cooling technology, has gained international renown since 1992. At that
time, attention focussed on replacing the coolant CFC, which was blamed for destroying the ozone layer, a vitally
important UV filter. Now, efforts are directed at the greenhouse effect. CO2 is the coolant of the future. For Rittal, it
is obvious that we need to act promptly to provide a functionally reliable yet powerful technology.
We smoothe the way for reliable investments, a healthy environment, and enhanced competitiveness for
our customers.
20
For those who place their trust in Rittal, value-added comes
as standard. What is more, Rittal is global trendsetter in the
field of climate control.
Setting trends means understanding our customers. This is
the pre-requisite for transforming our inventions into marketable innovations.
Three pioneering new features bear witness to this fact: Rittal
TopTherm cooling units are now equipped as standard with
innovative RiNano coating and integral electronic condensate evaporation, and CO2 as a refrigerant for cooling
units has achieved outstanding results in practical trials.

Rittal underscores its technological leadership in the field of CO2
climate control. Compared with
CO2, as a component of the
atmosphere, the refrigerant R134a
has a direct greenhouse effect that
is 1300 times more powerful.
Any condensate incurred is effectively evaporated and doesn't
need to be collected or dissipated.
Following the example of the lotus
flower, the ultra-thin, glass-like RiNano
sealing of the heat exchanger membranes prevents dirt particles from
adhering to the condenser.
Rittal has achieved huge success
with the use of CO2 as a coolant.
The first prototypes were unveiled
back in 2005.
In 2006 Rittal launched a series of
CO2 cooling units that had undergone extensive practical trials.
Your value-added:
● Enhanced safety – No dripping
condensation
● Time savings – No need to
empty condensate containers
● Cost benefits – No need to lay

Basic principles of climate
control components
Guide to selecting suitable units.
1.1
As electronic components become ever smaller and are
more densely packed in enclosures and electronic cases,
systems are becoming increasingly sensitive to external factors such as dust, oil, moisture and temperature.
Heat in particular is a deadly enemy of sensitive microelectronics.
For example, a general rule of thumb for semi-conductors is that an increase in the operating temperature of
10°C, in relation to the maximum permissible operating
temperature, will shorten its service life by one-half.
In order to guarantee proper functioning of the electronics,
this heat needs to be dissipated.
Ambient
conditions
Heat conduction
Enclosure interior
problems
Convection
Radiation
There are three basic forms of heat transfer:
Thermal conduction:
Heat is transported by matter, without the matter itself being
moved. The energy is passed from particle to particle.
Heat
Heat loss
Convection:
Energy flows with the matter. The transport medium, e. g. a
liquid or gas, takes up energy in the form of heat and dissipates energy as heat.
Radiation:
Heat is passed from one body to another in the form of radiation energy, without a medium material.
Dust
Condensate
The decisive factor for the type of heat dissipation to be used
in enclosures is whether they are open (air-permeable) or
closed (air-tight). Whereas in open enclosures, the heat is
dissipated by means of air circulation, in closed enclosures
the heat can only be dissipated via the enclosure wall.
Rittal cooling units provide the ideal solution for ensuring an
optimum operating temperature inside an air-tight enclosure,
even at high external temperatures.

The following pages contain detailed calculation formulae for your chosen option.
Calculation of effective enclosure surface area
Of the variables required for calculation purposes, the effective enclosure surface area A requires special explanation.
The thermal output dissipated by the enclosure not only
depends on its actual surface area; the installation type of
the enclosure also plays a decisive role.
An enclosure which stands in a room unobstructed on all
sides may dissipate more heat than one sited against a wall
or in a niche. For this reason, there are precise specifications on how to calculate the effective enclosure surface area
depending on the type of installation site. The formulae for
calculating A are specified in DIN 57 660, part 500 and
IEC 890 (see table below).

General information
Calculation bases for enclosure climate
control
3.1
In natural convection, heat loss is dissipated to the outside
via the enclosure panels. The pre-requisite for this is that the
ambient temperature must be lower than the temperature
inside the enclosure. The maximum temperature increase
(ΔT)max. which may occur inside an enclosure compared with
the ambient air is calculated as follows:
.
Qv
(ΔT)max. =
kA
.
Qv = Heat loss installed in the enclosure [W]
.
Qs = Heat
emitted by the enclosure surface [W]
.
Q. s > 0: Radiation (TI > TU)
Qs < 0: Irradiation (TI < TU)
.
QK = Required cooling output of an enclosure cooling unit [W]
.
QH = Required thermal output of an enclosure heater [W]
qw = Specific thermal output of a heat exchanger [W/K]
.
V = Required volumetric air flow of a fan-and-filter unit to maintain the maximum permissible temperature difference
between the extracted air and the emitted air [m3/h]
ΔT = TI – TU = Max. admissible temperature difference [K]
Note:
If the heat loss inside the enclosure is not known, this basic
formula can be used to calculate actual heat loss, by measuring the ambient temperature TU and the enclosure internal
temperature TI:
A = Effective, heat loss-dissipating enclosure surface area to
IEC 890 [m2]

Condensation and dehumidification of enclosure air
when using cooling units
One unavoidable side-effect of using cooling units is the
dehumidification of the enclosure’s interior air. As it cools
down, part of the humidity contained in the air condenses on
the evaporator coil. This condensate must be reliably discharged from the enclosure. The amount of condensate
occurring depends on relative humidity, the air temperature
inside the enclosure and on the evaporator coil, and the air
volume present in the enclosure. The Mollier h-x diagram
shows the water content of air depending on its temperature
and relative air humidity.

Practical tips
In all situations where optimum operating temperatures are
required inside an enclosure, even at high external temperatures, a Rittal enclosure cooling unit can provide the right
solution. It is even possible to cool the interior temperature of
the enclosure to well below the ambient temperature.
The favourable aerodynamic arrangement of the air inlet and
outlet openings in the internal and external circuits ensures
optimum air circulation inside the enclosure. This sample calculation will show you a quick, time-saving method for calculating a cooling unit.
The quantity of condensation is calculated from the following
equation:
Example:
An enclosure cooling unit commences operation with a temperature setting of Ti = 35°C.
The relative ambient air humidity is 70%. If air at 35°C is
passed over the evaporator coil, the surface temperature of
the evaporator coil (evaporation temperature of the refrigerant) is approximately 18°C.
At the boundary layer adhering to the surface of the evaporator coil, water is deposited at the dew point. The difference
Δx = x1 – x2 indicates how much condensation is incurred per
kg of air with complete dehumidification. The leak-tightness
of the enclosure has a decisive effect on the quantity of condensation.

Only the enclosure volume is dehumidified.

= 0.6 m3 1.2 kg/m3 11 g/kg
W = 7.92 g ^ 8 ml
Poorly sealed cable designs, damaged door seals and the
attachment of display media to enclosure surfaces lead to
increased rates of leakage in the enclosure. Hence, with a
leakage rate of, say, 5 m3/h, a continuous condensate volume of up to 80 ml/h may occur.
Summary:
Enclosure cooling units should only operate with the door
closed.

Recooling systems
Recooling systems
Recooling systems may be used in all situations where a high
cooling load is required, e.g. in process and machine cooling, in media cooling or when dissipating heat loss from
enclosures via air/water heat exchangers.
Our project engineers will be happy to help you design a
recooling system for your specific application area. An overview of the planning data required for this purpose can also
be found on the Internet at www.rittal.com in the section on
system climate control/recooling systems.

Project planning examples of recooling systems may be
found in Catalogue 31, page 606/607.
Cooling water
Preparation and maintenance of the water in recooling
systems
Depending on the type of installation to be cooled, certain
requirements are placed on the cooling water with respect to
purity. According to the level of contamination and the size
and design of the recooling systems, a suitable process is
used to prepare and/or maintain the water.
The most common types of contamination and most frequently used techniques to eliminate them in industrial cooling are:
Contamination of the water
Mechanical contamination
Excessive hardness
Moderate content of mechanical
contaminants and hardeners
Moderate content of chemical
contaminants
Biological contaminants, slime
bacteria and algae
Procedure
Filtering of water via
– Mesh filter
– Gravel filter
– Cartridge filter
– Precoated filter
Water softening
via ion exchange
Addition of stabilisers and/or dispersing agents to the water
Addition of passifiers and/or inhibitors to the water
Addition of biocides to the water

Notes on water quality
For safe operation of the equipment, it is essential to observe
the VBG guidelines on cooling water (VGB R 455 P).
Cooling water must not contain any limescale deposits or
loose debris; in other words, it should have a low level of
hardness, particularly a low level of carbon hardness. For
recooling within the plant, the carbon hardness should not be
too high. On the other hand, however, the water should not
be so soft that it attacks the operating materials. When
recooling the cooling water, the salt content should not be
allowed to increase excessively due to the evaporation of
large quantities of water, since electrical conductivity
increases as the concentration of dissolved substances
rises, and the water thereby becomes more corrosive. For
this reason, not only is it always necessary to add a corresponding quantity of fresh water, but also to remove part of
the enriched water.
Gypsiferous water is unsuitable for cooling purposes
because it has a tendency to form boiler scale, which is particularly difficult to remove. Furthermore, cooling water
should be free from iron and manganese, because otherwise deposits may occur which settle in the pipes and block
them. At best, organic substances should only be present in
small quantities, because otherwise sludge deposits and
microbiological contamination may occur.

Cooling units keep the enclosure internal temperature
at a constant level, even to below room temperature.
The air routing meets individual requirements. Two
separate circuits prevent the ingress of dust into the
enclosure.

● Climate controlled enclosures
● Roof-mounted cooling units

4.1
Integral cooling system/climate controlled
enclosures
The combination of enclosure and cooling components
achieves particularly effective cooling. Assembly time is eliminated. The investment costs for the complete unit offer
exceptional value for money.
Roof-mounted cooling units
Requirement-oriented routing of cooling air in the internal
circuit is possible, with up to four cold air outlet openings and
the optional use of ducts. In the external circuit, the heated
air is expelled to the rear, left and right, and optionally
upwards. This means that the enclosure may be sited in a
bayed suite or close to the wall.
Wall-mounted cooling units
Depending on the space and design requirements, internal
mounting, partial internal mounting and external mounting
are all possible. Thanks to large distances between the air
intake and outlet openings, effective cold air throughput of
the enclosure is achieved.
32
Rittal System Climate Control
Cooling units
Selection criteria
Enclosure climate control poses escalating demands on integration and adaptation to the local conditions and the existing process control and monitoring system. Rittal offers the
right solution to suit every requirement.
When selecting the appropriate cooling unit for your enclosure, please observe the following points:
● What is the installation type to IEC 890?
(see page 27, calculation bases)
● What ambient conditions are anticipated (ambient temperature and humidity)?
● What is the required maximum internal temperature of the
enclosure (Ti)?
● What is the heat loss from electronic components inside
the enclosure?
● Is there a requirement regarding the protection category to
EN 60 529/IEC 529?
● What type of ambient pollution, such as dust, oil and
chemicals, are the cooling units exposed to?
● For bayed enclosure suites, the output irradiated from
neighbouring units may also need to be taken into
account.
● Good ventilation should be ensured at the site of installation (for example, the heat dissipated by the cooling unit
may cause a significant rise in the temperature of small
rooms).
● Particularly with poor ambient conditions, such as dirt or
small rooms, air/water heat exchangers should be used.
4.2
Important
Proper use of enclosure cooling units
In order to ensure the proper use of enclosure cooling units, the following points should be observed:
1. The unit must only be installed and opened by authorised,
expertly trained personnel.
2. Choose a location for the cooling unit which ensures excellent
ventilation. The site must be free from excessive contamination
and moisture. For example, the atmosphere must not contain
any conductive dusts or corrosive media.
3. The mains connection data (connection voltage and frequency)
specified on the rating plate must be observed. In the case of
400 V, 2~ cooling units, we recommend the use of transformer
circuit-breakers, and for three-phase units, the use of motor
circuit-breakers is advisable.
4. The prescribed electrical protection devices must be connected upstream of the unit. No additional temperature control
must be connected upstream of the device at the supply end.
The pre-fuse specified on the rating plate should be provided
as line protection. Observe the locally valid regulations when
installing.
5. Where a door contact switch is used, a shielded cable should
be used in environments with increased levels of electromagnetic interference.
Rittal System Climate Control
6. The temperature range specified on the rating plate must be
observed when operating the cooling unit, both indoors and
outdoors.
7. The enclosure must be sealed on all sides (IP 54).
8. The air inlet and outlet openings in the internal circuit of the
cooling unit must not be obstructed.
9. The cold air flow should not be directed straight at electronic
components, to prevent the formation of condensation.
10. The unit must only be installed horizontally, in accordance with
the prescribed installation position. The maximum permissible
deviation from the horizontal is 2˚.
11. After disconnecting from the supply voltage, the cooling circuit
of the cooling unit must not be switched back on for at least
5 minutes.
12. The customer must not make any modifications to the cooling
unit.
13. The heat loss of the components installed in the enclosure must
not exceed the specific useful cooling output of the cooling unit.
14. The installation instructions contained in the cooling unit manual must be observed in full.
33
Cooling units
Assembly
Sealing of the enclosure
The enclosure must be sealed on all sides (IP 54). Particular
attention should be paid to the sealing of the area around the
cable entry openings and above all, the floor section of the
enclosure.
Additionally, the door seal must be in perfect condition.
The sealing material included with the cooling units must be
applied in accordance with the installation instructions.
Take care not to bend the side panel or enclosure door.
4.3
Installation on enclosures
The cooling unit must be correctly installed.
The roof plate of the enclosure must not be allowed to give
under the weight of the cooling unit.
If necessary, additional stays should be used. Do not
obstruct the air inlets and outlets of the internal circuit.
Note:
For TopTherm roof-mounted units, TS 8 roof plates prepared
with mounting cut-outs and reinforcement strips for all standard enclosure sizes are available as an accessory (Cat. 31,
page 664).
When installing after the unit has been assembled, the twinthreaded bolts supplied loose should be screwed into the
core holes in the plastic base on the underside of the device,
with a maximum torque of 3 Nm.
34
Rittal System Climate Control
Cooling units
Air routing
External circuit
Flow and siting conditions
In the outer circuit, enclosure cooling units should be spaced
200 – 400 mm from the wall and/or from each other (air inlet
and outlet openings). In order to ensure adequate air circulation, at least one air outlet opening must be kept free.
If this clearance cannot be maintained, air baffle plates will
need to be used.
The external circuit supports all siting variants.
Thanks to their compact dimensions and external air routing
design, roof-mounted cooling units may even be installed in
low-height rooms and with bayed enclosure suites.
Air intake is always from the front. The air is expelled at the
sides and rear. An outlet to the top is also possible as an
option. In other words, regardless of which siting mode is
chosen, one air outlet must always be kept free.
Distance from the wall
at least 200 – 400 mm
Siting options
There are no restrictions here. Only the air intake and exhaust
area in front of the cooling unit must be kept free.
Wall-mounted cooling units may be mounted on the rear
panel, side panels or door of the enclosure.
4.4
Internal circuit – Wall-mounted units,
flow conditions
Attention should be paid to components/electronic components equipped with their own ventilation systems, such as
blowers and axial fans. If their air flow is directed against the
chilled air flow of the cooling unit, this could cause an air
short-circuit and prevent adequate climate control. In the
worst case, this air short-circuit could reach the cooling unit
itself, and the internal safety valves would discontinue cooling operation.
Note:
Never direct the chilled air flow at active components.
Accessories:
Air diverter, see Cat. 31, page 659.

Cooling units
Air routing
Free air circulation
200
It is important to ensure “even” air circulation inside the
enclosure. Air inlet and outlet openings in the internal circuit
must on no account be obstructed by electrical installations.
This would prevent air from circulating inside the enclosure.
Under such conditions, the cooling capacity of the device
would not be adequately utilised. A clearance of > 200 mm
must be guaranteed.
Note:
Wall-mounted cooling units should never be fitted directly
behind the mounting plate. Active power components are
located on the front of the mounting plates. The cooling unit
would then be left to operate in its own air short-circuit.
If it is impossible to install the device any other way, appropriate air baffle plates should be used, and air inlet and outlet
openings should be provided in the mounting plate.

Air routing
Air-ducting system
for TopTherm roof-mounted cooling units
With the air duct system, it is possible to route the cold air
directly to specific areas of the enclosure. This effectively
eliminates the risk of “short circuits” in the air circulation due
to self-ventilated components.
Note:
● Never direct the cold air flow straight at active components.
● Route the air duct system directly downwards with no
bends.
● Cold air must be able to escape unobstructed at the end of
the duct.
● Additional deflections will reduce the useful cooling output.
● When using the ducting system, the performance of the
cooling unit may be reduced, depending on the respective application.
● The air duct system should not be extended.

Any condensation which forms on the evaporator coil (with
high humidity and low enclosure interior temperatures) is
routed to the right and/or downwards out of the device via a
drain in the evaporator tray. For this purpose, a piece of hose
should be connected to one of the two condensate nozzles
(1 or 2). The drain which is not required should be tightly
sealed. The condensate must be able to run off freely. If
the condensate is to be drained off over a greater distance, then care must be taken that the hose is free from
kinks, and checked for correct drainage. Units with a Comfort controller are additionally equipped with a condensate
alarm.

Condensate evaporation, electrical
integrated into TopTherm cooling units
Condensate arising inside the enclosure or on the evaporator coil of the cooling unit is effectively evaporated. The evaporator device inside the cooling units has a very high evaporation output (several litres per day). This is achieved thanks
to the principle of direct evaporation. Important note: The
enclosure must be sealed on all sides.
Rittal ation
innov
Energy-efficient: Activation of the evaporator device is via a
separate heater cartridge. “Condensate evaporation” based
on the hot gas bypass principle is too ineffective, due to
inadequate evaporation temperatures.
Advantage:
● Safe use: No condensate drips onto the factory floor (no
puddles/no risks of slipping/accidents).
● No need to empty the condensate collecting receptacles.
● No time-consuming laying of condensate hoses required.
4.5
The internal and external units are acitve “direct evaporator
coils”, which actively evaporate the condensate incurred.
Advantage:
● No collecting vessel required
● No long hosepipes
Note:
For roof and wall-mounted units, either external evaporator
units or integral condensate evaporators may be used.
TopTherm cooling units are available with integrated electronic condensate evaporation and external evaporator units
for retro-fitting.
Filter mats
In dusty environments, we recommend the use of filter mats
to make it easier to clean the cooling unit.
The filter should be changed at regular intervals, depending
on the level of contamination.
If the air is oil-contaminated, it is better to use metal filter
mats which may be cleaned with appropriate detergents and
reused.

Use of door operated switches
One floating door-operated contact should be used for each

operated via one door operated switch.
In environments with increased electromagnetic interference, a shielded cable should be used.
Alternatively, the door contact may be switched e.g. via an
additional relay in the vicinity of the cooling unit.

Together with the seal, the lower
part of the two-part quickchange frame is screw-fastened
to the enclosure. This makes it
possible to mount the connectorready cooling unit onto the
enclosure and remove it from the

During servicing work, this
means shorter assembly times
and hence minimised downtime. What is more, the quickchange frame offers effective
protection against the ingress of
oil into the enclosure in oily
atmospheres, thanks to its integral drainage trough.
There are roof plates preequipped with a mounting cutout available to fit all standard
enclosure dimensions and cooling unit output categories. Manual machining of the mounting
cutouts has been eliminated
altogether.

This makes optimum allowance
for the available space conditions. The enclosure surface
containing the cut-out for partial
or full internal mounting is stabilised by the divided internal
case construction. Special internal or external mounting kits are
not required.

Recooling systems ensure centralised, efficient cooling and provision of the cooling medium (generally
water), and are used with particularly high heat loads.
They may serve several pieces of equipment simultaneously, and are particularly effective in terms of cool-

ing output.
5.1
Application diversity of centralised cooling technology
Enclosure cooling
In conjunction with air/water heat exchangers, optimum dissipation of high heat loads is guaranteed, even under extreme
ambient temperatures and air contamination levels.
Cooling of liquid media
The direct and indirect cooling of liquids is essential for
ensuring the required levels of machine accuracy and
speed.
Process cooling
High-quality material processing, such as laser cutting,
necessitates high levels of temperature precision with simultaneous cooling of the peripheral technology.

Rittal System Climate Control
Recooling systems
Selection criteria
Generally speaking, recooling systems are divided into open
and closed systems.
In the pressure-sealed configuration, the water circuit is
equipped with a pressure relief valve and automatic exhaust.
In this way, the cooling medium volume can be routed
directly to the consumer with the integral pump, and no additional tank reservoir is needed.
Recooling systems designed as an open system have a tank
made of PP plastic or stainless steel 1.4301 built into the
recooling system.
If a recooling system is required to serve several pieces of
equipment having different requirements in terms of inlet temperature and flow rate of the cooling medium, e.g. combined
enclosure and process cooling, multi-circuit systems are
used. In such cases, the different circuits may be tailored to
the respective equipment.
If there is already a central cooling water supply available at
the installation site, e.g. in the case of plant water in the automotive industry, recooling systems may optionally be fitted
with a water-cooled condenser. One of the major benefits of
this solution lies in the fact that the factory temperature is not
additionally raised by waste process heat.

High heat loads can even be dissipated in confined and awkward spaces, thanks to the spatial separation of the recooling system from the enclosures and machine. In all cases, as
well as enclosure cooling, cooling water may also be produced for process and machine cooling or for cooling liquid
media.
Recooling systems in floor-standing and industrial enclosures, with their robust design, are the ideal stand-alone

Outdoor siting
To avoid putting additional pressure on the factory air with
the waste heat incurred during the process, the recooling
system may be supplied with the option of outdoor siting (for
ambient temperatures up to –20°C).
In such cases, a rain canopy should be provided to protect
the recooling system from extreme weather. The water circuit
must be filled with 34 % anti-freeze agent Antifrogen N (or
equivalent) to 66 % water in relation to the total water volume.

Notes/benefits
Assembly and commissioning
In the case of air-cooled recooling systems, the following minimum distances from the wall and ceiling should be observed:
2
1
Recooling
system
1 Wall: At least 1x condenser height
2 Ceiling: At least 3x the condenser height
Distance from equipment
Site the recooling system
close to the equipment in
order to avoid long distances, which could lead to
performance losses. When
selecting the installation site,
care should be taken to
ensure easy access at all
times; this will make maintenance of the system easier.
You should also ensure adequate ventilation of the room
where the recooling system
is sited. If there is inadequate ventilation, the temperature of the room will
increase as a result of waste
heat, leading to impaired
performance of the recooling system.
When siting the recooling system, the following points
should be observed:
● Connection of an inlet and outlet duct shall require the
manufacturer's prior consent.
− Performance loss (air-cooled recooling system)
● Never site the recooling system in the vicinity of a heater.
− Performance loss
● The recooling system may only be sited on flat, solid surfaces. The maximum permissible deviation from the vertical is 2°.
● Connect the equipment to the recooling system using insulated pipe or hose connections.
● If the equipment is positioned higher than the recooling
system, install a non-return valve upstream in the inlet and
a magnetic valve in the return.
− To avoid overflowing the tank.
● With recooling systems that are intended for covered outdoor siting, the minimum external temperature is given in
the technical specifications.
● In the case of recooling systems (for water) at temperatures below zero, a water/glycol mixture should be added
in the prescribed ratio.
● If it is possible to shut off the equipment cycle, a bypass
must be provided in order to protect the pump.
● Under no circumstances must the circulation pump be
allowed to run dry.
− Damage to the pump

Cooling media
Apart from the recooling systems for oil and emulsion, all
other recooling systems are
only suitable for the cooling
of water or a water/glycol
mixture. When filling the systems for the first time, water
from the existing supply line
is generally suitable,
although care should be
taken to ensure a consistent
water quality.
However, as satisfactory
results are only rarely
achieved without water treatment, additives should
always be added to the cooling water, irrespective of the
installation site. As well as

protecting against frost,
these also serve to impair
bacterial growth and achieve
optimum corrosion protection.

Air/water
heat exchangers
Applications
Ambient conditions
Air/water heat exchangers effectively dissipate high
heat losses. Thanks to the spatial separation of the
heat exchanger and recooling system, the room is not
burdened with waste heat.
Heat
Dust
Ideal at any installation site
6.1
High ambient temperatures and extreme levels of contamination are ideal conditions for the use of air/water heat
exchangers. If direct dissipation of heat loss to the ambient
air is undesirable or ineffective due to the confined space,
the air/water heat exchanger may likewise offer an ideal solution. Very effective cooling solutions for individual enclosures
or bayed enclosure suites may be achieved by separating
the exchanger from the recooling system.
Practical example of an air/water heat
exchanger
In such situations, low-maintenance air/water heat exchangers are used as efficient all-rounders. Either fed from existing
cooling water networks or from separate recooling systems,
these products contribute to an ideal climate inside the
enclosure. The cooling water absorbs the heat inside the
heat exchanger and conveys it to the corresponding cooling
system. In this way, even small rooms are exempt from additional waste heat from the enclosure, and the electronics
inside the enclosure are effectively protected.

In all areas with extreme ambient conditions, enclosure and

51
Air/water heat exchangers
Assembly
Application benefits
Compact and lightweight
Air/water heat exchangers have a low weight and a comparatively low volume in relation to the heat loss dissipated. As a
result, they are easily mounted on vertical enclosure surfaces or on the roof.
Air/water heat exchanger integrated into the side panel
The side panel combines effective heat dissipation with minimum space requirements. It may be used in all 600 mm
deep, 1800 mm/2000 mm high TS 8 enclosures.
Virtually maintenance-free
Because the ingress of ambient air into the heat exchanger is
prevented, dirt is unable to penetrate. Control of the air and
water circuit is electronically monitored.
Sealing of the enclosure
6.3
The enclosure must be sealed on all sides (IP 54). Particular
attention should be paid to the sealing of the area around the
cable entry openings and above all, the floor section of the
enclosure.
Additionally, the door seal must be in perfect condition.
The sealing material enclosed with the heat exchangers must
be applied in accordance with the installation instructions.
Take care not to bend the side panel or enclosure door.
Installation on enclosures
The heat exchanger must be correctly installed.
The roof plate of the enclosure must not be allowed to give
under the weight of the heat exchanger.
If necessary, additional stays should be used. Do not
obstruct the air inlets and outlets of the internal circuit.
Note:
For TopTherm roof-mounted units, TS 8 roof plates prepared
with mounting cut-outs and reinforcement strips for all standard enclosure sizes are available as an accessory (Cat. 31,
page 664).
When installing after the unit has been assembled, the twinthreaded bolts supplied loose should be screwed into the
core holes in the plastic base on the underside of the device,
with a maximum torque of 3 Nm.
52
Rittal System Climate Control
Air/water heat exchangers
Air routing
Free air circulation
200
It is important to ensure “even” air circulation inside the
enclosure. Air inlet and outlet openings in the internal circuit
must on no account be obstructed by electrical installations.
This would prevent air from circulating inside the enclosure.
Under such conditions, the cooling capacity of the device
would not be adequately utilised. A clearance of > 200 mm
must be guaranteed.
Note:
Wall-mounted cooling units should never be fitted directly
behind the mounting plate. Active power components are
located on the front of the mounting plates. The heat
exchanger would then operate in its own air short-circuit.
If it is impossible to install the device any other way, appropriate air baffle plates should be used, and air inlet and outlet
openings should be provided in the mounting plate.

Air-ducting system
for TopTherm roof-mounted air/water heat exchanger
With the air duct system, it is possible to route the cold air

eliminates the risk of “short circuits” in the air circulation due
to self-ventilated components.
Note:
● Never direct the cold air flow straight at active components.
● Route the air duct system directly downwards with no
bends.
● Cold air must be able to escape unobstructed at the end of
the duct.
● Additional deflections will reduce the useful cooling output.
● When using the ducting system, the performance of the
heat exchanger may be reduced, depending on the
respective application.
● The air duct system should not be extended.

connected to one of the two condensate nozzles (1 or 2). The
drain which is not required should be tightly sealed. The
condensate must be able to run off freely. If the condensate is to be drained off over a greater distance, then
care must be taken to ensure that the hose is free from
kinks and checked for correct drainage. Units with a Comfort controller are additionally equipped with a condensate

Air/water heat exchanger
Benefits
The air of the enclosure interior may also be cooled to below
the level of the external temperature, if required, by using
cooling water from a central recooling system.
The ingress of dust from outside into the cooled enclosure is
prevented. The waste heat from the enclosure does not raise
the temperature of the ambient air, provided the heat
exchanger and cold water supply system are spatially separated from one another.

Effective in extreme
conditions
in three mounting variants:

● Integrated into the TS 8 side
panel. This installation form
uses the space behind the
side panel of the TS 8.
By integrating the air/water heat
exchangers into an existing
cooling water circuit or connecting to a central recooling system, the necessary heat loss
can be dissipated with exceptionally low energy costs.
Air/water heat exchangers may
even be used in particularly
extreme ambient temperatures
from +1° to +70°C. Even
extreme levels of contamination
in the ambient air, e.g. with dust
and oil, do not affect functioning. High heat losses are dissipated in the most confined
spaces, without emitting them
directly to the ambient air. A high
operating ratio is achieved,
thanks to the large surface area
of the heat exchanger unit.
Leak monitoring of roofmounted units
Safety instructions
● When installing the device,
the condensate discharge
must be routed out of the
enclosure!
● In order to avoid frost damage, the minimum permissible water temperature of +1°C
must not be undercut at any
point in the water cycle!
● Always obtain the manufacturer's consent before adding
anti-freeze agent!
● During storage and transportation below freezing point,
the water cycle should be
drained completely using
compressed air!
● Only set the temperature as
low as is strictly necessary,
since undercutting the dew
point with a falling water inlet
temperature will result in condensation!
● It is very important that the
enclosure is sealed on all
sides (IP 54), particularly the
cable entry (condensation)!
In order to ensure that the enclosure interior is not at risk from
cooling water, the sensor reports
a leak in the event of water in the
corrosion-resistant base tray.

Outstanding performance and design
The requirement for use of air/air heat exchangers is that the
ambient temperature must be below the required enclosure
internal temperature.
Dust and aggressive ambient air are unable to enter the
enclosure interior, thanks to the two separate air circuits.
In all situations where the ambient air is sufficient for cooling,
air/air heat exchangers offer effective, energy-saving solutions. The high specific thermal output is attributable to the
special construction and functional design of the heat
exchangers:

In the paper and wood-processing industries, for example,
particular requirements are placed on climate control components. They ensure good internal ventilation and heat dissipation from the enclosure. At the same time, they also prevent the ingress of super-fine dusts.

Air/air heat exchangers are ideal for this purpose, since they
effectively dissipate the heat from the enclosure with their two
hermetically separate air circuits based on the reverse current or counter-current principle, and prevent the ingress of

Air/air heat exchangers
Selection criteria
Cool ambient air
Air/air heat exchangers utilise the ambient air to cool the air
in the enclosure interior. Based on the counterflow principle,
the completely separate airflows are routed through the heat
exchanger module by powerful fans.
● Ambient conditions: The ambient temperature Tu must be
lower than the permissible enclosure interior temperature.
A temperature difference of 10 K is ideal.
● Also ideal for use in dusty ambient conditions.

Flow and siting conditions

Internal/external mounting
Air/air heat exchangers may optionally be mounted on the
outside or inside of the enclosure. The slimline design facilitates external mounting on the door, rear panel and side panels. The range also includes a special heat exchanger for
roof-mounting.
By diverting the waste air upwards, this prevents the creation of disruptive air flows in front of the enclosures.
The fans in the internal and external circuit may be activated
separately and thus adapted ideally to the ambient conditions.

Air/air heat exchangers
Assembly
Sealing of the enclosure
The enclosure must be sealed on all sides (IP 54). Particular
attention should be paid to the sealing of the area around the
cable entry openings and above all, the floor section of the
enclosure.
Additionally, the door seal must be in perfect condition.
The sealing material included with the heat exchangers must
be applied in accordance with the installation instructions.
Take care not to bend the side panel or enclosure door.
7.3
External circuit
Flow and siting conditions
In the outer circuit, air/air heat exchangers should be spaced
200 – 400 mm from the wall and/or from each other (air inlet
and outlet openings).
If this clearance cannot be maintained, air baffle plates will
need to be used.
Siting options
Wall-mounted heat exchangers may be mounted on the rear
panel, side panels or door of the enclosure.
Distance from the wall
at least 200 – 400 mm
62
Rittal System Climate Control
Air/air heat exchangers
Air routing
Free air circulation
200
It is important to ensure “even” air circulation inside the
enclosure. Air inlet and outlet openings in the internal circuit
must on no account be obstructed by electrical installations.
This would prevent air from circulating inside the enclosure.
Under such conditions, the capacity of the device would not
be adequately utilised. A clearance of > 200 mm must be
guaranteed.
Note:
Wall-mounted cooling units should never be fitted directly
behind the mounting plate. Active power components are
located on the front of the mounting plates. The heat
exchanger would then operate in its own air short-circuit.
If it is impossible to install the device any other way, appropriate air baffle plates should be used, and air inlet and outlet
openings should be provided in the mounting plate.
7.4
Internal circuit – Wall-mounted units
Attention should be paid to components/electronic components equipped with their own ventilation systems, such as
blowers and axial fans. If their air flow is directed against the
chilled air flow of the heat exchanger, this could cause an air
short-circuit and prevent adequate climate control. In a worst
case scenario, the heat exchanger will suffer an air short-circuit.
Note:
Never direct the chilled air flow at active components.

Fan-and-filter units
Potential applications/selection critiera
Ambient conditions
Fan-and-filter units utilise the ambient air for direct
cooling of the enclosure interior.
This requires cool, reasonably clean ambient air.
Cool
Application diversity and design
In most cases, it makes sense to install
the axial fan with the air directed from
outside into the enclosure so that overpressure is created inside the enclosure, as per the delivered state. This
helps to avoid the ingress of unfiltered
ambient air.
Advantage: Aesthetics and function
Typical of the Rittal fan-and-filter unit
design is the extremely low build height.
The super-slimline vent grille guarantees
optimum air throughput with low noise
generation. Combined with the technical features, Rittal fanand-filter units meet all application requirements.
8.1
Fan-and-filter units are ideal for dissipating heat loads costeffectively. The pre-requisite is that the ambient air must be
relatively clean and with a temperature below the desired

Potential applications/selection critiera
Practical example of a fan-and-filter unit
Fan-and-filter units are used in virtually all segments of industry: from the smallest enclosures, to command panels and
consoles, through to large and bayed enclosure systems.
They are the easiest method of protecting against overheating and hotspots.

The basic pre-requisite for their use is that the ambient temperature must be significantly below the enclosure internal
temperature.
A wide range of control units such as thermostat, hygrostat
and speed control for noise minimisation extend the applications e.g. to include the office sector and laboratories.
EMC fans meet the requirements for increased RF shielding.
Particularly when using fan-and-filter units in conjunction with
PC enclosures or monitor panels, DC variants are used which
provide effective protection from interference.

Enclosure heaters
Applications
Ambient conditions
Heaters evectively prevent the formation of hazardous
leakage current caused by condensation.
Cool
Damp
Enclosure heaters are used to prevent the formation of condensation inside the enclosure and maintain a constant
minimum operating temperature (e.g. when the system is
switched off overnight). They achieve thermal outputs of 10
to 1000 watts.
Modern enclosure heaters are equipped with PTC elements.
By virtue of their characteristic curve, these are self-regulating.
From an energy and environmental viewpoint, it is nevertheless advisable to use either a thermostat or hygrostat, or possibly both together, depending on the application, for control
purposes. If both are used, both control devices activate the
heater via a contactor.
Installation position
Heaters should always be installed in an upright position.

Assembly / electrical connection
Installation option for the enclosure heaters
The device is attached vertically, i.e. with the connection
cable pointing downwards. The connection cable should be
tightly secured. In order to create the required convection, a
distance of at least 50 mm from components must be maintained above and below the device. The thermal safety clearance from neighbouring components is at least 35 mm. Provided these clearances are adhered to, an ambient
temperature of 65 °C will not be exceeded.
Installation versions:
1 Direct screw-fastening to the mounting plate

Electrical connection
Due to the particular characteristics of the PTC thermal element, the startup current is approx. 1.8 A for around 0.5 sec.
A slow pre-fuse (gL) is therefore essential.
Rittal System Climate Control
According to IEC 6100-4-5, a fuse is to be provided by the
customer for pulse loads in excess of 1000 V. The surface temperature of the aluminium section is regulated
automatically. A separate thermostat (SK 3110.000)
should be connected to control the room temperature. To
control the air humidity inside the enclosure, a hygrostat
(SK 3118.000) may be connected upstream.
71
Enclosure heaters
Benefits
The prerequisite for optimum conversion of electrical energy
into thermal energy is perfect interaction between the thermal output, surface temperature and ambient temperature.
Conventional resistor
heaters
The surface temperature is limited via an additional safety thermostat. As a result, the heater is
forever cutting in and out, which
means that the continuous thermal output actually produced is
low.
Rittal heaters with PTC technology
Unlike conventional resistance
heaters, in thermistors (PTCs),
power consumption automatically decreases as the intrinsic
temperature rises. The advantages of this dynamic output
behaviour are as follows:
● Limitation of surface
temperature
without additional temperature protection devices
● Self-regulation
allows direct adaptation to the
ambient temperature. In other
words, as the enclosure internal temperature falls, the thermal output rises (refer to performance diagrams on the
Internet)
● Consistent thermal
output
across a broad voltage range
(e.g. 110 to 240 V AC/DC).
● Special voltages
possible in the low voltage
range (e.g. 12 V, 24 V)
● Long service life
● Compact, vibration-free

Installation:
Function principle:
The fan unit with six individual fans ensures optimum air circulation at the cooler for efficient dissipation of the heat losses arising in the housing.
The unit can be connected either to an existing
coolant circuit or else to an external recooling
system.
Benefits:
● Maximum performance despite minimal space
requirements
● No reduction of the original protection category
● No external add-ons necessary
Operating housing cooling for Comfort Panels and
the like, also suitable for use in special enclosures such as stainless steel enclosures for the
food industry.
Cooling units may be ordered for heat losses of
up to 300 W on a project-specific basis.

In open bayed enclosure systems which are not separate
from one another, cooling units and air/water heat exchangers with Comfort control should always be used. These may
be placed in master/slave mode via bus cable SK 3124.100:

Interface board
The new interface board (SK 3124.200) is an extension for
TopTherm cooling units and air/water heat exchangers with
Comfort controller; see page 41. In this way it is possible,
e.g. to monitor a master/slave combination of up to 10 cooling units. Control is achieved via standardised interfaces
RS 232 (DB9) or RS 485, a PLC interface. RS 422 (RJ 45
jack) is the connection to the Rittal CMC-TC. Remote monitoring via TCP-IP, graphical interfaces for operation, evaluation
and control, documentation, and connection to additional
sensors for access control facilitates monitoring.
The extension card is built into a 1 U plastic housing. A voltage supply of 24 V (DC) is required. This can be supplied
from the CMC-TC via long-range power pack or externally via
a Kycon connector.

Master/slave operation
Description:
The address of the master depends on the number of
attached slave units (09 = master with 9 slave units). The
address of a slave device always begins with a 1. The second number represents the actual address. Up to a maximum of 9 slave units may be operated with one master unit,
whereby any unit may be a master. The maximum overall
length of all connected units is 50 m. single-phase and
3-phase units may be connected.

Notes on connecting cooling units and air/water heat exchangers
in the master/slave combination
Only one unit may be configured as master, and the address
ID must match the number of slave units. All slave units must
have different addresses, and the addresses must be in
ascending order without any gaps in between.
If changes are made to the configuration of the master,
please proceed as follows:
1. Disconnect any existing connections
between the RTT I/O unit and the PU
– Timeout on the PU
2. Confirmation on the PU
– Unit has been removed
4. Make the connection between the RTT I/O unit
and the PU
– Message on the PU "Unit found"
5. Wait 60 s then confirm
– RTT I/O unit is correctly displayed with all its slaves
in the Web.
Configuration settings on the cooling unit master regarding the number of slaves must only be made if there is no
supply voltage at the RTT I/O unit, neither from the PU
nor externally.
3. Make the required changes to the master

Accessories
Regulation/control
Digital temperature
display/thermostat:
SK 3114.100/.115/.024
For installing on the enclosure door or wall and in a
cooling unit or heat
exchanger.
Speed control
Temperature-dependent
speed control to minimise
noise and save energy in
part-load operation.
Thermostat: SK 3110.000
Especially suitable for controlling fan-and-filter units,
heaters and heat exchangers, this thermostat can also
be used as a signal generator for monitoring the enclosure internal temperature.
Hygrostat: SK 3118.000
The hygrostat switches on
the heater and/or fan when a
preset relative humidity in
the enclosure is exceeded.
In this way, the relative
humidity is raised above the
dew point, and condensation on assemblies or on
electronic components is
avoided.
For more accessories, see Catalogue 31, from page 658.

Service packages for every aspect
of enclosure climate control
Load test
482.6 mm (19˝) slide-in equipment which simulates the thermodynamic response of servers
allows you to determine in advance whether your
cooling system is adequate for any planned
extensions. Furthermore, after installing the LCP
family, the cooling response can be tested
directly, without the presence of a server.
Load tests as the optimum basis for
planning.
Intelligent wireless sensor
technology
Sensors the size of a button record the temperature and humidity at specified locations in the
rack. The location and time-dependent readings
are extracted and displayed. The result is a 3D
analysis of the data centre's cooling response.
With sensor technology for 3D analyses.
Piping network calculation
The Rittal specialists use a software package to
design and dimension the pipe networks of liquid
cooling systems, with due regard for the architectural conditions. The specifications thereby
obtained allow the local installation engineer to
start work immediately.
Perfect dimensioning of pipe networks
CFD (Computational Fluid
Dynamics)
A 3D computer simulation is used to visualise the
thermodynamic response of the planned data
centre with server racks and climate control system. Predicting the temperature, speed, pressure
and hence flow conditions in the data centre facilitates fast reaction times.
Forward planning with CFD.
Thermography
Using a thermal imaging camera which illustrates
the temperature conditions (surface) inside the
data centre with colour coding, hotspots can be
located and eliminated via suitable means.
