KWL® from Helios.
Energy saving for a healthy climate.
Today more important than ever.
The political measures set for the
global climate will affect the construction industry over the next few
years. The main aim is to reduce the
amount of greenhouse gases by
40 % before the year 2020. In these
circumstances the demand for energy efficiency standards, for the
establishment and renewal of buildings, increases further.
Improved energy efficiency leads to
an airtight building shell.
The higher efficiency requirements become apparent in the European and
national legislation. Already the introduction of the Energy Saving Regulation (EnEV) 2009 as well as the renewable Energy HeatAct (EEWärmeG)
brought a clear aggravation of the
structural standard. Currently an
amendment is planned with the EnEV
in 2012/2013, which represents a further step towards the attainment of the
legally required “Zero-Energy-House”
in new and old buildings. Usually the
increasing energetic requirements are
realised by optimal insulating measures
at the building shell – with the consequence that this becomes increasingly
airtight.
2
DIN 1946-6 requires the proof of a
ventilation concept.
Due to the tight building shell the EnEV
requires the guarantee of “the minimum air renewal necessary for the
purpose of health”. Hence, for each
new building or renovation project a
ventilation concept is to be provided in
accordance with DIN 1946-6. This is
not least in reaction to the frequently
insufficient ventilation of flats, the expensive structural damages accompanying this and the health-related burdens. If the proof of a ventilation concept has failed, high costs and lawsuits are unavoidable in the event of
damage.
Controlled, mechanical ventilation is
essential.
Ventilation concepts for moisture protection and minimum air exchanges in
thermal insulated buildings can be fulfilled only by controlled, mechanical
ventilation. Opened windows would
negate the desired heating cost saving
from the energetic point of view. The
proportion of ventilation heating losses
through opened windows increases to
over 50 % of the total heating loss of a
energy efficient building.
KWL® from Helios.
Healthy, comfortable climate ... and you feel good.
The ventilation concept with added value.
A KWL®-unit from Helios for controlled ventilation with heat recovery
guarantees the moisture protection
according to DIN 1946-6, completely, permanently and independently
of user behaviour. Beyond that the
necessary minimum air exchange is
automatically ensured round the
clock.
Research proves that people living or
working in inadequately ventilated buildings suffer from many ailments such
as headache and allergies. On average, humans spend 90 % of their lifes in
closed buildings. Therefore, it is of prime importance to provide healthier indoor air – free from odours and high
humidity.
Fresh air for humans and buildings.
KWL® guarantees the maintenance of
the building fabric and creates a healthy and comfortable climate in otherwise airtight and well insulated buildings
around the clock.
Energy savings are achieved by improved insulating measures and through
using heat recovery with KWL®. This
leads to a further improvement of the
energy efficiency. The heating costs
are reduced by up to a third through
heat recovery and the energy saving
EC-fan technology.
avoids mildew, protects the building
fabric and ensures, in the long term,
the real estate value of the property.
KWL® from Helios provides pleasantly
tempered, draught-free and clean air
round-the-clock. It ensures a balanced, healthy comfort climate throughout the year.
Toxins stay outside, the used air is
controlled and efficiently renewed.

KWL® from Helios.
Perfectly tuned to each other.
Apart from the main components
what matters most is an integrated
concept with a KWL®-unit. Perfectly
harmonising all the elements leads
to the best results.
Helios offers an integrated and
coordinated KWL®-system solution
which thereby guarantees simple
planning, safe assembly and the
highest efficiency. The program covers KWL®-units with an air flow volume up to 2600 m³/h which are
suitable for single-and multi-family
houses as well for commercial and
industrial applications.
Various services like special KWL®professional seminars and practice
workshops as well as the almost
self-explanatory software tool
KWLeasyPlan make the layout,
planning and installation even
easier.
That’s the way it works.
Stale air with humidity, toxins and
smells are extracted from the kitchen,
bathroom and toilets via design valves
to the heat exchanger in the ventilation
unit. The outside air, which takes up
the heat energy of the extract air with
a tested efficiency of up to 90 %, flows
through this and is hermetically separated at the same time. This process
can be optimised by connecting an
earth heat exchanger.
The air then flows through supply air
valves or air inlets into the living rooms
and bedrooms and creates a healthy
and comfortable climate around the
clock. Transfer elements ensure air circulation within the property. The exhaust air is released outside by passing
through a roof or wall outlet.

Wall installed unit with heat recovery and EC-technology
For single rooms, with air flows up to approx. 60 m³/h
KWL EC 60
Compact wall unit with heat
recovery for ventilation of single
rooms.
KWL EC 60 is the proven solution for comfortable indoor climate and energy saving in single rooms. Ideal to bring existing buildings up to modern
standards in the course of a renovation and to EnEV standard.
KWL EC 60 supplies small and
larger single rooms. For a medium-sized flat the installation of
several units is recommended.
Installed in no time – ideal for
renovation
KWL EC 60 is the optimal renovation solution, also for additional installation. The access to the outside air is simply made by a core
drilling in the outer wall in which
the wall sleeve is inserted.
This can be done simply during the
facade renovation. Two protection
cover plates close the openings.
The installation of the elegantly
designed external facia which is
made from high grade-steel takes
place with the final plastering
works. During the interior work the
unit is inserted into the wall sleeve
and connected electrically.
Only the elegant facia is seen inside the room. Therefore the KWL
EC 60 blends in everywhere beautifully and the facia shields the view
of the fan interior completely.
Aluminium plate heat exchanger
with efficiency of more than
70 %
Expensive heating energy is saved
with KWL EC 60 and its efficient
large heat transfer area aluminium
plate heat exchanger with efficiency
of more than 70 %.
ECgreenVent® by Helios
Efficient energy-saving ventilation
units with EC-technology including
the Helios KWL EC 60 are given
the GreenTec label. KWL EC 60 allows the demand ventilation with
heat recovery of individual rooms;
several units can be controlled independently. Regulating is not necessary.
Operating mode of the
KWL EC 60 ventilation with heat
recovery
Two highly efficient fans with energy-saving EC-motors move the
supply and extract air. Smells and
stale room air are extracted outside, fresh and preheated air is supplied into the room.
The heat of the extracted air is recovered by the large heat transfer
area aluminium plate heat exchanger and transferred through
the plates to the incoming fresh
external air, so both air flows remain separated.

Enthalpy heat exchanger for additional humidity recovery.
Ideal atmospheric humidity. Highest efficiency. Comfortable ventilation.
Heat and humidity recovery
for a comfortable climate.
KWL®-units with combined
heat and humidity recovery
by enthalpy exchanger provide for a comfortable, healthy
room climate, without additional energy consumption
and without use of an
atmospheric humidifier.
12
Ideal room climate provides
a healthy environment
In living quarters the relative
room humidity should lie between 30 – 60 %. With too low
humidity mucous membranes,
dry dust and electrostatic charges increase.
These effects become apparent, in the cold season, if the
outside air has a high saturation level so that when warming,
the relative air humidity decreases inside the room. For example: With -5° outside temperature and 21° inside the room
the humidity of originally 100 %
drops to less than 17 %.
In this range it becomes uncomfortable.
Ventilation units with enthalpy
heat exchanger recover, in addition to the heat, up to 65 %
of humidity from the extract air.
This is used to warm the outside air, which flows into the
living and reception rooms with
a comfortable, healthy moisture content.
Ventilation units with enthalpy
heat exchanger from Helios
achieve TÜV-approved efficiencies to DIBt of up to 116 % in
the design sizes KWL EC 200
W to 500 W.
Operating mode of enthalpy
heat exchanger
The water molecules of the extracted room air condense on contact with surfaces of the enthalpy
heat exchanger. They move the
water in a similar way to plants,
through the membrane.
At the membrane surface of the
supply airside the water molecules
are absorbed by dry outside air. A
salt-crystalline layer on the membrane of the enthalpy heat ex-
changer guarantees hygiene and
efficiency with the humidity transmission process. It ensures the
water retains its molecular configuration to enter the supply air flow.
Extract and supply air flows are
hermetically separated from each
other, so that an overall transfer of
organic particles or odours is excluded.
Ventilation units with enthalpy
heat exchanger offer convincing
advantages:
– Energy saving heat recovery
and humidity recovery in the
cold season.
– Humidity recovery from the extract air up to 65 %, depending
on the interior air humidity.
– Additional humidifiers are unnecessary.
Helios KWL®-systems with enthalpy combine the advantages of
heat recovery with those of a healthy interior air humidity in an optimal way. The energy stored in the
molecules help retain an improved
energetic total balance of the heat
recovery in comparison to heat exchangers without enthalpy. Enthalpy heat exchangers from Helios
thereby achieve heat recovery efficiencies of more than 100 %.

Maße in mmin mm
Dimensions
Extremely flat ventilation unit with heat
recovery for compact and space
saving ceiling installation. With wide range of application in apartments, commercial and industrial applications.
Certified according to passivehouse standards. With highly efficient aluminium heat exchanger and energy-saving ECmotors. In different comfort- and
equipment versions.
■ Casing
Made from galvanised sheet
steel. Heat and noise insulated
with 30 mm thick mineral wool.
Inspection openings for filter
change at the underside of the
unit which can be opened without tools. Ceiling installation is
carried out with vibration absorbing mounting elements (included in delivery).
■ Heat exchanger
Large surface cross counterflow
heat exchanger from aluminium
with an efficiency up to 90 %.
Easy to remove.
■ Fans
Two silent highly efficient ECfans with backward curved impellers ensure highest efficiency.
The special control system
make a constant air flow volume
or constant pressure regulation
possible.
28
■ Ducting
Installation-friendly connection of
the ducting for intake, exhaust,
extract and supply air using
ducts with nominal diameter of
250 mm.
■ Condensation outlet
A separate condensation collector below the heat exchanger
makes maintenance work easier.
Condensation outlet is located
next to terminal box. Ball siphon
included in delivery. To be connected to drain pipe by installer.
■ Air filter
Standard equipment:
Supply of cleaned outside air
using a F7 filter. Extract air passes through a F5 filter before entering the heat exchanger. All filters are pressure monitored and
are easy to remove.
■ Summer operation
Comes with automatic bypass
function for maximum comfort
as standard.
■ Frost protection of
heat exchanger
A electric pre-heater battery
heats the intake air when the
temperature is too low. This prevents ice from building up in the
heat exchanger and ensures optimal heat recovery during the
complete heating period.
■ Speed control
The comfort controller for surface mounting with touchscreen
(included in delivery) and userfriendly menu navigation makes
the following functions possible:
– Operation directly via touchscreen.
– Freely definable operating levels
within the performance curve
values.
– Choice between constant air
flow volume or constant pressure regulation.
– Demand-driven ventilation using
CO2-, VOC (mixed gas) or humidity sensor.
– Initial start-up (automatic determination of the system performance curve).
– Control of external shutters.
– Connection of a fire alarm contact.
– Weekly or daily program.
– Pressure monitoring of filter pollution.
– Display of required filter change,
operating state, error messages.
– Different access levels.
Alternatively the ventilation unit
can be controlled via ModBus
(RS 485).
■ Electrical connection
Easily accessible terminal box
located on the side of the casing. Isolator switch, lockable via
padlock, for maintenance work
can be operated from the underside of the unit.
■ Heater battery
(KWL EC.. Pro WW)
The integrated water heater battery provides a comfortable and
energy-efficient heating of the
supply air. The target temperature simply is set at the controller.
For the control of the water heater battery the use of the hydraulic unit (WHSH 1100 24V
(0-10V), accessories) is recommended.

Dimensions in mm
Central ventilation
units with heat recovery for compact
and space-saving
floor installation
(vertical). With wide range of application in apartments, commercial and industrial applications. Certified according to passive-house standards. With
highly efficient aluminium heat
exchanger and energy-saving
EC-motors. Optional with built-in
water heater battery.
■ Casing
Made from galvanised sheet
steel. Heat and noise insulated
with 50 mm thick mineral wool.
Inspection openings for filter
change at the two side doors
which can be opened optionally
without tool or using a socket
wrench. Both sides panels are
completely removable for free
access of all elements. The unit
is suitable for the vertical floor installation in the interior. Anti vibration mounts can be placed
below (on site) to prevent the direct transmission of vibration and
structure-borne noise on parts of
the building.
■ Heat exchanger
Large surface cross counterflow
heat exchanger from aluminium
with an efficiency up to 90 %.
Easy to remove.
■ Fans
Two silent highly efficient ECfans with backward curved impellers ensure highest efficiency.
The special control system
make a constant air flow volume
or constant pressure regulation
possible.
34
■ Ducting
Installation-friendly connection of
the ducting for intake, exhaust,
extract and supply air using
ducts with nominal diameter of
250 mm. The unit can be installed either way round, so that intake- and exhaust air as well as
extract- and supply air connections can be left or right.
■ Condensation outlet
The unit is equipped with a condensate tray made from high
quailty steel. The condensation
outlet is located at the bottom.
Ball siphon included in delivery.
To be connected to drain pipe
by installer.
■ Air filter
Standard equipment:
Supply of cleaned outside air
using a F7 filter. Extract air passes through a F5 filter before entering the heat exchanger. All filters are pressure monitored and
are easy to remove.
■ Summer operation
Comes with automatic bypass
function for maximum comfort
as standard.
■ Frost protection of
heat exchanger
A electric pre-heater battery
heats the intake air when the
temperature is too low. This prevents ice from building up in the
heat exchanger and ensures optimal heat recovery during the
complete heating period.
■ Speed control
The comfort controller for surface mounting with touchscreen
(included in delivery) and userfriendly menu navigation makes
the following functions possible:
– Operation directly via touchscreen.
– Freely definable operating levels
within the performance curve
values.
– Choice between constant air
flow volume or constant pressure regulation.
– Demand-driven ventilation using
CO2-, VOC (mixed gas) or humidity sensor.
– Central building control system
via ModBus (RS 485).
– Initial start-up (automatic determination of the system performance curve).
– Control of external shutters.
– Connection of a fire alarm contact.
– Weekly or daily program.
– Pressure monitoring of filter pollution.
– Display of required filter change,
operating state, error messages.
– Different access levels.
■ Electrical connection
Easily accessible terminal box
located on top of the casing.
Isolator switch, lockable via padlock, for maintenance work can
be operated from the top of the
unit.
■ Heater battery
(KWL EC.. Pro WW)
The integrated water heater battery provides a comfortable and
energy-efficient heating of the
supply air. The target temperature simply is set at the controller.
For the control of the water heater battery the use of the hydraulic unit (WHSH 1100 24V
(0-10V), accessories) is recommended.

■ Advantages
– Constant room climate with ideal
humidity level.
– Avoidance of expensive damage
to furniture, wooden floor surfaces and antiques.
– Relief of allergy complaints and
physical loads. Strengthening of
the body's defences by a shortening of the life span of bacteria
and viruses.
– Reduction of fine dust and electrostatic loadings.
■ Special HygroBox
characteristics
– Constant supply air humidity
and temperature in all rooms.
– Principle of the natural evaporation prevents excessive humidity.
– Hygienic harmless by UVC disinfection.
– Fully automatic mode with automatic summer switch-off.
– Low-maintenance and easy installable.
– Low operating cost by use of
the evaporation energy from the
existing heating system.
■ Functional principle
The HygroBox is an active humidification unit for the integration
into new or existing KWL®-ventilation systems with heat recovery. The fresh outside air is fed
through the heat exchanger of
the KWL®-unit and takes up the
heat energy from the extracted
air. The preheated air is supplied
afterwards to the HygroBox, in
which an active and automatic
humidification takes place ac-
42
cording to the natural evaporation principle. A rotor fitted with
lamellas turns inside the unit
continuously in a water bath and
passes water molecules over
the moistened lamella surface
on to the warmed supply air.
Regardless of the operating level
of the KWL®-system as well as
of outside influences of the weather the HygroBox keeps the
preselected relative air humidity
consistently and provides in
such a way for a healthy climate
with ideal humidity level.
■ Delivery
Compact unit, ready to plug in,
including water hose and water
filter.
■ Heater battery
■ The HygroBox is equipped with
a water (type WW) or electric
heater battery (type EH). The
supply air is warmed up before
humidification and provides in
such a way for the required evaporation energy and pleasant
temperature of the supply air.
■ With heating systems with low
flow water temperature (e.g.,
warm pumps) a low temperature
heater battery (KWL-NHR.. ,accessories, see on the right) is to
be connected at the outlet side
of the HygroBox.
■ Summer operation
■ With sufficiently high humidity level of the outside air (e.g. in the
summer) the HygroBox switches
automatically into the standby
mode. In this condition no water
is in the unit and the rotor
stands still.
Pressure loss [Pa]
Especially developed for ventilation systems in residential buildings and offices. The Helios

Ground-to-brine heat exchanger SEWT
SEWT-kit
The ground-to brine heat exchanger substantially increases
the efficiency of the ventilation
units.
SEWT saves even more energy
and reduces costs of heating to
a minimum. The optimal add-on
for ventilation systems with heat
recovery.
■ Operation
SEWT uses the fact that the
temperature below the ground is
relatively constant over the year.
The undersoil collector hose is
laid 1.2 m deep.
The hydraulic unit circulates
the brine-liquid according to the
temperature outside. The brineliquid serves as heat transfer
medium and delivers the heat to
the the supply air via the heat
exchanger unit.
■ Effects:
■ During winter SEWT achieves a
pre-heating of the cool outside
air up to 14 K. This results in the
intake air flowing into the ventilation unit with usually more than
0 °C and therefore prevents the
heat exchanger from icing up.
The benefits are a higher heat
recovery factor and a higher
supply air temperature. An additional heater battery is only needed on extremly cold days.
■ On hot summer days the SEWT
causes a reduction in temperature.
■ During transition periods
the circulation of the brine-liquid
is provided by the hydraulic unit
as a function of the outside temperature. Therefore the outside
air always arrives at the ventilation unit energetically optimised.
Saving energy and always provides comfortable room climate.
■ Information on planning
■ To ensure the highest possible
heat transfer, the undersoil collector hose should be laid in at
least 1.2 m depth as there is a
constant temperature of about
8-12 °C throughout the year.
The soil temperature increases
the deeper the ducts are laid
and becomes constant.
■ To increase the heat exchange
the hose should be laid directly
under the soil in a sandbed. Furthermore, a minimum space of
0.5 m from one hose to the
other should be observed for
two parallel tubes.
■ Alternatively to laying the hose
horizontally in a zigzag arrangement under the soil a vertical
bore hole can be used.
■ Delivery
■ According to the installation order on the building site and to
ensure an optimised transport
the SEWT is delivered as kit.
The SEWT-kit ensures full
functionality and perfect fitting
accuracy. It consists of three delivery-sets as described on the
right page.

Ground-to-air heat exchanger LEWT
LEWT-kit
The undersoil air heat exchanger
LEWT substantially increases
the efficiency of the ventilation
units with heat recovery.
■ Advantages
– Provides additional pre-heating
during winter without any further
energy requirements.
– Prevents the heat exchanger
from icing up.
– Pleasant cooling on hot days.
– Additional heating of the supply
air is only necessary when outside
temperature is very low.
– Comes as a complete kit with
perfectly fitting components.
■ Functional principle
LEWT uses the fact that the
temperature below the ground is
relatively constant all year. The
outside air is not taken in directly but passes through the undersoil collector duct installed in
approx. 1.2 to 1.5 m deep; the
total length should be at least
40 m.
■ Effects:
■ During winter LEWT achieves a
pre-heating of the cool outside
air up to 14 K.
This results in the intake air
flowing into the ventilation unit
at more than 0 °C usually and
therefore prevents the heat exchanger from icing up. The benefits are a higher heat recovery
factor and a higher supply air
temperature. The heater battery
is only needed on very cold days.
■ On hot summer days the SEWT
causes a reduction in temperature.
■ During transition periods the
intake is by either the air passing
through the undersoil collector
or the direct intake opening depending on the outside temperature detected by the sensor.
The electric bypass shutter controls the air intake automatically.
The outside air reaches the ventilation unit energetically
optimised which additionally

saves energy and provides a
comfortable climate within the
rooms.
■ Delivery
■ According to the installation
order on the building site and
to ensure an optimised transport
the LEWT is delivered as a kit. It
consists of three delivery sets as
described on the right hand
page.
■ The single components perfectly
fit together as a sophisticated
system. This ensures easy,
quick and precise mounting with
a high installation reliability.
LEWT-kit
Ref.-No. 2977
■ Information on planning
■ To ensure the highest possible
heat transfer, the undersoil air
collector duct should be laid in
at least 1.2 m depth as there is
a constant temperature of
about 8 °C throughout the year.
The soil temperature increases
the deeper the ducts are laid
and becomes constant.
■ When installing it is important to
consider that the condensation
drain requires an incline of at
least 2 %.
■ To increase the heat exchange
the duct should be laid directly
under the soil in a sandbed. Furthermore, a space of 1 m from
one duct to the other should be
maintained when laying two
ducts parallel.
■ To keep the downstream
pressure loss minimised a
bending radius of at least 1 m
is recommended.
■ Basic scheme for the laying: Buildings without basements
The undersoil collector reaches the building subsurface through the base
plate. For revision purposes a drain is required by customer.

Flexible ducting system FlexPipe® plus
Round 75 mm Ø in combination with Oval 51x114 mm
FlexPipe plus round- and oval ducting system. Arbitrarily combinable.
FlexPipe® plus is the further development of the successful air
distribution system FlexPipe®
and unites round and oval pipe
as of now in a clever system package with all conceivable roundoval-combinations.
The new oval pipe has the identical
hydraulic cross-section and pressure loss like the round pipe as well
as a point-symmetric design. This
leads to unique advantages:
– No matter if it’s planning and layout or installation and adjustment
or maintenance, round and oval
pipe behave completely identical.
– Depending on the structural
condition, therefore any changes
between round and oval pipe by
means of adapters are possible.
This along the line as well as
from the distibution box away.
This offers greatest possible
■ FlexPipe® plus contains two design types which are arbitrarily combinable:
■ FRS.. 75, round:
Outer-ø: 75 mm, inner: 63 mm
for air flow vol. up to 30 m³/h.
For laying into concrete.
High resilience (SR24 > 8 kN/m²).
Bending radius horizontal and
vertical 150 mm.
■ FRS.. 51, oval:
51 x 114 mm, for air flow volume up to 30 m³/h, ideal for space-saving laying e.g. on the unfinished floor or in the wall. Bending radius horizontal 300 mm,
vertical 200 mm.
■ Laying, handling, initiation
■ Easiest planning thanks to identical pipe cross-sections and
pressure losses.
■ Fast to install through star shaped laying.
■ Convenient handling due to the
light weight.
■ Fast initiation as the adjustments
are reduced to a minimum.
■ Constant air distribution.
■ Easy to clean, hygienically
perfect.
■ Duct characteristics and advantages
■ The round and oval pipe consists
of quality-assured PE-HD made
of new raw material.
■ The outside is ribbed where as
the inner surface is absolutely
smooth and antistaticly coated.
This minimizes the pressure losses and prevents flow-generated noise and dirt disposits.
52
■ The extreme horizontal and vertical bending elasticity of both pipe geometries reduces the number of required fittings to a minimum.
■ Due to the point-symmetric design the laying of the oval pipe is
vertically up- or downwards
from the horizontal line possiblewithout adapter pieces.
■ Laying-conception/installation
■ Fixing brackets on all parts for
secure fixing to floor, wall, or
ceiling.
■ Unlockable fixing clips guarantee
the fast and no-pull-out pipe
mounting on all joints.
■ By sound absorbing distribution
boxes additional cross-talk
sound attenuators are omitted.
■ Precise sealing system on all fittings for leakage-free air transportation.
■ Many different components
ensure the perfect solution for
nearly every request. There are
ceiling outlets available for all
kind of valves with ND 125 as
well as wall and floor outlets,
delivered with grilles as standard.
They each have two parallel
pipe connections for the low
pressure loss airflow of the required air flow volumes to DIN
1946-6.
freedom during planning and installation.
– The ideal, cost-effective option
can be selected at any time. The
space-saving oval pipe is mainly
used when low structure heights
are required.
– The round-oval-compatibility
leads to a low parts variety.
Stockpiling and consultation are
strongly simplified. The installation is almost intuitively carried
out.
– The point-symmetric oval design
allows the laying from the horizontal line into vertical without
the use of adapter pieces to the
position correction.

■ With FlexPipe® plus from Helios you decide for one system and have –
depending on the object requirement – the perfect solution in the access.
■ The only 51 mm super flat oval pipe is then used, when low construction height is required. The approved round pipe is offered for the
direct laying into the concrete ceiling.
■ Thanks to identical hydraulic cross-sections and pressure losses of
the two pipes and due to well-conceived system components you can
combine round and oval as required.This along the line as well as

1. Helios offers the right solution for every installation situation:
■ The distribution boxes are variably applicable: Optional as straight
through or 90° distributor, for wall or ceiling installation.
■ The multi-distribution boxes optimally are suitable as storey distributors. They can be installed in or on the raw concrete ceiling with an inspection opening from above or below.
■ With a height of only 160 mm the flat distribution box fits even in the
smallest spaces, e.g. in suspended ceilings.
■ The compact distribution box is an extract air collector and supply air
distributor at the same time and is used when kitchens and bathrooms border directly on each other.
2. Flexible to the last detail
■ All distribution boxes are supplied with tight clasping bayonet catch
caps, which are applicable (leakage-free) with one move of the hand.
■ Depending on architectural situation a combined installation of the distribution boxes with round and oval single spigots is possible. Moreover the spigots can be ordered individually (see below). The maximum
possible number of oval single spigots (FRS-ES 51, Ref.-No. 3851) is
to be requested if necessary.
■ Included in delivery: Fixing clips for the no pull out pipe mounting at
the spigots as well as bayonet catch caps with integrated seal rings
for non occupied distribution box openings.

■ Ducts conception and
mounting
■ Flat design and rigid construction
allow a trouble-free laying below
the floor screed. The substantial
range of fittings allows nearly
every course of the ducting.
■ Connection via external connectors. Fittings with sockets (35
mm insertion). Therefore, the
absolutely smooth inner surface
ensures low air flow resistance
and no barriers for dirt. However,
disinfection is possible, if desired.
■ The junction box for the supply
air and extract air routing is
installed on each floor which
simplifies the duct routing.
■ Special flat sound absorbers can
be installed within the duct route
to protect (e. g. bedrooms) from
noise (FK-SD).

Cleaning kit for distribution system FlexPipe® and RenoPipe
The universal cleaning kit is perfect
for cleaning of the flexible ducting
system FlexPipe® (DN 75, DN 63)
as well as the RenoPipe air distribution system (DN 100).
Application is optionally under
pressure (with short ways) or tension possible. With longer ducting
distances or narrow elbows the
nylon wheel brush is pulled simply
toward the distribution box, at
which the 90° elbow is used for
the vacuum connection. Via this,
the dust particles dislodged by the
nylon wheel brush are vacuumed
without problems with a commercial vacuum cleaner.
