Starting in 2012, TECNAIR LV was the first company in the market to
choose to standardise fans with EC technology on the full range of
close control air conditioners. This has resulted in energy savings of
over 40% compared to the previous generation of fans.
Today TECNAIR LV wants to maintain this leadership by choosing to be the first to:
• Provide the full range of close control air conditioners with an advanced microprocessor control system,
characterised by features that optimise unit control and system energy saving.
• Install the latest generation of EC fans, entirely controlled via Modbus® protocol, on the full range of close
control air conditioners.
• Install electronic expansion valves on the entire range of direct expansion close control air conditioners.
• Make available for brushless DC compressors with inverter control over the entire range of direct expansion
close control air conditioners.
OPTIMISING INFRASTRUCTURE
The wide range of models and accessories enables optimal configuration of
the air conditioning system. The minimum plan dimensions and the possibility
of modulating operation for all components allow development of solutions
tailored to the actual needs of the infrastructure, as well as ensuring future
expansion without high additional costs.
With the introduction of the POWER VALVE system, available as an accessory
on chilled water units, implementing the water system has been simplified,
resulting in construction cost reductions.
The SMART COOL system, instead, helps to simplify checks and maintenance operations on direct expansion
circuits, by keeping the pressure, temperature and working conditions of the whole cooling cycle under
control.
Finally, through the SMART NET system, the local network concept is revolutionised, increasing energy savings
and safety compared to older systems.

ACTIVE CONTROL OF OPERATING CONDITIONS
The SMART COOL system allows the display and monitoring of the operating
conditions of the whole cooling cycle, from both the local display and the supervision
systems as well as building management systems (BMS).
Using suitable probes and pressure transducers, the following quantities are detected:
1)Evaporation pressure and temperature of the refrigerant in the evaporator.
2)Refrigerant temperature aspirated (suction) by the compressor.
3) Temperature of the supply line refrigerant (discharge) from the compressor.
4)Condensing pressure and temperature of the refrigerant in the condenser.
5) Temperature of the outgoing liquid refrigerant from the condenser.
The following values are calculated from these figures:
A)Superheat of the refrigerant (SH).
B)De-superheat of the refrigerant (DSH).
C)Subcooling of the refrigerant (SC).
If a DC inverter compressor is installed, the following values will also be monitored:
• Actual speed in hertz (Hz)
• Electrical power consumption in amps (A)
• Power draw in kilowatt (kW)
OPERATIONAL SAFETY
The SMART COOL system actively manages 10 different safety function, designed to
provide high operational safety:
• Low evaporation pressure of the circuit (Low Pressure - LP)
• High condensing pressure of the circuit (High Pressure - HP)
• Low operating pressure of the circuit (LOP)
• High operating pressure of the circuit (Maximum Operating Pressure - MOP)
• Compressor low compression ratio (LCR)
• Low superheat value (LoSH)
• High superheat value (HiSH)
• Low de-superheat value (LDSH)
• High de-superheat value (HDSH)
• Refrigerant high discharge temperature (HDT)
TOOL-LESS SIMPLIFIED MAINTENANCE
The SMART COOL system makes it possible to significantly simplify all the installation
and maintenance procedures of direct expansion units.
Using tools to check the conditions of the cooling circuit will be no longer necessary;
technicians will be able to easily access all the operating conditions by simply
pressing a button on the display.
Thanks to the ability to interface with the major supervision systems and building
management systems (BMS), monitoring the entire cycle of a unit will be even easier
and quicker.
19
FOCUS ON
THE INTELLIGENT LOCAL NETWORK
The units of the TECNAIR LV close control air conditioning range are equipped with an innovative control
system in a local network (LAN) which allows them to be managed and serviced more easily while improving
operational safety.
ACTIVE DISTRIBUTION OF WORKLOAD
The innovative SMART NET system allows the concept of local network to be revolutionized. Taking advantage
of the modulation capabilities of its components, this system makes it possible to actively share the workload
among all the units in the local network.
Compared to the latent redundancy Duty / Stand-by (n+1 or n+n) system, where the backup units were
stationary waiting for the onset of a problem, the SMART NET system allows the units connected to the
network to be kept always active.

EFFICIENCY AND ENERGY SAVING
Thanks to the distribution of workload, system efficiency can be increased by partialising the request to the
main components such as fans, compressors, electric batteries and humidifiers.
This partialisation directly translates into an energy saving of up to 60% compared to redundant-type networks
(n+1 or n+n). Indeed, instead of having active units working at 100% of their performance while one or several
machines are stationary, the SMART NET system allows the entire group of units to operate at 50 or 60% of the
their maximum load.
A SAFE AND RELIABLE NETWORK
The previous generation of latent redundancy systems gave control to a single unit (Master), while the other
units were passive (Slaves).
With a view to maximising the safety of the units operating in the network, the SMART NET system has been
developed with a MULTIMASTER management logic. In the MULTIMASTER system, each unit is able to take
control of the local network even if communication among units is defective (broken or damaged cable), or
in the case of shutdown of one of the units.

FOCUS ON
HIGH ENERGY SAVING AIR CONDITIONING UNIT
Using renewable energy sources is required to reduce the environmental impact of systems. TECNAIR LV has
developed innovative FREE COOLING systems able to achieve energy savings of over 50% compared to a
conventional air conditioner.
FREE COOLING FROM RENEWABLE SOURCES
Using outside air to cool environments is the primary source of energy savings available in temperate climate
areas.
Mild climate
TECNAIR LV has therefore decided to invest in the development of FREE COOLING close control air
conditioning units, able to ensure high energy savings combined with the efficiency and reliability that
distinguish this type of product.
INTELLIGENT ENERGY SAVING
The high number of hours per year in which FREE COOLING systems can be used ensures that the air
conditioning system energy consumption can be reduced by over 50%.
This is reflected in an immediate environmental sustainability increase, thanks to a significant reduction in
CO2 emissions, and the system operating costs.

INDIRECT FREE COOLING
The indirect FREE COOLING system is characterised by a hybrid unit, consisting of a primary water circuit
and a secondary direct expansion or chilled water circuit. The primary water circuit is connected to a dry
cooler that uses outside air - a source of renewable energy - to cool water. The secondary circuit on the other
hand exploits the mechanical cooling.
OPTIMISED OPERATING PROCEDURES
Depending on the outside air temperatures, three possible operating
procedures are possible:
TOTAL FREE COOLING
The unit completely operates in FREE COOLING without
triggering mechanical cooling.
PARTIAL FREE COOLING
In addition to operating the FREE COOLING circuit, mechanical
cooling can be triggered for the time strictly necessary to meet
the demand for cooling.
NO FREE COOLING
Regulation is completely entrusted to mechanical cooling,
excluding the FREE COOLING circuit.
SELF-ADAPTIVE SET-POINT OF THE DRY COOLER
In order to maximise the efficiency of the FREE COOLING system, the unit can handle the regulation of the
dry cooler coupled to it directly. Thanks to the self-adaptive set-point function, the fan speed can be regulated
so that the water always has a temperature consistent with the outside air
conditions.
This leads to an increase in the system efficiency, allowing you to maximise the
performance of both the FREE COOLING circuit and the direct expansion
circuit, ensuring low condensing temperatures. In addition, the fans of the dry
cooler will partially operate even with high temperatures, thereby increasing
the energy savings of the system.
23
FOCUS ON
DUAL CIRCUIT SYSTEM
Some critical applications require safety devices that prevent discontinuity of operation due to system
problems. TECNAIR LV has developed specific units, named TWO SOURCES, provided with two totally
independent cooling sources.
HIGH OPERATIONAL SAFETY
In an air conditioning system, the main cooling source may be insufficient to guarantee suitable environmental
conditions. This may be due to an overload of the system, maintenance, possible seasonal closures or any type
of emergency that may arise.
A reduction in the machine cooling capacity can lead to great instability in the system, reducing the ability to
control the system thermo-hygrometric conditions, even in the presence of redundancy or SMART NET
systems.
So as to avoid these problems, specific TWO SOURCES (TS) units have been developed providing a second
source of cooling, complete with its own control valve and totally independent from the primary one.
24
A SAFE, FLEXIBLE SYSTEM
The Two Sources system is very flexible and allows three different
types of systems:
CHILLED WATER + DIRECT EXPANSION TWO
SOURCES
The chilled water primary source of the unit is connected to a
building chiller or to District Cooling, whereas the secondary,
emergency, and direct expansion one is connected to remote air
or in-built water condensers.
DIRECT EXPANSION + CHILLED WATER TWO
SOURCES
The direct expansion primary source of the unit is connected to
remote air or in-built water condensers, whereas the secondary,
emergency, and water one is connected to a dedicated chiller, to
a groundwater/aqueduct water distribution network or to District
Cooling.
CHILLED WATER + CHILLED WATER TWO
SOURCES
Both sources of the unit are chilled water coils. The primary one
is normally connected to a building chiller or to District Cooling.
The emergency source can be connected to a dedicated chiller or
a groundwater/aqueduct water distribution network.
25
The P Series close control air conditioners have constructional and operating characteristics suitable for
environments where thermal loads of a sensitive nature prevail.
26
CLOSE CONTROL AIR CONDITIONERS
Although optimised for data centers, the technical characteristics of the P series make these units suitable for
various types of special applications, such as metrology laboratories, TV production studios, recording and
conservation rooms for musical instruments, museums and archives, control rooms in power stations and
railway junctions.

G series close control air conditioners have constructional and operating characteristics suitable for meeting
the design criteria of the latest generation data centers.

CLOSE CONTROL AIR CONDITIONERS FOR LARGE DATA CENTERS
When designing air conditioning systems for large data centers, the need for electrical cable housing and the
enormous air volumes required to cool down the servers have made it essential to increase the height of raised
floors up to the current 550/1,000-millimetre level. A large space below the air conditioner for the installation
of an adjustable stand has thus created. It was therefore decided to use this large space to house supply fans.
Without increasing the footprint of the machine, and only exploiting space where it is provided, great
advantages have been obtained:
• With the same air conditioner footprint, it has been possible to increase the front section of the coil by about
40-50% by reducing the pressure drop on the air side, and thus the fan energy consumption.
• Increasing the size of the air filters installed upstream of the cold coil allows a significant reduction in load
losses and replacement frequency for maintenance.
• Increased efficiency of the fans which, installed in the stand, expel treated air horizontally and completely
unobstructedly.
GENERAL FEATURES
• Very high EER (Energy Efficiency Ratio)
• Limited footprint
• Dark gray RAL 7024 metal structure
• Panels with thermo-acoustic insulation
• Electrical panel complete with control and safety devices
• SURVEYEVO control microprocessor with graphic display

R series close control air conditioners are built and sized in such a way that they can be installed alongside
data center racks.
36
CLOSE CONTROL AIR CONDITIONERS FOR “IN ROW” INSTALLATION
In air conditioning systems for large data centers, the adoption of the following design concepts has in fact
become an established custom:
• The racks containing servers are increasingly positioned according to the Hot Aisle and Cold Aisle layout.
• Air temperatures are allowed to rise up to 30-35°C in the hot aisle and 20-25°C in the cold one, with very
low humidity (never above 30%).
• Server performance is increasingly on the rise, while server sizes are increasingly reduced. As a result, many
more servers can be installed in a rack, so some of these racks can be eliminated as they are empty. At the
same time, heat dissipation increases, thereby requiring more power from air conditioners.
R series air conditioners are designed and built so as to fit into this plant layout perfectly. As a matter of fact:
• They exploit the space left free from racks and allow cold air to be distributed as close as possible to servers,
that is, where heat is generated.
• They feature rear intake from the hot aisle and front supply to the cold aisle with a horizontal flow. The
horizontal flow reduces internal pressure drop, with a consequent reduction in the power draw of the fan.
GENERAL FEATURES
• Very high EER (Energy Efficiency Ratio)
• Limited footprint
• Dark gray RAL 7024 metal structure
• Panels with thermo-acoustic insulation

F series close control air conditioners exploit the indirect FREE COOLING system with adiabatic cooling to
ensure high system energy savings.
40
FREE COOLING AIR CONDITIONERS WITH ADIABATIC COOLING
The F series units are the ideal solution to cool air in systems where environmental sustainability and energy
savings are priorities, such as large, latest generation data centers, ensuring a performance similar to direct
FREE COOLING without however contaminating air-conditioned premises, as outside air contains pollutants,
dust, and humidity.
The units are designed to be installed outdoors, typically on the roof, and consist of two treatment sections,
one for inside air and another for outside air, physically separated and with two completely independent
filtering and ventilating sections.
GENERAL FEATURES
• EUROVENT certified plate heat exchanger
• OXYVAP® evaporative panel
• White RAL 9010 metal structure
• Panels with 50-mm thermal and acoustic insulation
• G4-class efficiency air filters with dirty filter alert
•Electronic EC FANS
• Electric panel complete with control and safety devices
• SURVEYEVO control microprocessor with graphic display
• Unit shutdown system for the presence of fire
• RS485 Modbus® RTU slave card
• RJ45 ethernet card
41
INDIRECT FREE COOLING WITH ADIABATIC COOLING
The indirect FREE COOLING system with adiabatic cooling includes both the technology of air-to-air heat
recovery and that of the adiabatic cooling, in which some water is evaporated to cool down outside air.
Being able to exploit the FREE COOLING system even at external temperatures of 30°C/35%Rh, these units
can achiever very high energy efficiency and energy savings of over 80% compared to a mechanical cooling
system.
AN INNOVATIVE EVAPORATIVE PANEL
In order to maximise the system efficiency, TECNAIR LV uses an innovative evaporative panel that allows
saturation efficiency greater than 90% using more than 60% less water.
Thanks to the OXYVAP® system, formed by special aluminium fins treated to retain water, it is possible to:
• Use drinking water. No expensive water demineralisation systems, indispensable in conventional spraying
systems, are required.
• Cut down on water consumption. An over 60% water reduction compared to conventional evaporative
panels and spraying systems.
• Eliminate the risk of the formation of mould, algae and pathogenic organisms. The surface treatment of
aluminium fins and the absence of a collection and water circulation tank eliminates the risk of pathogenic
organism formation.
EUROVENT CERTIFIED HEAT EXCHANGER
The air-to-air plate heat exchangers allow heat to be transferred from one flow to another under the action of
a temperature difference. Their design allows for higher reliability of the unit and easier maintenance, as these
exchangers have no moving parts and are easy to clean.
TECNAIR LV uses certified EUROVENT plate heat exchangers to ensure optimum performance and reliability,
thanks to independent tests that confirm their validity.

FREE COOLING AIR CONDITIONERS WITH ADIABATIC COOLING
SPECIFIC SURVEYEVO CONTROL SOFTWARE
TECNAIR LV has developed a specific software based on SURVEYEVO hardware which allows the combination
of close control advanced functions with those needed to optimise the FREE COOLING system control.
Thanks to the integrated Ethernet card, units can be supervised via specific web pages while being regularly
interfaced with supervision and building management systems (BMS).
ENHANCED OPERATING MODES
The units with indirect FREE COOLING system and adiabatic cooling can work in three operating modes:
WINTER MODE
During the winter period, units exploit the plate
heat exchanger to cool down the air coming
from the system. The outside air flow is adjusted
to provide the cooling capacity needed to cool
down the system, thus optimising efficiency
and energy savings. The air flow to the system is
kept constant by managing the air flow rate or
the environment pressure.
Outside
air
System
air
Outside
air
System

Outside

System

SUMMER MODE
During the summer period, the evaporative
panel is enabled. This, by saturating the outside
air flow, reduces the temperature thereof. This
allows you to continue to exploit the plate heat
exchanger to cool down the air coming from
the system. The outside air flow and the
activation of the evaporative panel are adjusted
to provide the cooling capacity needed to cool
down the system, thus optimising efficiency
and energy savings. The air flow to the system is
kept constant by managing the air flow rate or
the environment pressure.
SUPPLEMENTARY POST COOLING
Under extreme external conditions, it is possible
to install a supplementary post cooling circuit
which allows you to further cool down the air
already treated by the plate heat exchanger ,
keeping the heat and humidity conditions
required by the system. This can be a direct
expansion or a chilled water supplementary
circuit.

OUR SOLUTIONS FOR DATA CENTERS
The units of the TECNAIR LV close control air
conditioning range have been optimised for
use in new generation data centers, offering
the highest guarantee of flexibility, efficiency
and reliability.
Technological progress has created the need
for ever greater exchange of data, thereby
exponentially increasing the concentration of
electronic equipment in data centers.
Infrastructure limits and constantly growing
energy costs have thus redefined the design
and development standards of data centers,
making efficiency and energy saving key
concepts underlying the choice of close
control air conditioners.

MEDIUM
< 10 kW/rack

Density
Density
Low-density data centers are normally configured
according to the hot/cold aisle design.
This type of system involves the use of perimetral
units which, through a raised floor, convey air
into the “cold aisle”.
The air heated by servers is then collected by
“hot aisles”.
This solution offers high flexibility, making it easy
to enlarge a data center over time, as well as
changing the rack arrangement.
48
HIGH
Density
> 20 kW/rack
High-density data centers are normally configured
according to the hot/cold aisle partitioning design,
with any localised, “in-row” air conditioning units.
Medium-density data centers are normally
configured according to the hot/cold aisle
design and adding localised “in-row” air
conditioning units.
This type of system involves the use of highefficiency perimetral units, with ventilation being
installed in the raised floor. The rack aisles (hot or
cold) are partitioned to prevent hot and cold water
from being mixed and obtain homogeneous
distribution on the servers. “In-row” units allow
you to add a localised temperature control, which
eliminates “hot-spot” problems.
This type of system involves the use of perimetral
units which, through a raised floor, convey air
into the “cold aisle”. The air heated by racks will
then be collected by hot aisles.
“In-row” units allow you to add a localised
temperature control, which eliminates “hot-spot”
problems.
This solution allows you to optimise air distribution
and maximize the system energy efficiency,
avoiding energy waste due to mixing hot and cold
air in the upper part of the racks.
This solution is optimal both if an existing data
center is expanded, and for the optimisation of
loads in newly implemented data centers.
