The right solution for you
Standard
The WPA Techno range expands the series of high efficiency chillers for industrial, IT and comfort
applications, made by COSMOTEC.
WPA are chillers for outdoor installation, specifically designed to have high performance with small
footprint.
Efficiency, strength and reliability at COSMOTEC levels.
Low Noise
WPA Techno is a highly silenced unit, thanks to the adoption of acoustic insulations, specifically designed
and placed in the compressor compartment (ISO 3744).
In order to maximize the noise reduction the maximum speed of the fans is limitated.
The optimization of the coils/fans group allows to limit the cooling capacity reduction compared to the
standard version.
Available for all sizes of WPA Techno.
Free Cooling
The Free Cooling circuit is composed of air-water exchanger coils with copper tubes and aluminium fins.
A 3-ways valve is controlled by SEC.blue, to ensure the maximum yield, minimizing the compressor operation time and reducing the running costs.
There is a cataphoresis treatment on the condensing coils, in order to prevent corrosion due to stray
currents.
The total heat recovery from the ambient air is obtained at about 0°C: the entire cooling capacity is supplied by the Free Cooling batteries.
When the ambient temperature drops, the SEC.blue controller partialises even further the 3-ways valve
and the fans, guaranteeing the correct thermal load management.
Due to the need to maximize the air flow through the batteries, is not possible to combine Free Cooling to
the “Super Silent” version.
All versions have:
Gas R410A
All units of the WPA Techno range use refrigerant gas R410A, which ensures a higher cooling capacity
with low footprint of the machine.
The R410A assures a very low environmental impact, no impact on the ozone and a greenhouse gas coefficient lower than the usual refrigerants.
Outdoor installation
WPA Techno is designed to be used for every outdoor installation. The electrical panel, with IP54 protection, guarantees an adequate security for electric and electronic components.
The different options allow a further extension of the operating limits both at low and high temperatures,
with enhanced protection for highly corrosive environments.

Scroll Compressor
The Heart of the WPA Techno
Hermetic Scroll
The heart of the COSMOTEC Techno range are the hermetic scroll compressors, specifically designed for
air cooled refrigerant circuits. These compressors are able to compress all the ecological refrigerant gases used by COSMOTEC.
State of the art compressors, able to achieve high compression ratios with reduced consumption.
Thanks to the compressor double spiral system the gas is continuously compressed, allowing to maintain
the rotation inertia of the compressor motor, avoiding overloads, electrical consumption peaks, reducing
mechanical stresses, which are the primary cause of the reduction of the product life.
Starting
The starting of the compressors is direct with delta connection, and is managed by the electronic
controllers SEC.blue. The electronic controller starts the compressors in sequence, verifying the compliance with the timing imposed by the supplier and maintaining the operation hours aligned.

SEC.blue Electronic Control
The Mind
The “mind” of the COSMOTEC Techno chiller is the SEC.blue
electronic control, developed by COSMOTEC to achieve the
best performance from every component. New functions
have been implemented in the COSMOTEC Techno range
in order to obtain the best management of the new components. Memory and calculation speed are increased, allowing
a better and faster control of all the components and preserving the durability of the units.
The numerous functions and parameters are summarized in
a few simple steps and screens, which allow the user to easily
keep under control the chiller correct operation.
A 7” liquid crystal display with touch screen acts as an
interface between the user and the chiller. The display reports
all the information on: operation status, working time, alarm
history and alarm signals. Furthermore it allows to start, stop
and modify the chiller operation.
SEC.blue Electronic Controller is equipped
with the following pre-loaded functions:
ƒƒ Sequencing = to connect through a specific
line more chillers and manage the
components as a unique chiller
ƒƒ Emergency Cooling = to activate the chillers
in the same line, in case the active chiller
cannot make up for the overload of the user.
ƒƒ Redundancy = activates alternatively
the chillers and guarantees the service
continuity in case of fault of a chiller.
ƒƒ ModBus RTU = to manage remotely the chiller
through standard interfaces
ƒƒ STULZ Protocol = to connect the chiller to the
STULZ supervision components
ƒƒ Unloading = guarantees the chiller partialised
operation even at high temperatures
ƒƒ Antifreeze
20
SEC.blue Electronic Controller manages:
ƒƒ Compressors = start, switching off, within the
limits provided by the supplier
ƒƒ Fans = depending on the power requested
and on the active function (chiller, Free
Cooling) sets the fans speed, to guarantee
the maximum yield with lesser noise and
electric consumption
ƒƒ Electronic Thermostatic Valves = partialises
the refrigerant evaporation to obtain the
requested power with the lesser electrical
consumption
ƒƒ Fluid side pumps (where expected) = the
electronic control manages the redundancy
in case of installation of 2 pumps, in order
to maintain the working time of the pumps
assimilar as possible.
ƒƒ Free Cooling circuit = partialising the 3-ways
valve, it takes advantage of the entire cooling
capacity recoverable from the ambient air.
Low Noise
Silent, whenever needed
In the WPA Techno the noise can be made by the compressors and the air flow through the condensers. It’s possible to reduce the noise level (about -10 dB) selecting the Low Noise Version of WPA Techno.
The noise is reduced with the following solutions:
Fan speed reduction
To reduce the noise caused by the flow of the air through the exchangers, the fans speed is reduced
moving the electrical connections from Delta to Star.
This solution reduces the speed approximately about 30%. This requires a greater dimension of the
condenser coils to achieve the same cooling capacity of the standard version.
STANDARD version
FREE COOLING version
LOW NOISE version
880 rpm
670 rpm
0 rpm
Acoustic Isolation
In WPA Techno a textile fibre of polyester vane covers each compressor and the pumps.
The vane is made of a metal sheet powdered in the same colour of the chiller.
The vane allows the complete access to the compressors electrical box.
21
Free Cooling
Energy and Money saving
The Free Cooling circuit is composed of a coil with copper tubes and
aluminium fins. A 3-ways valve, controlled by the SEC.blue, ensures the
maximum yield, minimizing the compressor operation time and reducing
the running costs.
Cataphoresis treatment on the condensing coils, in order to prevent corrosion due to stray currents.
The total heat recovery from the ambient air is obtained at about 0°C: the
entire cooling capacity is supplied by the free cooling coils.
When the ambient temperature drops, the SEC.blue controller partialises even further the 3-ways valve and the fans, guaranteeing the correct
thermal load management.
Due to the need to maximize the air flow through the coils, is not possible to combine Free Cooling to the “Super Silent” version.
Summer Mode
During the summer the air temperature is
too high to exchange with the water, then the
3-way valve close the Free Cooling and the
water goes directly to the evaporator.
The chiller cools the water.
Mix Mode
The valves allow the passage of the water
through the Free Cooling coils to exchange
some heat. The rest of the heat is removed
by the chiller.
Due of the fact that the fans are managed
first to maximize the yield of the cooling circuit, if possible one cooling circuit is totally
turned off to maximize the Free Cooling
yield.
Winter Mode
When the temperature reaches about
0°C the cooling capacity of the Free Cooling coils is at the maximum. The chiller is stopped and the water heat is all
exchanged with the ambient air.
The energy is used only to run the fans.
That is the way to reduce a lot of energy
and the operating cost.
22
Temperate climate
In temperate climates north and south of the equatorial
zone, the energy-saving advantages of Indirect Free
Cooling can be fully exploited. Electricity consumption
for data center air conditioning will drop by up to 60%.
EER - ESEER - IPLV
Energy Efficient in every season
WPA Techno chillers are developed to cover an entire range of applications (from process industry to data centers).
The Techno units are designed for a high energy class (Class A or B) or to work in extreme environmental conditions.
They also come in very precise configurations with temperature controls dedicated to the application.
In almost all applications, the thermal load and ambient temperature conditions are highly variable. WPA Techno
units closely match all environmental and load conditions, achieving a high seasonal efficiency (ESEER) – even higher than 5. High ESEER values lead to significant energy savings.
EER: Energy Efficiency Ratio
The Energy Efficiency Ratio (EER) of a particular cooling device is the ratio of output cooling energy to
input electrical energy at a given operating point. EER is generally calculated using a 35°C outside air temperature and an inlet water temperature at 12 °C, outlet water temperature at 7°C.
EER = Cooling Capacity
W7L35
/ Power consuptionW7L35
ESEER: European Seasonal Energy Efficiency Ratio
The seasonal energy efficiency index is a parameter that indicates the seasonal efficiency of an air
conditioner or a refrigerator group. The parameter is defined by the Eurovent Certification Company.
ESEER = 0.03 x EER

+ 0.33 x EER75% + 0.41 x EER50% + 0.23 x EER25%
IPLV: Integrated Part Load Value
The Integrated Part Load Value (IPLV) is a performance characteristic developed by the Air-Conditioning,
Heating and Refrigeration Institute (AHRI). It is most commonly used to describe the performance of a
chiller capable of capacity modulation. Unlike an EER (Energy Efficiency Ratio) or COP (coefficient of performance), which describes the efficiency at full load conditions, the IPLV is derived from the equipment
efficiency while operating at various capacities.
IPLV = 0.01 x EER
