Application Field
WESTRIC IW precision air handling units have been developed to be installed in rack computing centers to act directly on
the hot spots, and save energy thanks to their EC fans.
Its function is to control the temperature and humidity of the racks 24/7, making decisions in order to maintain at all times,
the programmed conditions
General features
IW units are manufactured using galvanized, pre-painted steel sheets, ensuring a long service life of the cabinet housing
without the need of repainting or other maintenance procedures.
To enable its cooling operation under low outdoor temperatures, WESTRIC air conditioners with air-cooled condensation
are equipped with electronically-controlled modulating condensation, allowing complete control of the operating conditions.
The evaporator section has a large coil and a high air flow which ensure high performance under sensible heat.
The electrical heaters accelerate the dehumidifying process by reheating the air.
Stainless steel drain pan. Stainless steel made, collects the condensate and funnels it to the drain line
Deshumidification. In case dehumidification is necessary, this will be done by reducing the fan speed of the air
handling unit. This function acts automatically thanks to variable capacity EC fans and factory programming.
Air Filters. 30/30 medium-efficiency filters ensuring the cleanliness of air circulating through the evaporator.
EC Fans. High efficiency EC fans, modulate their speed through the controller to obtain the necessary air flow for each
moment of the refrigeration cycle, in this way they increase the energy saving.
Clogged-Air Filter Switch This device acts when the accumulated dirt on the filter decreases the air flow, which is
transmitted to the controller, the system first gives a warning alarm and if the filters is not replaced the controller leaves
the unit out of service, this causes the units in the same network increases its flow to try to replace the out of order unit.
Klixon Thermal Protections. This thermal protector will disconnect the heating system in case of blower motor failure.
Each set of resistors has its own independent protection.
Electric heater for heating Their electrical output is practically equivalent to the one of the compressor, so that power
consumption during cooling or heating operations is the same.
WARNING
- THIS APPLIANCE IS NOT DESIGNED FOR USE BY PERSONS, INCLUDING CHILDREN, WITH REDUCED PHYSICAL,
SENSORY OR MENTAL CAPACITIES, OR LACK OF EXPERIENCE AND KNOWLEDGE, UNLESS THEY HAVE BEEN
SUPERVISED OR INSTRUCTED ABOUT THE USE OF THE APPLIANCE BY PERSONS RESPONSIBLE FOR THEIR USE
SECURITY.
- CHILDREN MUST BE SUPERVISED TO ENSURE THAT THEY DO NOT PLAY WITH THE APPLIANCE
- THIS UNIT MUST BE INSTALLED ACCORDING TO NATIONAL, STATE AND / OR MUNICIPAL SAFETY REGULATIONS

Control Panel
The units are controlled by a built-in panel. The panel houses the controller, which are connected to other units via
interconnection terminals.
Therefore, the operation of the unit is entirely automatic.
The controller has a Flash memory which records the operating program and it also has multiple inputs and outputs. The
unit receives data from sensors and controls different elements of the system.
Using the display and keypad built into the controller makes it possible not only to obtain data about the conditions in the
room, but also the fault data log. Using an access code or password the user can enter the menu to change temperature
or humidity set points, cycling parameters, etc.
The control panel is able to receive the signal from a power-free contact from a fire control room; this signal is used to
switch off the units in case the fire alarm is triggered.
Main elements of unit panel:
Microprocessed controller
Power Supply Transformer
General circuit breaker
Air inlet/outlet temperatura sensors
Relative Humidity Sensor
Phase monitoring relay
Terminal blocks
Controller. Each system is controlled by a dedicated controller for air conditioners.
Temperature sensor. This sensor sends information to the Controller about changes in room temperature.
Humidity sensor. This sensor sends analog information to the Controller about changes in room humidity.
Controller alarm outputs. The system has alarm outputs which are triggered when one or more units are out of
service.
Phase monitoring relay. This sensor is used to detect under- or overvoltage conditions, missing phase or phase
asymmetry.

Temperature and Humidity Working Range
WARNING: If the indoor humidity is too high, the condensation effect around the coil can generate too much
condensed water, which could cause a water spill or trigger an alarm.
Nota: If it is in a not operable condition, use an auxiliary dehumidifier or an air conditioner to adjust the interior
temperature and humidity until it falls within an acceptable operating rang
