3 Product overview
3.1 Operational area
Control module for refrigeration with inputs for temperature or pressure sensors; for instance a speed
controller for fans can be controlled via the 0-10 V output. In addition, the adiabatic plant (spraying)
valves are controlled and the outside temperature is recorded.
3.2 Function
Application in combination with a speed controller (input 0 - 10 V) for fans.
The control modules from the UNIcon series (types CKG-3RVE and CKE-3ARV) for adiabatic control
take over the control of up to three servomotors for moistening along with the regulating functions
(temperature/ pressure). A performance improvement can be achieved in heat exchangers by mois-
tening the ambient air to get evaporative cold (
examples of applications).
It is possible to switch off the regulation function (temperature or pressure), e.g. for retrofitting in an
existing plant. The device then only takes over the adiabatic function for triggering and monitoring the
spraying depending on the fan-modulation. In this case, an external controller (e.g. PXDM, FXDM)
supplies the control signal (0-10V) to the control module.
Because it is ideal when the spraying is switched on not before the fans already runnig with full speed,
the switch on of the steps can take place at free adjustable temperatures (alternative pressure). End
position switches can be connected to the digital inputs for controlling whether the valves are complete
opened by the servomotors.

To prevent frost damages the relays can control the water supply and the draining depending on
outdoor temperature. For complete draining of the system the relays responsible for spraying can also
be switched depending on outdoor temperature to prevent freezing.

Information
Simple installation is possible through the selection of the preprogrammed mode of operation.
This determines the basic function of the device, factory setting 2.01 temperature controller.
The controller is configured automatically when selecting the application-related modes. The
factory settings per mode are based on values gained in long years of experience which are
suitable for many applications. These can be adapted individually in exceptional cases (
Controller Setup: “Controller Setup”).
The purpose of the device is to reach and maintain the target values set. To accomplish this, the
measured actual value (sensor value) is compared with the adjusted target value, and the controlled
value (modulation) is deduced from this.
