»» CRC-1100



The CRC-1100 is a panel mounted controller dedicated to controlling the cold room and its various devices.

The controller controls the defrost in the system based on either an electrical heater where the compressor is stopped, or at cycle inversion using warm gas where the compressor keeps on working.

It is also possible to select the interval between defrosts and a maximum time out after which the defrost is interrupted. The same probe which controls the defrost cycle is also used to control the evaporator fans. It is possible to set the temperature, the time delay time after a defrost and the relation of fans with the compressor.

There are safety features which include shutting down the system incase of a fault from a pressure control or similar device.

Main Feature:

LCD with backlighting to display all parameters.
2 NTC probes for cold room temp + evap. coil temperature.
Relay outputs : Compressor + Cond. Fan + Heater + Evap. Fan + Alarm.
