• Innovation is our forte and we strive to design and develop a precision engineered range of highly efficient Cold Room Controllers. 
• This CRC-1100A is a panel mounted controller and is efficient in controlling the cold room temperature. There is a controller present in these freezers, which effectively controls the defrost. 
• It does so either with the aid of an electrical heater where the compressor is stopped or at cycle inversion using warm gas where the compressor keeps on working.
•  Intervals between defrosts and the maximum time out after which the defrost needs to be interrupted can be decided by the user.
•  Evaporator fans present in the freezer are controlled by the same probe which controls the defrost cycle.

Other Details:

• Possible to set the temperature
• Delay time after a defrost can also be set
• User can also decide the relation of fans with the compressor

Main Features:

• LCD with back lighting to display all parameters
• 2 NTC probes for cold room temp + evap. coil temperature
• Relay outputs : Compressor + Cond. Fan + Heater + Evap. Fan + Alarm
• Audible alarm. •Digital inputs : 2 nos. (a) Door switch (b) Pressure cutout
• HP / LP / OSS trip protection for compressor. •Compressor protection algorithm
• Auto/Manual defrosting facility (Time/Temp based)
• Special software to indicate probable heater fault

Input & Output:

• Relay Output 1 : 8(3)A Compressor
