IR33 REFRIGERATION CONTROLLER | |
![]() |
The Carel IR33 series temperature controllers are designed specifically for refrigeration and food processing applications. The IR33 represents the evolution of the IR32 range and can be used as a straight replacement although many new features have been incorporated. All types have 2 NTC sensor inputs for ambient and defrost temperatures (PTC input types are also available), ideal for operation over the temperature range -50 to +150ºC. The model range provides flexibility in controlling refrigeration units with compressor, evaporator fan and defrost management. Versions are available with a built in real time clock and HACCP management functions. For ease of set up, the unit can be programmed via a PC, using the infra red hand held programmer or via the optional programming key.
