Description
The system has been designed to teach a methodical approach to faultfinding in an industrial process. This self-contained refrigeration unit is made from industrial standard components.The design allows practical instruction to be given on methods of identifying and correcting faults in industrial systems, in exactly the same way as experienced in field service conditions. The system consists of a mobile, floor-standing process unit comprising a twin cylinder semi-hermetic compressor, finned-tube condenser with fan, liquid receiver and forced air evaporator. All the above are mounted on a common base plate for easy access. 39-103 is 220/240V, 50Hz. 39-104 is 110/120V, 60Hz.
