HPM refrigeration systems are an excellent choice for medium and large supermarkets that demand high efficiency along with compact size, silent running and low purchase, running and maintenance costs. The frame is in galvanised and painted steel, the compressors are of the semi-hermetic reciprocating type, and the electric power panel incorporates an electronic controller that commands the entire system. An electro-mechanical backup unit is available to keep the system functioning in the event of a failure in the electronic controller, guaranteeing safe operation until the necessary repairs can be made.
