Operation

DBO single blocks are compression units where cold is produced by vaporizing a liquid refrigerant (HFC
type) at low pressure in a heat exchanger (evaporator). The resulting vapour is brought again into the liquid state
by mechanical compression at a higher pressure, followed by cooling in another heat exchanger (condenser).
The compressor is hermetic, with reciprocating motion, supplied with single-phase or three-phase power.
Defrost takes place automatically in pre-set cycles, by means of heaters; manual defrost is also possible.
