Operation

SB single blocks
(Hydrocarbon R290 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 semihermetic, with reciprocating motion, supplied with single-phase or three-phase power.
Defrost takes place automatically in pre-set cycles; manual defrost is also possible.
