3. DESCRIPTION OF THE UNIT

The SP series includes air-cooled or water-cooled (optional) condensing units built in split version. They
consist of:

4. OPERATION

SP 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.

5. HANDLING

The unit can be handled by lifting and transport means.
WARNING
Make sure that no one is in transit in the operating area of the lifting/ transport means to
prevent any possible accidents to people.
