COMPRESSOR
Hermetic scroll complete with internal thermal protection.The compressor is isolated from the structure by interposition of special rubber mountings. The mobile spiral is driven by an electric motor 2-pole (2900 rpm) cooled by the inlet refrigerant, the starter is directed. All compressors have full charge of oil polyester, suitable for use with refrigerant R410A. An electrical heater, located on the crankcase, is automatically activated when the unit is switch off in order to prevent the mixing of oil in the refrigerant. The control of cooling power is achieved through steps of parzialization in number equal to the number of compressors installed. When connecting in tandem there is an oil equalizing line with a level indicator.

CARPENTRY
Suitable for outdoor installation.

USER (SIDE) HEAT EXCHANGER
AISI 304 steel braze-welded plate exchanger, insulated with Black closed-cell flexible elastomeric foam (FEF) coupled with a 3 mm layer of reticulated foam in PE and an exterior embossed finishing PE film in aluminium in colour.
Maximum operating pressure exchanger: 15 bar on the water side and 45 bar on the refrigerant side.
