Water chiller / air-cooled / screw compressor / semi-hermetic compressor

TECHNICAL DESCRIPTION
The Air cooled water chillers ESAC series EPSI are produced currently in 35 models for R22, R407C and R134a. The corresponding capacities range from 145kw up to 1387kw. They are ideal for fully proportional response to the cooling load of Air Conditioning Installations (i.e. Commercial Buildings, Hotels, Hospitals, etc) Also they could cover fully proportionally to the load of industrial application, where chiller water may be required to go down to +4°C.
Unit Housing : it consists of galvanized steel sheets 2,5mm thickness that provide substantial rigidity and durability. Furthermore it's coated externally with epoxy powder for compleate weather protection against corrosion.
Compressors : are semi-hermetic twin screw type, and having the following 3 parts in a single casing. Two poles suction gas cooled motor, internally by thermo couple protected against overheating which drives directly the male rotor. Additional thermocouple located at the discharge of the compressor, protects the motor against overheating. Twin screw with SLIDE VALVE fully analogue capacity control, filter and electrical oil heater. Flanged on oil separator, without any oil piping, oil pumps and other additional components, usually required when the separator is not incorporated within the main body of the compressor.
The single casing arrangement assurers minimum oil quantity outside the compressor and maintenance simplicity.
