    ■ 40 sizes available ranging from 450kW to 4000 kW cooling capacity, with heat recovery and low temperature output;

    ■Semi-hermetic screw compressor for all models. Each compressor is equipped with a

    crankcase heater and a thermal overload cut-out,the screw compressor is also complete with a built-in electronic protection with temperature sensor located directly in the motor winding and on discharge line;

    ■The refrigerant circuit is complete with sight glass, filter drier, high&low pressure gauges, solenoid valve, direct expansion valve, high and low pressure switch;

    ■ Shell and tube heat exchanger,,factory insulated with flexible close cell material;

    ■ The electric panel consists of compressor breaker, compressor contactor, phase sequence relay, control circuit breaker, microprocessor control with function display.

    ■ Automatic operation dramatically reducing maintenance cost thanks to reliable micro-processor system;

    ■ For the units with semi-hermetic screw compressor, an infinitely variable capacity control system that is capable of exactly matching the demand requirement of the system is to be supplied. This system is to provide precise and stable control of supply water temperature over the complete range of operating conditions.
