Industrial Water Cooled Glycol Water Chillers/Cooling System

Semi-hermetic screw compressor for the whole range, each compressor is equipped with a crankcase heater and a built-in electronic protection with temperature sensor located directly in the motor winding and on the discharge line. The refrigerant circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, electronic expansion valve, high and low pressure switch.

Shell and tube dry expansion type condenser. Shell and tube type evaporator, higher efficiency less water consumption, easy maintenance and cleaning, 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. LCD display, touch screen control panel as standard.

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.
