Description

FEATURES

R22 screw water chiller has 34 sizes available ranging from 180 kW to 4120 kW cooling capacity.

Screw water chiller Wide application as hotel, apartment, villa, factory, shopping center, office building, school, etc.

R22 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 the discharge line.

Big screw chiller The refrigerant circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, direct expansion valve, high and low pressure switch.

Shell and tube dry expansion type condenser, factory insulated with flexible close cell material.

Shell and tube type evaporator FUSHENG/Bitzer/Hanbell screw compressor

Water to water Screw chiller 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.

Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor 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.

OPTIONAL

Electronic expansion valve

Heat recovery as optional.

Electronic controller with BMS system.

Low noise compressor cabinet or outside full cover

Channel Steel base
