Capacity: 110÷3800 KW

Refrigerant：R134a

High energy efficiency（Flooded type exchanger）

FEATURES

• 20 sizes available ranging from 110kW to 3800kW cooling capacity.

• Wide application as hotel, apartment, villa, factory, shopping center, office building, school, etc.

• Hermetic scroll compressor and semi-hermetic screw compressor, 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.

• 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.

• 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 requirement of the system. This system is to provide precise and stable control of supply water temperature over the complete range of operating conditions.

Optional

• Electronic expansion valve.

• Electronic controller with BMS system.
