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.

If you need the unit
with the evaporator or condenser whose permitted pressure is more than
1.4/1.9MPa, please contact with us
The capacity control
type can be stepless one.If you need, please confirm this point in the
technical requirement.Its control range is 25%~100%.
The noise level will
be measured in the third octave band limited values, using a Real Time Analyser
calibrated sound intensity meter. The noise level is measured at 2meter in
front of the unit, 2 meter high to the ground.

If you need the unit
with the evaporator or condenser whose permitted pressure is more than
1.4/1.9MPa, please contact with us
The capacity control
type can be stepless one.If you need, please confirm this point in the
technical requirement.Its control range is 25%~100%.
The noise level will
be measured in the third octave band limited values, using a Real Time Analyser
calibrated sound intensity meter. The noise level is measured at 2meter in
front of the unit, 2 meter high to the ground.
