Features
1.  30 sizes available rang ing from 100 kW to 1600 kW cooling capacity.
2. Wide application as hotel, apartment, villa, factory, shopping center, office building, school, etc.
3. Semi- hermetic screw compress or 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.
4. 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.
5.  Shell and tube dry expansion type condenser, factory insulated with flexible close cell material.
6. The electric panel consists of compressor breaker, compressor contactor, phase sequence relay , control circuit breaker, microprocessor control with function display.
7. LCD display, touch screen control panel as standard.
8. Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.
9. For the units with semi-hermetic screw compressor, an infinitely variable capacit y 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.
System Control
1.  Imaged system operation chart, showing the temperature of water in /out, the energy level of compressor run, on/off button, run time, alarm etc .And the remote turn on/off function is available. PC remote control is optional.
2.  Notice for maintenance is indicated according to the accumulated run time of the compressor.It is convenience to maintenance.
3. The control system will automatically balance the run time for each compressor for mult-compressor unit.
Safety Protections
1. Discharge check value:it prevents the discharged gas from going back after the compressor stops.
2. Phase lack prot ection:It protects the compressor for over high voltage , voltage dificiency, and phase lack.
3. D irection prot ection:It pro tects the compressor from damage resul ted from Counter direction run.
4. Oil heater : It heats the oil before the unit start, keep the good lubrication for the unit before it runs.
5. Overheat protection in side the motor of the compressor: It protects the compressor from burni ng d ow n for too high coil
tem per ature for ove rload, or a bno rmal run condition.
6. H igh&low pressure prot ection:It pro tects the compressor and system against extreme run condition and trouble.
7.  Freezing protection:It protects the unit form too low temperature of the water out, freezing may occerat some place,resulting in freezing bre akin g of the evaporator.
8. Wa ter flow p rotect:It pro tects the u nit from run witho ut water flow.
9. High tem pe rature o f chill ed water pr ote ction: It works to pr otect the com p resso r in case that the load is too large,the temperature
o f chilled wa ter is too high . It may result in compressor failure without this  rotect in the case.
