water cooled water chiller, geothermal water chiller, screw compressor, single or double compressor

Water chiller, screw compressor, for 7, -5 or -15 celcius degree water cooling: 80 to 1647kW for water source, or geothermal

Screw compressor water chiller

We produce following types of screw compressor  water source water chiller: 

1. Minimum Chilled water out 7oC, single screw compressor, 100kW to 825kW.

2. Minimum Chilled water out 7oC, double screw compressor, 200kW to 1647kW.

3. Minimum Chilled water out 7oC, single screw compressor, with heat recovery, 100kW to 825kW.

4. Minimum Chilled water out 7oC, double screw compressor, with heat recovery, (200kW to 1647kW).

5. Minimum Chilled water out -5oC, single screw compressor, 55kW to 466kW.

6. Minimum Chilled water out -5oC,, double screw compressor, 110kW to 932kW.

7. Minimum Chilled water out -15oC, single screw compressor, 42kW to 351kW.

8. Minimum Chilled water out -15oC,double screw compressor, 84 to 702kW.

Features:

1) Adopt Hitachi compressor, high efficiency, low noise, less wearing and long life.

2) Both Evaporator and Condenser are made of grooved copper pipes.

3) Adopt leading brand PLC, 64K color touch screen etc. user friendly and easy operation.

4) Multi-capacity regulation, energy saving, cost cut down greatly for operation and maintenance.

System Control:

1) System working display, showing the temperature of water in/out, the energy level of running compressor, on/off button, run time, alarm etc. Remote turn on/off function is available. PC remote control is optional.

2) Accumulated running time of compressor will be displayed, it's convenient for maintenance.

3) For two compressor unit, it can detect each compressor's working status and balance it's working time.

SAFETY PROTECTION:

1. Discharge check value: it prevents the discharged gas from going back after the compressor stopped.

2. Phase lack protection: It protects the compressor for over high voltage, voltage deficiency, and phase lack.

3. Direction protection: It protects the compressor from damage resulted from reverse 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 inside the motor of the compressor: It protects the compressor from burning down for too high coil temperature for overload, or abnormal run condition.

6. High&low pressure protection: It protects 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 breaking of the evaporator.

8. Water flow protect: It protects the unit from run without water flow.

9. High temperature of chilled water protection: It works to protect the compressor in case that the load is too large and chilled water's temperature cannot cool down, It may result in compressor failure without this protect in the case.
