Feature
1. Twin screw compressors of world famous brand is adopted, with high efficiency, low noise level, less wearing and long operation time.
2. The unit is of high performance as they are made of the condensers and evaporators of grooved copper pipes, and high quality components,
by specialized process.
3.The unit is easy to operate, and friendly interfaced, as they adopt leading brand PLC, 64K color touch screen and other control elements.
4.The energy saving for Multi-capacity regulation, resulted in cost cut down for operation and maintenance.
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 protection:It protects the compressor for over high voltage, voltage dificiency, and phase lack.
3. Direction protection:It protects the compressor from damage resulted 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 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,the temperature of chilled water is too high. It may result in compressor failure without this protect in the case.
