Features1. 24 sizes available ranging from 80 kW to 1000 kW cooling capacity;2. Semi-hermetic screw compressor 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 the discharge line;3. External rotor type axial fans, equipped with three phase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille;4. Evaporator built with high efficiency shell and tube type heat exchanger, factory insulated with flexible close cell material;5. Condenser built with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins;6. Refrigerant circuit complete with charge valves, filter drier, sight glass, gas-liquid separator, thermostatic expansion valve, high & low pressure switch. The heat pump unit is completed also with 4-way valve, liquid receiver and one way valve;7. Hydraulic circuit built with galvanized pipe, complete with water discharge connection for shell and tube heat exchanger and flange type hydraulic connectors;8. Electric panel consist of: compressor contactor, fan motor contactor, compressor isolating switch, fan protection breaker, phase sequence relay and microprocessor with function display.9. Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.System Control1. 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.4. Safety Protections5. Discharge check value:it prevents the discharged gas from going back after the compressor stops.6. Phase lack protection:It protects the compressor for over high voltage, voltage dificiency, and phase lack.7. Direction protection:It protects the compressor from damage resulted from Counter direction run.8. Oil heater: It heats the oil before the unit start, keep the good lubrication for the unit before it runs.9. 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.10. High&low pressure protection:It protects the compressor and system against extreme run condition and trouble.11. 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.12. Water flow protect:It protects the unit from run without water flow.13. 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.
