Air-cooled screw chiller(heat pump)

• Compressor Type: Screw
• Refrigerant: R-407C, R-134A
• Capacity Range (Tons): 80 – 360
• Capacity Range (kW): 290 – 1,250

Key Features:

• SEMI-HERMETIC COMPRESSOR: Semi-hermetic screw compressor for the whole range. Each compressor is equipped with a crankcase heater and a built-in electronic protection. The compressor steps or stepless energy control, adapt to the changes of different part load.
• EVAPORATOR: Evaporator built with high efficiency horizontal type shell and tube heat exchanger, with stable, low resistance and efficient heat exchange.
• CONDENSER: Condenser b u i l t with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins. Low noise, energy saving axial fan, guarantees long service life of the unit. Micro-channel type condensor is available.
• REFRIGERANT CIRCUIT: Circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, electronic expansion valve, high and low pressure switch, safety valve.
• ELECTRIC PANEL: Compressor contactor, fan motor contactor, compressor protection breaker, fan protection breaker, phase sequence relay and microprocessor with function display (display only for master/packaged unit) Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.
• CONTROL SYSTEM: Each unit is equipped with a known brand PLC control system. This system is to provide precise and stable control in long-term running. Meanwhile, it offers perfect communication function, which is convenient to realize interface with building control system.
