Cooling capacity
Cooling capacity ranging from 60ton to 320ton.
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.
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
Electric panel consist of: 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 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.
