Programmable logic control : PLC

• Able to edit operation programs through “Host” and “Device” USB ports with standard USB flash drives
• Direct connection PC without needing a serial converter.
• (Option) Connection to the controller is available over an RS485 or Ethernet network using the Mod Bus or BACnet protocol.
  

Semi-Hermetic screw compressor

• Compressors maintain the liquid flow rate to meet the working load at 50% -100% (full load).
• Effective under partial load and full load
• Designed for commercial & industrial applications.
  

Refrigerant R134a

• R134a is a refrigerant of the HFC group with no harmful effects on the ozone layer.
• No toxic
• Not combustible
• Does not corrode equipment

Evaporator

(Shell and tube heat exchanger)

• High efficiency performance , low water pressure drop Aluminium star rods fitted in copper tubing , create turbulence refrigerant flow and cause higher heat transfer efficiency.
• Removable head and proper selection of head pass avoids excessive refrigerant pressure drops.
• High column strength tube design reduces the hazard of freeze-up.
• Thick insulation to prevent condensation.
  

Condenser

(Shell and tube heat exchanger)

• Cleanable water cooled condensers are heavy duty high efficiency condensers
• Specially designed to simplify the mechanical cleaning necessary in area where poor water conditions exist.
• Working pressure
  • Shell side, 325 PSI
  • Tube side, 125 PSI
  • Test pressure 1.25 times the design working pressure
• Optional : Sea water application Copper-Nickels (90-10 / CU-NI), Tubes surrounded by steel outer tube (Shell).
  

Refrigeration part

• Hi-Low pressure gauge
  

• Solenoid valve
  Use electric power to control valve opening and closing.
  

• Sight glass
  Characterize the state and humidity of the refrigerant.
  

• Filter drier
  Filters out dirt and absorbs moisture. If the machine does not work properly or has acid build-up, the filter drier will also absorb the acid by the filter drier’s inner filling.
  

• Chilled water flow switch
  Check water flow for protect system
  

• Thermostatic expansion valve
  Controls the amount of refrigerant entering the evaporator. By installing this thermostatic expansion valve on the inlet pipe before the refrigerant enters the evaporator.
  

Electrical parts

• Magnetic & Overload contractor for fan motor and compressor
• Unit main breaker
• Digital hour meter
• Phase protection
• Pressure transducer
• Freeze stat
• Crankcase heaters
