BESPOKE OPTIONS

  • A wide range of internal unit options
  • A wide range of case and heat exchanger material options
  • 3 phase no neutral electrical option
  • High IP rating fans and electrical enclosures
  • BMS Alarm
  • Wide fin pitch heat exchanger
  • Hot gas bypass capacity regulation valve
  • External ambients up to 55 deg C
ELECTRICAL OPTIONS
  • Supply Options - the 3 phase no neutral electrical option is available for applications with a local 3 phase generator. The small single phase requirement (Maximum 5A @ 240V) for the fans and controls are generated by transforming 400V between phases down to 230V using a specially designed transformer within the condensing unit.
    - 1 Phase
    - 3 Phase with Neutral
    - 3 Phase no Neutral
    - 50 or 60Hz
  • High IP rating fans and electrical enclosures are available for higher fluid and dust ingress protection
    - Moisture & dust ingress protection IP44 or IP65
    - Fan Motor IP44 or IP65
  • For integration into modern building management systems
    - BMS Run
    - BMS Alarm
  • A convenient option for saving time on site or where space is not available for external isolation
    - Fitted Isolator 
ABNORMAL CONDITIONS
  • External Ambient Systems, condensing units and evaporators available for use with R134A for exceptionally high external ambient conditions
    - 40°C Maximum
    - 55°C Maximum (R134A Only)
  • Coil Guards - For heat exchanger protection against direct impacts
  • Hot Gas Bypass Capacity Regulation Valve - for a more precise capacity control especially when cooling at exceptionally low external ambients
  • Compressor Crankcase Heater - for compressor protection at exceptionally low ambients
  • Wide Fin Pitch to Reduce Blocking - for environments where the heat exchanger is expected to block up rapidly, such as cement works
