Marstair Marine/Bespoke Systems

Marstair Marine/Bespoke Systems

Marstair Marine/Bespoke systems are suitable for a multitude of applications, including coastal locations, extreme high and low ambients, dusty environments and onboard ships.

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
