Water Cooled | DX | R407C

Ultima™ Water Cooled 75kW - 450kW

  • Scroll
  • Water Cooled
  • HFC R407C

The Ultima™ Water Cooled (UWC) is some of the most advanced chillers ever produced by Airedale, thanks to our on-going programme of extensive development and technical innovation. The range has been designed specifically for use in plant room applications with energy efficiency, low sound levels, cost effectiveness and the environment in mind.

Low Sound Levels

Airedale International Air Conditioning recognises that noise pollution is a very important issue in today’s populated environments, with many urban areas having already introduced strict noise pollution regulations. The UWC has been developed with low sound levels as a key factor in design.


  • Electronic expansion valves offer significant energy savings
  • Evaporator pad heater provides frost protection and prevents refrigerant migration when compressors are not in operation
  • Dual independent refrigeration circuits
  • High efficiency integrated dual circuit brazed plate evaporator
  • Multiple scroll compressors provide staged capacity control enabling system water volumes to be reduced and part load efficiencies to be increased
  • Designed and optimised for R407C refrigerant
  • Liquid and discharge line shut off valves
  • High efficiency brazed plate condensers
  • Dedicated compressor enclosure provides good maintenance access while helping to keep noise levels to a minimum (DQ / DSQ models only)
  • Integral pressure relief valve assembly with indicator gauge
  • Output to external head pressure controller (FSC or modulating 3-way valve)
  • Victaulic connections on evaporator & condenser provide low noise, cost savings and a significant reduction in installation & maintenance time

Features

  • ETL listed: Energy Technology List www.eca.gov.uk
  • 75 – 450kW nominal cooling capacities
  • 45 models
  • Standard, Quiet and Extra Quiet variants
  • Dual independent refrigeration circuits
  • Compact unit footprint
  • High efficiency plate heat exchangers

Options

  • Anti vibration mounts (pad or spring type) for noise sensitive installations
  • Electronic soft start significantly reduces the compressor starting current
  • Evaporator and condenser water filter
  • Leak detection kit (DQ / DSQ models only) provides an indication of any refrigerant leak within the chiller
  • Sequence controller for multiple chiller applications
  • Dual pressure relief valve allows inspection of pressure relief assembly without the requirement to reclaim the system refrigerant
  • Remote set-point adjust
  • Evaporator & condenser flow switch (supplied loose) to protect the chiller from damage caused by reduced water flow
  • Matching dry coolers and air cooled condensers are available for each model size
