Ultima™ Compact & Ultima™ Compact FreeCool

Ultima™ Compact & Ultima™ Compact FreeCool

The Ultima Compact Chilller is a high efficiency, compact, air-cooled single/dual circuit chiller, which offers exceptional ESEER and EER ratings.

ESEER of up to 4.42
Up to 62% free cooling
Developed with low sound levels as a key factor in its design
Extensive range of pump options and buffer tanks to reduce operation costs


Units within this range are non-Ecodesign compliant but can be used in process applications that are above >12°C supply water temperature, as these fall outside the Ecodesign parameters. Please refer to your Airedale account manager for full details

The Ultima Compact range has been engineered using the very best chiller technology and components to increase efficiency and deliver improved performance, incorporating next generation DSH scroll compressors.

ESEER of up to 4.42

Developed with low sound levels as a key factor in its design, the Ultima Compact Chilller is ideally applicable to a variety of environments including data centres, retail, manufacturing and leisure.

Available with an extensive range of pump options and buffer tanks to reduce installation time, foot print and operating costs.

Energy Efficiency

  • Up to 62% free cooling of UCFC DX performance
  • Electronic expansion valves offer an energy saving whenever the outdoor ambient is below design*
  • Modulating head pressure control on all models ensures energy efficient operation of the condenser fans whilst protecting the system during low ambient operation
  • Single (Models UCC 30-80 only) and dual independent refrigeration circuits
  • Condenser fan discharge plenum reduces noise
  • High efficiency, dual circuit brazed plate evaporator
  • Unique design enhanced condenser coils ensure an even air distribution
  • Multiple scroll compressors provide staged capacity control enabling system water volumes to be reduced and part load efficiencies to be optimised
  • Designed and optimised for operation with R407C refrigerant
