Ultima R32

Ultima R32

The Ultima R32 is a high efficiency, compact, air-cooled single/dual circuit chiller. Optimised for R32 refrigerant and now operational with an increased supply water temperature of up to 18°C, the Ultima R32 has been engineered to increase efficiency and deliver improved performance.

Developed with low sound levels as a key factor in its design, the Ultima R32 is perfectly suited to a variety of environments including data centres, retail, manufacturing and leisure. It is available with an extensive range of hydronic options seamlessly designed within the unit to reduce installation time, foot print and operating costs

Energy Efficiency

  • 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
  • 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
