  • Micro channel coils
  • Free Cool
  • EC Fan
  • Centrifugal Compressor
  • HFO R1234ze

The TurboChill™ spray evaporator range has been designed with the future of refrigerants in mind. The range uses spray flooded evaporator technology, which allows the system charge to reduce by over 50% compared to a standard flooded heat exchanger. Savings of up to 70% refrigerant charge can be made in the evaporator alone. The TurboChill™ delivers an industry-leading energy efficient cooling solution with capacity to deliver up to twice as much free-cooling as equivalent thermosiphon products. The addition of low GWP refrigerants R1234ze and R513A makes the TurboChill™ a highly sustainable option, which automatically receives three BREEAM points in recognition of its low global warming impact.

R1234ze readily breaks down in the atmosphere within a very short lifetime (16.4 days) and is rated by the International Panel for Climate Change (IPCC) with a 100-year GWP lower than 1, which performs better than CO2.

All units incorporate the latest Centrifugal TurboCor compressor technology including the low capacity TG230 compressor which uses R1234ze. These intelligent, self-optimising compressors enable 30 – 100% variable speed control with respect to maximum capacity and working conditions for tighter setpoint management and unbeatable efficiencies at part load.

The intelligent, self-optimising compressors present near silent, oil-free operation and ultra-efficient, variable speed control. This allows the TurboChill™ Spray Evaporator to match load requirements exactly and enables selection of the optimum model, in terms of efficiency, sound level, footprint and price, for each individual application.

The TurboChill™ Spray Evaporator range offers increased flexibility and choice with more than 166 models available to choose from. 52 of these models have been specifically developed for use with the low Global Warming Potential (GWP) refrigerant R1234ze, whilst 78 TurboChill™ models from the range combine the latest compressor technology with the power-saving benefits of free-cooling.

TurboChill™ FreeCool Spray Evaporator – ultimate efficiency

For the ultimate in energy efficient chiller solutions, the new TurboChill™ FreeCool Spray Evaporator combines the unparalleled efficiency of centrifugal Turbocor compressor technology, with the power saving benefits of free-cooling. The oil-free operation of the revolutionary Turbocor compressor allows infinitely variable speed operation giving exact capacity match and using substantially less power at part load. Units within this range are Ecodesign Tier 2 compliant for both process (SEPR) and comfort cooling (SSCEE) applications.

  • Centrifugal compressor - 25-100% variable speed control for tighter setpoint management and substantial energy savings at part load
  • Spray evaporator - allows the system charge to reduce by over 50% compared to a standard flooded heat exchanger. Savings of up to 70% refrigerant charge can be made in the evaporator alone
  • Microchannel heat exchanger - high surface area provides increased heat transfer and lower airside drop giving lower fan powers; the slim, light profile reduces weight / space claim
  • Modular V-frame - vastly improves heat exchange, resulting in better performance and control particularly at part load; also facilitates easier maintenance
  • In-built low current start (2A)
  • Oil-free operation enhances heat exchanger efficiency
  • Up to two Turbocor compressors across a single circuit for reduced energy consumption at part load
  • Intelligent compressor management by network-capable AireTronix controls
  • Large surface area condenser coils with latest fan technology
  • EC fans and interactive head pressure setpoint management give increased performance for reduced power input
  • Chiller Sequence Manager (option)
  • Automatic rescheduling of chilled water setpoint
  • Economiser circuit provides increased cooling and enhances EER in full and part load operation

      Options

      • Leak detection system for F Gas compliance (standard for R1234ze models)
      • Automatic refrigerant pump down in the event of a refrigerant leak, which together with leak detection, qualifies the TurboChill™ for one additional BREEAM point (standard for R1234ze models)
      • Corrosion-resistant condenser coils for corrosive atmospheres (option for FC models, standard otherwise)
      • Variable supply water temperature control to save power and raise the free-cooling threshold
      • Energy Manager is a compact, space saving analyser which enables monitoring of the TurboChill’s energy consumption locally and remotely via BMS connections
