TurboChill™ & TurboChill™ FreeCool

TurboChill™ & TurboChill™ FreeCool 200kW – 1830kW

Winner of ‘Energy Saving Product of the Year’ at the CIBSE Building Performance Awards 2015, the TurboChill™ is the first BSI approved range of high performance turbo chillers using the low GWP refrigerant R1234ze available from a British manufacturer.

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 hydro-fluoro olefin (HFO) refrigerant R1234ze makes the TurboChill™ a highly sustainable option, which automatically receives two 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.

An air-cooled, single/dual circuit R134a/R1234ze high capacity chiller unit designed around revolutionary centrifugal Turbocor compressors integrated with cutting edge components. Brilliantly engineered, using Airedale’s vast expertise in cooling technology, the TurboChill™ minimises environmental impact by lifting efficiency to new heights and pushing down sound levels.

The intelligent, self-optimising compressors present near silent, oil-free operation and ultra-efficient, variable speed control. This allows TurboChill™ 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.

Offering exceptional ESEER value, the TurboChill™ offers increased flexibility and choice with more than 230 models available to choose from. 76 of these models have been specifically developed for use with the low Global Warming Potential (GWP) refrigerant R1234ze, whilst 110 TurboChill™ models from the range combine the latest compressor technology with the power-saving benefits of free-cooling.

TurboChill™ matches load requirements exactly and enables selection of the optimum model, in terms of efficiency, sound level, footprint and price, for each individual application.

TurboChill™ FreeCool – ultimate efficiency

For the ultimate in energy efficient chiller solutions, the new TurboChill™ FreeCool 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.

Energy optimisation – ESEER 6.23

The TurboChill™ FreeCool achieves 1-100% free-cooling, year round. During any mechanical cooling, the excellent part load efficiencies of the TurboChill™ FreeCool ensure an ESEER* of up to 6.23.

*ESEER (European Seasonal Energy Efficiency Ratio) is based on the part load efficiency of TurboChill over the course of a year and is a better indicator of real energy draw and running costs.

Units within this range are Ecodesign compliant for both process (SEPR) and comfort cooling (SSCEE) applications. Please refer to the technical manual, website, or your Airedale account manager for full details
