OptiChill Free-cool: Airedale’s new R134A free-cooling chiller 750kW – 1300kW launched

British air conditioning manufacturer Airedale International Air Conditioning has launched a new super efficient, low energy R134a air cooled screw chiller which has the potential to offer more than 95% free cooling over a year (cumulative hours London, UK).

The free-cooling potential of the unit provides a free-cooling EER of up to 75* and can also save more than 50% of the energy consumed by a conventional chiller; driving down operational costs. During any mechanical cooling, excellent part load efficiencies ensure an ESEER (European Seasonal Energy Efficiency Ratio) of up to 3.44.

Airedale’s OptiChill free-cooling chiller has an extremely large capacity and meets diverse cooling loads with a flexible, low sound solution.

*Free-cooling EER at 15ºC return water; 20% ethylene glycol; 3ºC ambient temperature
