Free Coolers
Saves energy and makes chilled water systems more environmentally friendly
Free Cooling for water cooling applications is achievable for most of the year for many applications using Dry Air Coolers. The Dry Air Cooler is arranged in series with the refrigeration water chiller – as the return water is pre cooled by the Dry Air Cooler the load on chiller and power consumption is reduced. Energy savings are immediate when the ambient is 1° C below the return water temperature to the chiller and increase as the ambient reduces to a point where 100 % FREE COOLING is achieved by the Dry Air Cooler.
Fast pay back – year round energy saving.
