Dry Coolers

As with the condensers, dry air coolers are finned heat exchangers. Used to reject heat from air conditioning plant chillers, water cooled variable refrigerant flow units, combined heat power installation, engines, Permatemp air conditioning equipment and a variety of other applications, they cool the water/glycol mix in a closed circuit by passing ambient air over the finned surfaces.

Dry Air Coolers are mainly used in lieu of wet systems i.e. as a replacement to cooling towers.

With power consumption now a primary considering more dry coolers are being used for free cooling, to provide all or partial cooling in lieu of refrigeration plant in low ambient conditions.
