Leading 5TR Air-Cooled Water Chiller Manufactures in Chennai and Kerala. Air cooled chillers absorb heat from process water, and the heat is then transferred to the air around the chiller unit. This type of chiller system is generally used in applications where the additional heat it discharges is not a factor. In fact, it's often practical to use the excess heat to warm a plant during the winter, thus providing additional cost savings Air cooled chillers require less maintenance than water-cooled units.Air cooled chillers do not require a cooling tower or a condenser water pump.Consume approximately 10% more power than a water-cooled unit due to wet surfaces transferring heat better than dry surfaces.
