Dry coolers (also known as radiators, finned fan coolers) work by convection and conduction to dissipate heat from the process fluid into the airflow created by the fan mounted on it. With proper selection of tube materials, we can use dry coolers to efficiently cool or condense process water, chemicals or any heat transfer fluid, even if it is corrosive or contaminated with particles. Dry coolers are closed loop systems that eliminate any type of moisture loss, thereby eliminating the constant need for make-up water. As a closed loop, water treatment costs are also negligible compared to traditional evaporative cooling towers.

Two types of dry coolers "V" and "Horizontal" are available depending on the application or requirement. Depending on the application, the fans can be installed according to the induced draft or forced draft type. The fans are direct drive but can also be optionally fitted with a gearbox or belt drive. Tubes carrying process fluids are constructed of copper, carbon steel, or stainless steel with aluminum fins to maximize heat transfer. We offer two variants of fin configurations such as continuous fin and high fin tube bundles for optimal selection depending on the working fluid temperature. The side panels are epoxy coated for corrosion resistance and a great look.

Advantages of the chiller: Efficient finned tube heat transfer; Zero use of water resulting; Zero water waste: No evaporation due to closed loop operation; No water treatment plant: as it does not require a continuous supply of make-up water; Negligible maintenance costs: No need for water treatment, refilling and replacement of filling
