Heat Exchanger - Without fan

ATS tube-to-fin, liquid-to-air heat exchangers are made with the industry’s highest density fins to maximize heat transfer from liquid to air, allowing the liquid to be cooled to lower temperatures than other heat exchangers on the market. The heat exchanger fins and tubes are made of copper to be suitable for a variety of fluids, including water, dielectric fluids, and custom designed heat transfer fluids.

Each of the eight heat exchanger sizes is available with or without a fan. ATS heat exchangers can be used in laser cooling, medical equipment and imaging devices, compressor cooling, semiconductor processing, HVAC, food and beverage processing, and other liquid cooling applications.

Complete Your Liquid Loop with ATS

ATS has the products needed to design a complete liquid cooling loop : iCDMs (Industrial Cooling Distribution Modules), Tubed and High Performance Cold Plates to transfer and remove the heat from the source; Heat Exchangers to transfer heat from the liquid to the air with or without a fan; Chillers to circulate and condition the fluid in the system, Compact Refrigeration Modules for very high capacity cooling. In addition , ATS offers Flow Meters to measure the volumetric flow rate of the fluid in the system and Leak Detectors to notify users of any leaks in the system.
