Delta T system cools with ambient air

June 21, 2023
The Free Cooling System offers high-performance cooling without requiring traditional refrigeration.

Free Cooling System This Delta T Systems cooling system uses ambient air to cool process fluid used in a wide variety of industrial processes, including injection molding. In contrast to a chiller unit, which requires a refrigeration system to cool the process fluid, the Free Cooling System pumps hot process fluid through an outdoor coil and a fan blows ambient air across it to cool the fluid, which is then pumped back into the process.  

What’s new? The Free Cooling System. 

Benefits Cost-effective, energy-saving cooling. The Free Cooling System offers high-performance cooling without requiring traditional refrigeration. It has a small footprint, with the ability to fit through a standard 36-inch doorway, and microchannel heat exchangers that offer more surface area in a smaller package. It has a 4-inch touch screen, logs temperature and pressure data continually for historical reference, and can capture data at the time of an alarm event.
