Closed Loop Liquid Coolers

Pneumatech's closed loop system avoids water loss and contaminant buildup as is possible with open tower water cooling systems.

Low cost cooling system - low power consumption
Energy saving - dissipated heat can be recovered for space heating
Closed loop system eliminates water consumption (of cooling tower system), reduces sewer charges - no loss of industrial fluids
Uses ambient air - can be installed to provide air make-up
Can be used with ethylene glycol for winter operation
Approach temperatures of 5 °F and above
