Chillers and Coolers

PolyScience Chillers and Coolers have proven, over several decades and hundreds of thousands of installations, that they are the most reliable in the industry — and an exceptionally smart choice for end-user and OEM applications ranging from lasers and analytical equipment to reactors and manufacturing equipment.

PolyScience Recirculating Coolers

Quiet, energy-efficient heat removal

Available in both Liquid-to-Air and Liquid-to-Liquid models, PolyScience Recirculating Coolers deliver extremely quiet and energy-efficient heat removal. They provide significant cooling for set-points above ambient, without the energy consumption of refrigerated chillers.

Liquid-to-Air Cooling

Uses ambient air to cool your application. Heated process fluid is pumped through the unit's fan-cooled heat exchanger and returned to the process.

Liquid-to-Liquid Cooling

Uses your facility's water, pumped through the unit, to remove heat from your application without risk of contamination. Heat removal capacity is dependent on the facility water temperature.
