PolyScience Non-Refrigerated Recirculating Coolers

Category Chillers
Manufacturer PolyScience
Country of manufacture the United States of America

Quiet, energy-efficient heat removal. Available in both Liquid-to-Air 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-Air Cooler Specifications

  • Working Temperature Range: Ambient +5° to 70°C 
  • Maximum Fluid Temperature: 70°C 
  • Cooling Capacity: 4000 watts based on 24°C Δ T (water)
  • An economical solution for applications where cooling fluid temperature is higher than ambient and temperature control is not required
  • Quiet liquid-to-air cooling
  • Positive displacement or turbine pump
  • Built-in low liquid level indicator

    Please note: PolyScience chillers are manufactured at the time the order is placed and have a 2-3 week lead time.
