PolyScience Non-Refrigerated Recirculating Coolers
Overview 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 CoolingUses 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.
