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 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.
