Description
PolyScience 3370P9A11B – Liquid-to-Air Recirculating Cooler with Positive Displacement Pump, 120V, 60Hz

- Quiet liquid-to-air cooling
- Positive displacement or turbine pump
- Built-in low liquid level indicator
This Liquid-to-Air Recirculator continuously pumps near-ambient temperature water from a reservoir to an external heat source, through a cooling radiator, and then returns cooled water to the reservoir. By blowing ambient air over the radiator, water flowing inside is cooled and the heat is exhausted into the atmosphere.
