Below is a list of Recirculating Chillers manufacturers from Waltham, Massachusetts. Recirculating chillers are refrigerated liquid cooling systems that recycle the same refrigerant liquid within a closed loop. They provide precise, continuous duty temperature control by constantly recirculating a coolant through the temperature control unit, reservoir and refrigeration unit by a circulation pump, which is all housed in a casing. These units are compact, self-contained and usually portable due to caster mounts which allow easy transportation over hard, flat flooring.
