25 kW – 80,000 Btu/h
Our PWW 25000 Water/Water Heat Exchangers is based on the passive cooling principle. This product is ideal for utilizing a contaminated water source, such as river water or low quality tower water without compromising the critical liquid cooled components. Two separate circuits allow the heat to be transferred from the “dirty” side to the clean side protecting electronic components such as liquid cool drives. Design: Rugged construction – (G90) galvanized steel with polyester powder coat finish
