Pfannenberg Water/Water Heat Exchangers

Shop by Brand

 

When source water from cooling towers, lakes and rivers, well water, and potable city water is too cold or contaminated to be directly circulated to certain devices or vessels, a water-to-water heat exchanger can be used to overcome such obstacles and deliver clean coolant at optimum temperature for critical needs.

Pfannenberg Series PWW water-to-water heat exchangers are designed with durable components to ensure the effectiveness and longevity of the critical cooling process at hand. Each unit offers two isolated water circuits – one on the supply side, and one on the process side. The process side includes a coolant reservoir and a circulating pump. The supply side includes an electronically actuated ball valve for modulating source water flow rate in order to maintain the desired process and/or equipment temperature. Options include supply side filters for dirty water and high pressure pumps for long process side pipe runs.
