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.
