Thermal conductivity is significantly affected by fouling, a thin insulating layer or film that accumulates on heat transfer surfaces. In fact, a fouling layer of just one thousandth of an inch (0.001") increases system power requirements by 10%. Fouling can be caused by biofilm or suspended solid particles that settle on heat exchangers. Side stream filtration with Pathex antimicrobial filter media addresses the suspended solids that contribute to fouling, as well as the bacteria that support biofilm formation. Contact AS Filtration to discuss implementing Pathex and improving heat exchanger performance at your facility.
