What are Heat Exchanger Plates Used For?
Sometimes referred to as a plate heat exchanger, plates used to facilitate the indirect transfer of heat between fluids have been around for about a century. The first ones were invented in 1923 by Dr. Richard Seligman. Heat exchanger plates were introduced to pasteurize milk at high temperatures for shorter periods, which has since become the standard method for pasteurizing milk. Unlike other heat exchangers, plates expose fluids to considerably more surface area, which speeds up temperature changes. Now used globally for multiple other applications that include pasteurization, heat exchanger plates have since developed to the point that more recent models are made with thin metal plates designed via computers, with certain types even utilizing laser technology.
