Plate Heat Exchangers are an indirect method of heat transfer consisting of metal plates bound and heated to transfer thermal energy across a much larger surface area than other types of heat exchangers. SPX FLOW heat transfer engineers develop plate heat exchanges to fit the customer’s needs. Custom plate heat exchangers often vary in the number of plates bound in the heat transfer system. Plate heat exchangers may also differ in the design of the thermal plates themselves. Different configurations etched into the plate influence the thermal-hydraulic performance of the heat exchanger. For example, the corrugations or etchings on each plate may promote more turbulent product flow, decreasing fouling through higher product movement.
