Suited for applications where the fluids have relatively low viscosity with no particles, the plate heat exchangers also can be used where the product outlet temperature is close to the service inlet temperature. They consist of thin, corrugated plates packed inside a frame. The product to be cooled or heated flows in alternate channels, and service fluid passes in between product channels. The compactly designed plate heat exchangers range consists of a number of herringbone patterned, pressed heat transfer plates. All plate heat exchangers are designed to give the correct thermal length for the heat transfer required. Two types of thermal length plates, high and low theta, are available so that unit sizes can be optimized across a range of processes. The company’s plate heat exchangers also have a flexible design so that multi-section units — consisting of two or more plate packs separated by intermediate pressure plates or C-plates — are possible.
