Plate Heat Exchangers have a high heat transfer rate compared to other types of heat exchangers due to their large surface area. They are composed of a number of thin metal plates compressed together into a ‘plate pack’ by two pressure plates. Within a plate heat exchanger, the fluid paths alternate between plates allowing the two fluids to interact, but not mix, several times in a small area. Each plate is corrugated to increase the surface area and maximize heat transfer. Plate Heat Exchangers have a number of applications in the pharmaceutical, petrochemical, chemical, power, industrial dairy, and food & beverage industry.
