Our customers - Become one too!
Plate heat exchangers are used wherever heat needs to be transferred efficiently from one medium to another. Thanks to their compact design, high heat transfer efficiency and versatility, they are now an integral part of technical processes and plant in numerous industries.
The process can be divided into four simple steps. First, the hot and cold fluids enter the plate heat exchanger through separate connections. Second, both fluids flow through alternating channels between the heat transfer plates, creating a large surface area for efficient heat exchange. Third, heat is transferred through the thin metal plates from the hot fluid to the cold fluid, while both media remain completely separated and never mix. Finally, the temperature of both fluids changes as they pass through the unit: the hot fluid cools down and the cold fluid heats up before leaving the heat exchanger.
