Alfa Laval Plate Heat Exchangers
Gasketed plate heat exchangers (PHE) are a compact solution to almost all of your heat transfer needs. They provide for flexibility like no other heat exchanger in the industry today with a vast range of models with connection sizes ranging from 1" to 16". A wide variety of plate materials are available such as stainless steel 304, 316 and titanium. Exotic alloys such as monel, Hastelloy and Nickel can also be provided for corrosive applications.
Advantages of Plate Heat Exchangers:
Flow principle of Plate and Frame Heat Exchangers:
When the media enters the plate and frame heat exchanger via the connections in the frame, it's directed through alternate channels by the gasket arrangement. The warm fluid flows through every other channel and the cold fluid through the channels in between. Heat is thus transferred from the warm fluid to the colder fluid via the dividing wall, i.e. the plate material. The corrugations support the plates against differential pressure and create a turbulent flow in the channels. In turn, the turbulent flow provides high heat transfer efficiency, making the plate heat exchanger very compact compared with the traditional shell-and-tube heat exchanger.
