Braze Plate Heat Exchangers are made by pressing a series of thin corrugated stainless steel together and brazed with copper or nickel. The soldering material is then melted in a vacuum furnace to form a seal between each of the plates. This brazing process seals the plates together making extremely durable and allows for Brazed Plate Heat Exchangers to perform under high working pressure and temperatures. The spaces in between the plates become flow channels with one fluid flowing in odd number channels and the other in the even number channels. Heat exchange occurs through the designed plates over a large surface area making Braze Heat Exchnagers very efficient. Nearly all of the material is used for heat transfer making it also very compact and cost-effective
