Construction
Corrosion resistant thin plates of stainless steel, titanium etc., are pressformed into heat transfer plates. A seal gasket is attached onto each plate. These plates are suspended from guide bar and bolted together between a fixed frame and a movable frame. Constant spacing between the plates allow the fluid to flow through. The inlet and outlet connections are fixed onto eitherthefixed frame or the movable frame.

Heat transfer plates
Each heat transfer plate is corrugated to various patterns to increase its strength and heat transfer area. Furthermore, the corrugation creates high turbulence and thereby achieve high heat transfer coefficient. The plate is provided with passage hole on each corner. Each plate is tight-sealed with a gasket fitted in its peripheral groove.

Flow channel
The plates are divided into A-plate and B-plate, and a passage is formed between these plates. The high temperature fluid flows alternately and in the opposite direction of the other fluid. Thus high heat transfer of the other is achieved through these plates.

A-plate when reversed would become B-plate. As such only one type of plate can be used as A-plate and B-plate for most models.
