PLATE AND FrAME - HEAT ExCHANgErS
Each plate has a gasket that produces a sealing and channel system through the entire plate
pack in which the two heat exchanging media flow in a counter-current direction.
The circul
ar portion of the gasket stops the fluid from going across the heat transfer plate and
sends it to the next open channel. The remaining portion or field gasket, directs the opposing
fluid across the heat transfer surface.
The gasket can be mechanically clipped to the plate with the glue free “U” shaped clip or glued
in place.
2.3 gaskets
The corrugated chevron pattern is alternated from plate to plate. This gives the plates contact
points for pressure resistance and also forms a liquid stream that is subject to extensive tur-
bulence resulting in a high heat transfer coefficient, as well as reducing the risk of deposits on
the heat transfer surface.
The gasket is double around the ports to prevent intermixing of the two fluids. In the event of
gasket failure, any leakage is vented external to the equipment.
