Products Construction

A heat exchanger consists of a number of heat transfer plates which are held in place between a fixed plate and a loose pressure plate to form a complete unit. Each heat transfer plate has a gasket arrangement which provides two separate channel systems.

The arrangement of the gaskets (field and ring gaskets) results in through flow in single channels so that the primary and secondary media are in counter-current flow. [View illustration]

The plates are corrugated which creates turbulence in the fluids as they move through the unit. This turbulence, in association with the ratio of the volume of the media to the size of the heat exchanger, gives an effective heat transfer coefficient. We offer a full range of sizes, plate and gasket materials suitable to application needs.

A similar principle is employed in the Brazed Plate Heat Exchanger construction. Instead of the elastomer gasket, special brazing techniques are used to give the same results. Again, we offer a full range of material construction suitable to the application needs.

We also offer a new fusion bonded stainless steel plate heat exchanger for situations where elastomer gaskets or copper or nickel brazing is not suitable.
