Double Wall Plate And Frame Heat Exchanger

The heat transfer plates have holes at the four corners forming a header that distribute the respective flows to the opposite sides of each plate when the plates align.

Double wall plate and frame heat exchanger.

Fluids normally run counter currently through the heat exchanger. Like all polaris products they are also highly efficient reliable and easy to operate and maintain. The heat transfer area of a gasketed plate heat exchanger consists of a series of corrugated plates assembled between a frame and pressure plates to retain pressure. Potential for leakage although plate and frame heat exchangers are designed to allow the plates and the gaskets between them to be firmly clamped together there is still a greater potential for leakage than with either shell and tube or spiral heat exchangers.

The fluids are confined toread more. Plate and frame heat exchangers use a combination of chevron style heat transfer plates sequenced between a frame plate and pressure. The gasket is installed in the conventional manner and the welded plate pairs are assembled in a plate pack in the same way as ordinary single plates. Double wall gasketed plate heat exchangers are ideal for use with fluids that must not be allowed to mix.

Plate frame heat exchangers also has some disadvantages in comparison with other types of heat exchangers as follows. A double seal forms pockets open to atmosphere to prevent mixing of product and service liquids in the rare event of leakage past a gasket. Plate and frame heat exchangers use a combination of chevron style heat transfer plates sequenced between a frame plate and pressure plate. The double wall plate heat exchanger works on the same principle as a conventional plate heat exchanger but differs in that the single plates between the two media are replaced by plate pairs consisting of two identical plates stacked on top of each other and welded around the portholes.

Two plates are pressed together to ensure a tight fit to minimize heat transfer losses while maintaining a leak path in case of plate failure. Gaskets are fixed between the plates to contain two separate fluids that flow alternatively to produce the highest rate of heat transfer.

Thus the units are available in the widest possible range of shapes and sizes.

Gaskets act as seals between the plates. A double wall heat exchanger can be assembled from almost any polaris heat exchanger plates. Recent developments have introduced the double wall plate. Pairs of identical plates are laser welded around the ports.
