Double Wall Plate Heat Exchanger

The perfect choice to prevent fluids from intermixing that combines the high-efficiency heat transfer benefits of conventional plates with a design that eliminates the risk of mixing.

The double-wall design means that any leakage of either of the two fluids passing through the heat exchanger shows up on the outside of the heat exchanger, which can thus be taken out of operation for service.

Alfa Laval and SWEP double-wall plate heat exchangers are therefore ideal for use with fluids that must not be allowed to mix because of the environmental effects, deterioration of process fluids or because it would be hazardous.

Advantages of double-wall plate heat exchangers

Double-wall plate heat exchangers achieve heat transfer coefficients that are normally two to three times higher than in shell-and-tube heat exchangers. This means that the heat transfer area required is significantly smaller, which in turn makes a crucial difference in terms of initial investment, especially when stainless steel or more exotic materials are needed. In addition, the low weight and compact design mean that installation costs are much lower.
