Double Wall Plates And Gaskets
The plate of the double wall plate heat exchanger replaces the single plate type with two welded plates. Once the plate is cracked or perforated, the fluid will flow between the two plates to the outside, which is easy to be found and taken. Doing this can avoid contamination or adverse reactions caused by the mixing of the two heat exchange media.More +

Plate And Shell Heat Exchanger Plate Pack
A bunch of circular plates made of stainless steel or other alloy material are laser welded into one body, called a heat exchanger lathed bundle, then placed in a cylinder to form a plate and shell heat exchanger. The plate and shell heat exchanger has the advantages of temperature resistance and pressure resistance with shell and tube heat exchanger, and also the advantages of high efficiency, compactness with plate heat exchanger.More +

Double wall plate heat exchanger principle
The double wall plate heat exchanger plate is welded integrally with two thin plate pieces along the corner hole of each pair of plates. When the plate leaks, for example, the perforation caused by long time working will be easily detected from outside. Thereby it stops mixing between two materials.And at the same time, they plays very important roles towards warning internal leakage. Combined with the double seal of the gasket, the possibility of mixing two materials is avoided, and it is suitable for applications with high sanitary requirements or high safety and reliability of industrial production. Since the two sheets are welded to form a sheet, the heat transfer coefficient is inevitably lowered, but the highest safety is achieved in preventing materials mixing.More +
