Production Introduction: These plates provide maximum protection against the mixing of media used in the heat exchange process.Two simultaneously embossed plates are laser-welded at the port holes.If there is a leak,fluids can escape at the edges of the plate pair.All models can provide double-wall plates.
When the hot and cold medium of plate heat exchanger mixing will produce harmful reaction, we need to use double plate wall safety plate heat exchanger. Double plate wall safety plate heat exchanger is widely used in food, medicine, municipal water supply, metallurgy, electric power and chemical industry.
Principle: Double plate wall safety plate heat exchanger works in the same principle as ordinary plate heat exchanger. The difference is that each heat transfer unit consists of two plates welded together, and the two plates are specially pressed so that they fit together completely to reduce thermal resistance.The four corner holes are welded by laser to form a heat transfer unit, which is equivalent to a sheet of ordinary removable heat exchanger. Can be used with ordinary plate seal. When the plate crack or perforation, any side of the fluid leakage, will flow out of the gap between the plate group; Either side of the fluid leakage part are positive pressure, will never flow to the other side of the medium, to ensure the absolute safety of the other side of the medium.
