The structure of the customized semi welded plate heat exchanger is that each two corrugated plates are welded together, and then they are combined together and sealed with gaskets between each other.

For increased safety, the product range of semi welded plate heat exchanger products uses cassette plate technology instead of ordinary plates. In each plate group, the non-hazardous medium flows on the gasket side, and the hazardous medium flows in the middle of the welded plate.

The semi welded plate heat exchangers are the primary choice for applications challenging aggressive media or high pressures. Each heat exchanger can be customized to your specifications and provide durable solutions to withstand extreme conditions and minimize the risk of using chemicals or refrigerants.

In refrigeration technology, welded plate heat exchangers are indispensable refrigeration equipment. Heat exchange equipment such as condensers, evaporators, regenerators and intercoolers account for 50% of the entire refrigeration equipment in terms of weight, volume and metal consumption.

The welded plate heat exchanger is mainly used for heat exchangers, switching heat exchangers, condensers, evaporators, precoolers, subcoolers, liquefiers, oil coolers, and aftercoolers.

To improve the heat transfer coefficient of a welded plate heat exchanger, only by simultaneously increasing the surface heat transfer coefficient of the hot and cold sides of the plate, reducing the thermal resistance of the dirt layer, choosing a plate with high thermal conductivity and reducing the thickness of the plate, can the welded be effectively improved. The heat transfer coefficient of a plate heat exchanger.

Due to its own advantages, welded plate heat exchangers are more widely used in various industries. However, welded plate heat exchangers often suffer from corrosion during use.

A fully welded plate heat exchanger is a general heat exchange equipment with a certain corrugated metal plate as the heat transfer surface, and the metal plates are sealed by welding.

The semi welded plate heat exchanger uses two plates to be welded along the sealing groove by laser welding to form a plate pair, and the plate pair is sealed with a sealing gasket, which is sandwiched between the fixed compression plate and the movable compression plate in a superimposed manner. A kind of heat exchanger.
