Plate materials and the gasket materials of Plate heat exchanger mainly depend on the corrosive properties and temperatures of the cold exchange medium and the heat exchange medium. Plate and shell heat exchangers can be used as evaporators, condensers, condensing evaporators, superheated steam coolers, oil coolers, etc., bringing many benefits to advanced refrigeration applications. All - welded plate - shell heat exchanger is efficient, durable and versatile. It is compact and requires very little refrigerant charge. It works with all refrigerants, especially the natural refrigerants ammonia and carbon dioxide The plate heat exchanger's plate materials and corresponding applicable places are given in Table 1 and its gasket materials and corresponding applicable places in Table 2 for your reference.

Table 2 Gasket Materials
Introduction to Sealing Gasket
The sealing gasket is inserted and fixed to the slot in a heat-exchanging sheet, featuring easy insertion and replacement of sealing gasket, which can substantially reduce stoppage time. The sealing function is separated from fixing function. Even if some "clamps" with fixing function fail, the gasket can still have a sealing function in the slot.
