They are almost alike to Gasketed plates with the only difference, that the plates are welded together instead of being sealed. These heat transfer plates are extensively used in distinct plumbing applications. Fluids with high temperature and from corroded material can be easily transferred through these plates. Some functionalities serve by such units are caustic soda transfer, oil cooling, heating with expensive or hazardous liquids and heat transfer through liquids.
Semi-Welded Plates
Two welded plates are gasketed together, which makes this heat transfer plates a perfect combination of other two types. So, a great combination of two units is obtained which can be used for transferring intense liquids and semi-liquids. They serve functionalities similar to welded plates.
Brazed Plates
These are plates made up with stainless steel which are used in almost all refrigeration and industrial applications. Since, they are composed of qualitative stainless steel, so they are free from corrosion and chlorination. Their effectual functionalism and compact size make them suitable to be used in heat pumps, hydraulic or engine cooling systems, swimming pool heating system, refrigerants and in condensers. They are also utilized in district and zonal cooling systems.
Constructers can choose one among these different types so as to meet their need in an effective manner.
