Semi Welded Plate Heat Exchangers are as flexible as gasketed heat exchangers while enhancing the application range for PHEs for use with aggressive liquids and gases, such as ammonia and aggressive process chemicals where suitable elastomers are not available to act as a sealant between the plates. In the case of ammonia refrigeration, the reduced hold-up volume results in significant additional savings.

Laser welding technology has also helped us in developing double wall plates. The double plates are constructed by laser welding 2 identical plates around the ports. These double wall plates offer maximum safety against intermixing of the two fluids in the plate type heat exchanger.
