In comparison to all-welded heat exchangers, our semi-welded plate heat exchangers have high thermal efficiency and low running cost. Instead of ordinary plates, the semi-welded product range employs cassette technology for greater safety. Two corrugated plates are stacked on top of each other and laser fused together as a cassette along the sealing groove created for the semi-welded PHE gasket.
For aggressive media, we specially offer a semi-welded plate for PHE. To make the plate cassette, two pieces of PHE stainless steel plates are welded back to back using a laser along the sealing groove for the gasket. The ordinary media side of each cassette is gasketed, while the aggressive media side is welded. A unique, damage-resistant ring gasket is mounted on the welded side. Only two of the four-ring gaskets at the inlet and outlet are contacted as the refrigerant flows from one cassette to the next. Our semi-welded plate heat exchangers have a long product lifetime and ensure safe operation with less danger of leakage thanks to a significant reduction in exposed gasket area.

I found about their semi-welded plate heat exchanger plates that employ advanced laser welding technology, which offers low welding deformation, low residual stress, and comparably of good quality. Also their technicians help whenever needed. One of the best plate heat exchanger manufacturers in Delhi.
Thermal and mechanical tests have confirmed the design of the semi-welded plate heat exchanger. Great product!
