What is a Semi-welded Plate Heat Exchanger?

A semi-welded plate heat exchanger is a type of heat exchanger that combines the advantages of both gasket and fully welded plate heat exchangers. It features a combination of plates that are sealed with gaskets and plates that are welded together.
The semi-welded design offers several benefits in terms of performance and durability. The welded plates provide a leak-proof solution, ensuring that there is no cross-contamination between the two fluids being exchanged. This makes the semi-welded plate heat exchanger suitable for applications involving aggressive or corrosive fluids.
The gasketed plates, on the other hand, allow for easy maintenance and cleaning. They can be easily removed or replaced, making it convenient to access the plates for inspection or maintenance purposes. This flexibility also allows for easy adaptation or modification of the heat exchanger to meet changing process requirements.

Advantage of Semi-welded Plate Heat Exchanger

1. Space-saving compact design

2. Flexibility to Adjust Heat Transfer Area for Varied Capacities and Refrigerants

3. High-pressure resistance is about 2 to 3 times higher than gasket plate heat exchangers

4. Especially well-suited to ammonia-based application
