Semi-Welded exchangers are two plates laser welded together to form a cassette.
The advantage of this construction is that, one side of the cassette is a sealed welded channel, whilst the other is a traditional gasketted plate channel making assembly and cleaning of this site easier.
- Laser welded plates
- Safe operation without leaking
- High working pressure
