Heaters and cooler
Semi-Welded heatexchangers 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.
Advantages:
- Laser welded plates
- Safe operation without leaking
- High working pressure
- Can be used for evaporators and condensers
- Suitable for NH3
- Minor gasket area
- Small liquid volume
