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
