Semi-welded, All-welded


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
  • Can be used for evaporators and condensers
  • Suitable for NH3
  • Minor gasket area
  • Small liquid volume



Offer olwer purchase cost and smaller foot print whilst maintaining high heat transfer efficiency. The small plate gaps in the all-welded heat exchangers allow them to operate with very close temperature approaches compared to traditional shell and tube heat exchangers. The no gasket solution in the all-welded heat exchangers makes them suitable for many difficult applications.
