Industrial semi-welded line
Semi-welded plate heat exchangers are suitable for refrigeration, chemical processes and various kinds of industrial utility duties. The unique Alfa Laval RefTight™ sealing system guarantees a long lifetime sealing between the welded channels because the laser weld is on the outside of the ring gasket groove. The smooth surface ensures a tight uniform seal over the entire gasket ring.
Highly efficient and flexible
- Space-saving compact unit
- Low operating cost possible owing to superior energy efficiency and prolonged service intervals
- Safe and reliable sealing with no risk of cross-contamination
- Pressure and temperature fatigue resistant
Higher pressures demand a higher standard
If your heating and cooling duties demand higher pressures, it’s time for your business to demand a higher standard of technology. Discover total reliability and efficient thermal performance with the Alfa Laval range of semi-welded heat exchangers.

How it works
The sealing between the plates on the Industrial semi-welded line alternates between laser welds and gaskets. The laser welded channel allows use of fluids that are not compatible with normal gaskets and also allows for higher design pressure than fully gasketed plate-and-frame heat exchangers.
