Industrial semi-welded heat-exchangers

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.

• Space-saving compact unit
