Semi-welded heat exchangers are the perfect choice for a wide range of refrigeration systems. They offer benefits such as excellent heat transfer efficiency, easy capacity expansion and high resistance to fatigue.
Ammonia is a common refrigerant and is used in many applications. In some cases, operators notice a weak smell when they are very close to a semi-welded heat exchanger and worry that gaskets may be leaking. Alfa Laval have demonstrated that the smell is due to a natural process called permeation and not a faulty gasket. They have also demonstrated that the amount of ammonia released to the surroundings is very low and that it does not cause any harm.
Alfa Laval have produced a White Paper that addresses the use of ammonia as a refrigerant in semi-welded heat exchangers and provides more information.
