Caractéristiques des échangeurs de chaleur à refroidissement par air
Les échangeurs de chaleur à refroidissement par air Alfa Laval présentent une série de caractéristiques de conception uniques qui les distinguent sur le marché.
Slitted fin design maximizes heat transfer
Alfa Laval’s HyperFin slitted tube fins increase heat transfer compared to standard API 661 type fins, resulting in reduced size and cost of the cooling system.
The slits on the aluminium fins interrupt the air flowing over the fin surfaces. This prevents the forming of a stagnant layer of air on the fin surfaces, and thereby increases heat transfer. The impact on the pressure drop and required fan horsepower is minimal, keeping operating costs low.

Effectively prevents leaks from the plugs in the header box
Leaks from the plugs in the header box of air-cooled heat exchangers operating under high pressure is a well-known problem for plant owners around the world. Alfa Laval’s unique SealTight system effectively puts an end to this problem.
The SealTight system comprises specially designed plugs, plug gaskets, threading and seats, and offers a highly effective and reliable sealing. SealTight is available in a wide range of materials for different applications.
With SealTight you get a safer and more environmentally friendly plant. The avoided leaks reduce maintenance work, and when your heat exchangers need service, the plugs are easy to remove and replace without risk of over torquing.
