How it works

Alfa Laval finned coil air heat exchangers have been designed to achieve an optimized exchange of thermal energy between air and a refrigerant or fluid. The ‘heart’ of our air heat exchangers is the finned coil, built up from a circuit of interconnected tube serpentines and fins to increase the heat exchanging surface. Thanks to the combination of key design variables (coil materials, coil geometry, casing design, fan type), air units are very versatile heat exchangers with a great variety of applications in many industries. Alfa Laval supplies finned coil air heat exchanger products for a wide variety of applications.

Air coolers & air-cooled condensers

Air coolers and air-cooled condensers are key components in air cooling and airconditioning systems. On the refrigerant side the most common media are a brine or an evaporating refrigerant like H(C)FC, ammonia or CO2. A chilled brine may be supplied from a chiller that is potentially located far away, but a liquified refrigerant must come from a nearby condensing unit. When an evaporating refrigerant is used, the cooling coil is the evaporator in the vapour-compression refrigeration cycle (‘direct expansion’ or ‘DX’ system).
