How it works

Alfa LU-VE 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 LU-VE supplies finned coil air heat exchanger products for a wide variety of applications.

Air-cooled liquid coolers (radiators/dry coolers)

Air heat exchangers may be used to cool various process liquids. For this application hot process liquid flows through the tubes. This liquid is cooled by the relatively cold ambient air that is forced through the coil.
Air heat exchangers for process liquid cooling are referred to as 'radiators'. Air-cooled liquid coolers for HVAC applications and total energy systems are referred to as 'dry coolers'.
