Main characteristics Alfa-V VLD
Optimized coil geometry provides excellent heat transfer, low pressure drop and low fouling thanks to the smooth fins and the large air passage. By default, fins are in Industrial aluminium. Piping material: copper ø 12 mm (VLD), copper ø 16 mm (VLD6) brazed to copper manifolds and stainless steel (VLDY) TIG welded to stainless steel manifolds. Flanged connections PN10/16 according to EN1092. Manifolds equipped with venting and draining nozzles, on request with manual ball valves.
Construction provides high rigidity to withstand vibrations, thermal expansion and rough environmental conditions. Casing, supports and frame made of corrosion resistant hot-dip galvanized steel plates, class C4-H as basic level. Alfa LU-VE design fan-collars made in composite material to optimize air distribution increasing performance and reducing energy consumption and noise level.Separated fan sections.
- Fan motors
Squirrel-cage electric motors, designed exploiting decades of experience in outdoor use. Built to IEC standard 6, 8, 10 or 12 poles, provided with: condensing water outlets, shaft seals and H-class insulation. Construction optimized for use on air heat exchangers. Motors pre-wired to lockable service switches placed outside the fan-collar. Available for various power supplies (std 400/3/50, 460/3/60). Impellers ø 1.5 m are made in high efficiency aluminium wing-blade profile for reduced power consumption and noise emissions.

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'.
