Main characteristics AlfaBlue BC
- Finned coil
The coil design provides excellent heat transfer at minimal refrigerant charge. Condensers are fitted with aluminium turbo fins and rippled copper tubing. Available fin spacings: 2.1 and 1.8 mm (for 950 mm fan diameter). 2.5 mm available as optional. Copper headers.
Frame construction provides high rigidity for protection against vibration and thermal expansion. Casing and frame made of corrosion resistant pre-galvanized steel, epoxy coated white RAL 9003 on both sides. Separated fan sections.
- Fan motors
High efficiency AC or EC fan motors, available in different fan diameters (800, 910, 950 & 1000 mm) and noise levels, power supply 400/50/3. Motors with external rotor, protection class IP54 according to DIN 40050. Integrated thermo contacts provide reliable protection against thermal overload.

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 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 HFOs, HFCs, 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).
