Main characteristics AlfaBlue Reverse BR
An innovative coil design provides excellent heat transfer. In standard execution BR radiators are fitted with smooth copper tubing and industrial power fins for long lasting performance. Fin spacing 2.1 to 3.6 mm. Fin thickness gradually increases from standard thickness at 2.1 mm fin spacing to double fin thickness at 3.6 mm spacing. Coil configuration optimized according to liquid flow. Separate connections in the D series provide the opportunity for independent operation of both coils. Flanges aluminium (UNI EN 1092-4) and stainless steel flanges (UNI EN 1092-1).
Frame construction provides high rigidity for stability and protection against vibration and thermal expansion. Casing & frame of corrosion resistant pregalvanized sheet steel (corrosion resistance class C4). Mounting feet galvanized steel. Separated fan sections.
- Fan motors
Fan diameter 910 mm, blowing through the coil. Available in four noise levels, power supply 400/50/3. Motors with external rotor, protection class IP 54 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-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'.
