AlfaBlue BD

AlfaBlue BD

The AlfaBlue BD series is a wide range of heavy-duty dry coolers. Dry coolers are often used for cooling down condenser water in air conditioning and refrigeration installations. In the processing industry, dry coolers are suitable for closed circuit cooling of various process liquids. With a wide range of sound pressure level alternatives, these units are particularly suited to demanding, noise sensitive environments.

Main characteristics AlfaBlue BD

Standard configuration

  • Coil
    Innovative coil design provides excellent heat transfer. In standard execution dry coolers are fitted with smooth copper tubing (BD) or stainless steel tubing (BDY). Dedicated series for compressor oil cooling (BDO).
    Fins in aluminium or sea water resistant aluminium alloy available in different fin thicknesses and fin spacings, available in two fin designs:
    • Turbo fins for maximized capacity
    • Industrial power fins for long lasting performance
    Coil configuration optimized according to liquid flow. Available either in single (M) or dual (D) fan row: separate connections in the D series provide the opportunity for independent operation of both liquid cooler coils.

  • Casing
    Frame construction provides high rigidity for protection against vibration and thermal expansion. Casing and framework of corrosion resistant pre-galvanized sheet steel, epoxy coated white RAL 9002 on both sides. Separated fan sections.

  • Fan motors
    High efficiency AC or EC fan motors, available in different fan diameters (800, 910 & 1000 mm) and five 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'.
