Standard configuration

  • Coil 
    An innovative coil design provides excellent heat transfer. In standard execution radiators are fitted with smooth copper tubing and industrial power fins for long lasting performance. Available in different fin thicknesses, fin materials, fin spacings and surface treatments. Coil configuration optimized according to liquid flow. Flanges aluminium (UNI EN 1092-4) or stainless steel (UNI EN 1092-1). AlfaBlue Power offers the possibility to have two separate sandwiched coils. This solution is used to combine HT & LT circuits in a single casing. 
  • Casing
    Frame construction provides high rigidity for stability and protection against vibration and thermal expansion. Casing & frame are in Hot dip galvanized steel or Aluzinc. Optional: all casing parts 2-sided epoxy coating. Separated fan sections.
  • Fan motors
    Fan motors specifically designed for outdoor conditions, protection class IP55. Fan diameter 1440 mm, blowing through the coil. Power supply 400/50/3 or 460/60/3. Each motor is completely pre-wired to an isolating switch and fitted with a top protection cover.


For a full overview of all available options and additional technical specifications please refer to the product leaflet.

  • All liquids that do not corrode copper
  • Capacities: 1,180 up to 4,940 kW
    (water, Tair=35°C; Tfluid in/out=90/70°C)

How it works

Alfa Laval 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 Laval 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'.
