Standard configuration

  • Coil
    An innovative coil design based on 3/8” copper tubes and corrugated aluminium turbo fins provides excellent heat transfer at a minimized refrigerant charge. Standard fin spacing is 2.1 mm. Separate connections provide the opportunity for independent operation of both dry cooler coils. Flanges stainless steel (UNI EN 1092-1).
  • Casing
    Casing material is galvanized steel sheet, pre-painted with an epoxy finish (RAL9002). Separated fan sections.
  • Fan motors
    Fan motors 400/50/3 available in two fan diameters (800 & 910 mm). The motors are with external rotor, protection class IP54 according to DIN 40050. Integrated thermal protection by thermo contacts provides reliable protection against thermal overload. These fan motors are available in five sound level classes: T=high performance, S=standard, L=low, Q=quiet, and R=residential. Motors are wired to one or more common terminal boxes.

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'.
