The Optigo FCC Alfa LU-VE series of commercial air coolers with one-way air flow designed for applications in small and medium-sized refrigerated and freezer rooms. Models designed to operate with HFC refrigerants, with nominal capacities ranging from 5.4 to 60.4 kW (SC2, R404), and equipped also with 10 mm fins, are ideally suited for industrial applications. Certified Eurovent devices.

The maximum allowable working pressure is 24 bar (for fluid of group HFC).

Currently, work is underway to prepare technical information for this series of air coolers. If you have any questions regarding the selection of Optigo FCC models, please contact our sales departments.

Standard configuration:

  • High-efficiency heat exchanger made of copper tubes with internal rifling and aluminum fins.
  • Standard fin spacing: 4.5, 6.0, 7.5, and 10.0 mm.
  • Optigo FCC air coolers come with 1-4 fans equipped with high-efficiency AC or EC motors.
  • Two fan diameters (450 and 500 mm) that draw airflow through the coil.
  • Sturdy housing made of galvanized steel with RAL 9003 powder coating.
  • The housing is detachable and opens for cleaning and inspection. Equipped with a drain pan for collecting drips.
  • Each heat exchanger is pressure tested with dry air and delivered pre-charged with dry air. A Schrader valve is installed on the suction pipe for testing purposes (only for models with HFC and CO2).
