The range of Alfa LU-VE FMCX commercial air coolers with single-side air flow, designed for use in small and medium-sized refrigeration and freezing rooms. These units are suitable for operation with the natural refrigerant CO₂, with a maximum allowable design pressure of 60 bar (85 bar available upon request for special versions). The series covers a nominal cooling capacity range from 1.21 kW to 20.60 kW and is Eurovent certified.

Optigo FMCX Equipment:

Fans

From 1 to 4 fans equipped with high-efficiency AC or EC motors, available in 3 diameters (275, 315, and 350 mm), drawing air through the finned coil block. Models Optigo F31MC and F35MC feature external rotor motors. Power supply: 230/50–60/1. All fan motors are wired to a central terminal box.

Air intake through the coil block ensures

  • Better air distribution through the block surface, result in better heat exchange
  • Longer air flow
  • Accumulated frost is visible on the air intake side

Each heat exchanger is leak-tested using compressed dry air and delivered pre-charged with dry air. Suction connection with Schräder valve provided for testing purposes.

Casing
