The range of Alfa LU-VE Optigo FMDW glycol air coolers with two-way air flow, designed for applications in small and medium-sized cooling rooms and freezers. Flat coolers with low noise level operating in the capacity range from 1,20 kW to 17,00 kW.

They are equipped with energy-saving EC fans with a diameter of 350 mm. Maximum operating pressure – 12 bar.

All models of Optigo FMDW range are equipped with slotted aluminium fins that increase the heat transfer coefficient and efficiency, even in frosty conditions. They are completed with corrosion resistant double epoxy coated aluminium body and metal fan mesh. An additional metal seal between the cooler and the ceiling facilitates cleaning of the device.

It is recommended to use an electric defrost system (E) in cooling chambers where temperature is below 4°C. The stainless steel defrost elements are connected to a separate terminal box.

Each heat exchanger is tested for leaks with dry air.

Durable galvanized steel casing, powder coated RAL 9003.
Dismountable and openable casing for cleaning and inspecting purposes.

Drip tray can be opened from both sides, which makes it easier to drain condensate.

Additional protection between air cooler and ceiling makes it easier to clean the device.
