The range of Alfa LU-VE Optigo SFMD commercial air coolers with dual air discharge, designed for use in small to medium-sized cold rooms and freezer rooms. Their low noise level makes them particularly suitable for temperature-controlled working and processing areas. These flat-type coolers are compatible with refrigerants from safety groups A1 and A2L, and offer nominal cooling capacities ranging from 1.47 kW to 14.57 kW under SC2 conditions. Standard models are equipped with energy-efficient EC fans (Ø 350 mm), which blow air through the finned coil block. The maximum allowable design pressure is 24 bar. High performance levels, in compliance with European and international standards, are certified by Eurovent.
