Hi-Tech Plus Angled Commercial Air cooler for A2L refrigerants
Alfa Optigo SFMS
Alfa Optigo SFMS
Alfa Optigo SFMS is a commercial slim air coolers line suitable for the safe use of ASHRAE A2L refrigerants. A2L refrigerants have a minimal impact on global warming and they will bring maximum energy efficiency. So today, they are the best technological solution for air conditioning and refrigeration applications, outside the natural refrigerants. General applications for Alfa Optigo SFMS are in small to
medium-sized cooling and freezing rooms. All Alfa Optigo SFMS models are characterised by a low silhouette for the efficient use of cold room space.
