Optigo SFMS

Optigo SFMS

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 Optigo SFMS are in small to medium-sized cooling and freezing rooms. All SFMS models are characterised by a low silhouette for the efficient use of cold room space.

The Optigo SFMS series machines use the same heat exchange components as the corresponding Optigo FMS series models and provide the same performance. The Optigo SFMS series machines can work with HFC category A1 refrigerants.

How it works

Alfa LU-VE finned coil air heat exchangers have been designed to achieve an optimized exchange of thermal energy between air and a refrigerant or fluid. The ‘heart’ of our air heat exchangers is the finned coil, built up from a circuit of interconnected tube serpentines and fins to increase the heat exchanging surface. Thanks to the combination of key design variables (coil materials, coil geometry, casing design, fan type), air units are very versatile heat exchangers with a great variety of applications in many industries. Alfa LU-VE supplies finned coil air heat exchanger products for a wide variety of applications.

Air coolers & air-cooled condensers

Air coolers and air-cooled condensers are key components in air cooling and air conditioning systems. On the refrigerant side the most common media are a brine or an evaporating refrigerant like HFO/HFC, ammonia or CO2. A chilled brine may be supplied from a chiller that is potentially located far away, but a liquified refrigerant must come from a nearby condensing unit. When an evaporating refrigerant is used, the cooling coil is the evaporator in the vapour-compression refrigeration cycle (‘direct expansion’ or ‘DX’ system).
