SERVODRY -SDA Zero Purge Dryer
The Servodry Zero Purge external heat adsorption dryer guarantees a stable dew point down to -40°C, with a version available to reach -70°C under pressure. Thanks to its robust design and regeneration controlled by a variable frequency blower, it offers one of the best energy efficiencies on the market.
The range includes 15 models and covers flow rates up to 9,500 m³/h.
The new generation of SERVODRY® SDA adsorption dryers builds on the continuous development of proven drying technologies. Thanks to the integration of advanced control systems and the ongoing optimisation of drying processes, this range sets a new standard in the market, offering superior technical performance.
Each component is selected with absolute priority given to reliability and durability. Only recognised German and European manufacturers who meet strict quality requirements are used. This approach guarantees an exceptional level of operational safety, remarkable reliability and particularly low energy consumption.
A real asset for any compressed air station seeking to combine efficiency, cost control and sustainability.
