Pump set made up of two pumps whose deliveries all flow into a common manifold (pumps in parallel). We conceived e.sybox according to our idea of ergonomic technology* and we have developed it enclosing and expressing all the DAB technological know-how based on 37 years of experience in the mechanics and electronics sector. A new PATENTED milestone of DAB evolution. The result is a system, the only one of its kind, efficient, compact, easy to use and satisfactory for the installer as well as the final user. Thanks to these features, the e.sybox is the most evolved ergonomic system in the world in the field of water pressurization for domestic and residential use.
