Hot water on opening tap. Qm/h ADVANTAGES Water quality preserved: - constant water renewal in rotor chamber ; - choice of materials compatible with network ; - DSB Anti legionella Infection System. Anti-blocking system guaranteeing exceptional resistance to hard water, up to F. Easier choice : - speed, - adaptation accessories enabling replacement without altering the piping. DSB : continued availability of an emergency circulator with perfect irrigation of the domestic hot water loop due to the ALS system. - Simultaneous operation possible in the case of increase in flow rate.

- -S - DSB SECTIONAL DRAWINGS -S Interior of the single circulator - Stainless steel casing proposed on wide diameter apparatus - compatibility with galvanized steel piping. - Ceramic shaft : - constant renewal of water, temperature maintained above the thereshold of lime precipitation. - Stainless steel cartridge and rotor with a stainless steel sleeve. - Integrated and automatic motor overload protection for running security. Twin circulator: principle of the anti-legionella infection system (ALS) (Patent pending). Interior of the single circulator The ALS gives constant circulation and renewal of water in the hydraulic casing of the emergency circulator when its motor is shut down : - no stagnant water (no ox-bow phenomenon); - maintaining a steady temperature between the two circulator units which avoids formation of legionella infection in hot water installations adjusted to a normal operating temperature. - Casing with motor in operation. - Casing with motor shut down - Water circulation in the domestic hot water loop. - ALS water circulation. 9
