Duplex water softeners with electronic timer "SXT"

The water softeners SVFD series duplex volumetric, thanks to the supplied electronic timer mod. "SXT" are automatically controlled water softeners. This type of water softeners is used for utilities with a very variable daily consumption, in cases where it is not possible to install a storage tank. The system can supply softened water at continuous cycle without need of a break for the resins regeneration. This is possible thanks to two pressure wessel made of fibreglass, charged with strong cationic resin in sodium cycle that work in alternation, while one line is in cycle, the other is paused/regeneration. On reaching the set-point, the operating line automatically starts the regeneration cycle and alternates with the other line already regenerated which automatically enters in production. In this type of water softeners the start of the regeneration takes place automatically when reaching the volume of softened water set on the electromechanical timer. Even in the absence of power supply the electromechanical timer continues to count the litres of softened water supplied by the unit.

COUNTER: turbine litre-counter integrated in the centralised valve and complete with cable for the connection to the electromechanical timer.
RESINS TANK: pressure wessel built in non-toxic plastic material and externally reinforced with fibreglass, complete with upper and lower screen for the drainage of cationic resin load supplied in Na+ sodium cycle able to guarantee the cyclic and maximum flow rate. 
SALT TANK: built of rigid polyethylene with high density and complete with separation grid, well, air-check brine valve Ø ⅜” intake pipes of the brine and overflow fitting Ø ½”.

The water softeners SVFD duplex series are prepared for the installation of the automatic device for producing chlorine able to sterilize the resin bed. As required by the Italian Ministerial Decree no. 174/2004, all components of the hydraulic circuit are non-toxic and made using materials suitable for contact with drinking water. The duplex water softeners of the series SVFD are units for the treatment of drinking water and conform to the Italian Health Ministry’s Decree no. 25/2012 and EC standards. Warning: these appliances require regular and periodic maintenance in order to ensure that the water treated meets drinking water standards and that the improvements as stated by the manufacturer are preserved.
