New generation high performance water softener with innovative design and down flow regeneration to minimize water and salt consumption. The bucket consists of 2 independent bodies and the resin tank is completely isolated from the brine tank. It is possible to install both parts as independent bodies. The softener consists of a GRP tank with top/bottom dispensers and a polyethylene cabinet. The compact softeners can be operated with a BNT-1650F automatic valve with a new generation controller with multi-language display and visual interface.
