The Culligan HE GREY TWIN water softener, designed to satisfy the most varied professional and semiindustrial requirements, is a specific device for removing hardness (Calcium and Magnesium), by means of exchanger resins that are selected and suitable for contact with water and are foodsafe, such as Cullex strong cation exchange resins in a sodium cycle, normally able to be regenerated with sea salt. The vertical cylindrical-shaped container is made of fiberglass reinforced corrosion-resistant material. The water softener offers savings on costs and at the same time is environment friendly, the technologies patented by Culligan optimize the consumption of salt, water and electricity for up to 46% in savings. The softener is able to supply treated water continuously 24 hours a day. Two independent columns produce a continuous flow of softened water; when the exchange capacity of one of the containers is exhausted, the second one comes into service while the first one is regenerated. HE TWIN water softeners are equipped with a single GBE control unit installed in the main control valve. The Culligan Dial-a-Softness® control system enables selecting the hardness of the water for the service without an additional external mixing device. The exclusive Culligan Soft-Minder® monitors the daily use of water by flow meter and offers an advanced diagnostic program. It allows the regeneration program to be started according to: volume of treated water timed volume of treated water with timed regeneration (domestic volume) The exclusive control valve, which uses motor pistons, offers more reliability than conventional rotating valves. The design of the valve with several pistons means easier maintenance and longer life. The brine container made with corrosion-proof components and the Dubl-Safe system that controls the level and the quality of the brine ensure perfect functionality. Moreover, the control valve is fitted with an automatic bypass system to supply untreated water to the service even when the water softener is being regenerated.
