GENERAL The Culligan Ultra Line softeners range, for its exchange capacity and flow rates, fits with small and medium industry needs. This series includes many models and a wide range of capacities, as well as a range of accessories, which are up to personalize the unit according the customer’s needs. When softened water is also intended for food purposes (hotels, tourist resorts, commercial and residential centres, etc.), a dosing pump will be coupled with the softener for the automatic disinfection of resins, according to the Ministerial Decree N° 443 – 21/12/1990. The regeneration can be started according to different criteria: the Culligan expert will help you in choosing the one fitting to your needs. As default: • time-clock control: an electronic card starts the regeneration at pre-set time intervals. As option: • volume control: a device (including a flow-meter) starts the regeneration after a pre-set volume of water treated. • alternate regeneration: the volume control principle can be applied to two softeners operating in alternance. The softened water supply to the service is uninterrupted. • Quality control: a device which “senses” the product water quality and starts the regeneration whenever necessary. CONSTRUCTION FEATURES The tank is made of steel and it is protected internally by a food-grade layer of epoxy resins of controlled thickness and covered externally by a enamel paint.
