Water softening is the process of removing the hardness, caused by Calcium and Magnesium salts, and exchanging them with Sodium salts, which do not deposit scale.
To obtain the exchange the water flows through a bed of resin that has been previously charged with Sodium Chloride (table salt). The Cullex Culligan exchange resin is suitable for contact with food, has high resistance to mechanical shock, long life, high exchange capacity and low consumption of salt. The closely controlled resin bead size minimises the pressure loss.
All Culligan softeners are completely auto-matic, and the different working phases (service, backwash and regeneration) are controlled by an electro-mechanical or electronic control board, that activates a valve or a group of valves, depending on the model. The automatic phases may also be controlled by a metering device (optional) that activates the regeneration phase according to the quantity of water dispensed.
In the "Duplex" version the stand-by softener is automatically connected to service when the first softener exhausts its exchange capacity, allowing it to regenerate, while the combined unit provides a continuous flow of softened water. The "Extra Recharge" device makes it possible to manually activate the recharge without disturbing the automatic phases of the working cycle. Each Culligan softener may be equipped on request with an automatic disinfection system. NOTE: with the use of appropriate selective resins, the Ultra Line softener may be converted into a Nitrate removal unit, whose choice and size must be decided at the headquarters

The Gold series of water softeners are electronic, fully automatic and equipped with a motorized control valve. The fully programmable Accusoft® microprocessor offers easy data entry performance options,to meet individual needs. The Gold series features an exclusive "Quadra-Hull®" vessel for protection, consisting of four layers: a food- grade liner, a composite shell, reinforced with two-component epoxy resin, a lightweight carbon material, exceeding in strength the existing metal materials and the tank jacket, which is corrosion-proof and U.V. resistant.
The electronic board allows for easy set up and flexible operation, as well as the set up and retrieval of important information about the operation of the unit. The built-in by-pass makes the installation easier, and the water meter kit (optional) allows volumetric regeneration, saving salt and water.
The unit is equipped with an electronic controller allowing simple time-clock or volumetric regeneration. In the duplex operation, a stand-by softener is automatically started when the first starts regeneration.
The cycles are controlled by a motorized valve. The electronic board allows an easy and flexible operation, as well as storage and retrieval of important information about the operation of the unit.
ULTRA LINE HA/HB
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 layer of enamel paint. The harness is in corrosion-proof PVC Noryl. Ultra Line HA softeners are available in tanks ranging from 200 to 1400 mm in diameter. For tanks with diameter 770 to 1550 mm, it is available also a HB version, with a larger harness, in order to facilitate higher service flow rates.
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 layer of enamel paint.
The cycles are controlled by diaphragm valves, made of epoxy painted cast-iron. Ultra Line HB softeners are available in tanks ranging from 1700 to 6600 mm in diameter. The regeneration can be programmed either on a time-clock or on a volume basis. In volumetric mode a water meter measures the volume of treated water, and an electronic control board starts regeneration once the pre-set volume is reached. Two control boards are available: one for the control of a single softener (PLF 2K Model) and the other for the control of two alternating softeners (PLM 2K Model).
