  1. Features of product
  • Integrated design
  • Easy to move and operation
  • Reliable and safe
  • Qualified design and outlet water quality
  • Error alarm
  1. Advantages of product
  • High efficiency: The overall design of the water softener is reasonable, so that the effective working exchange capacity of the resin can be brought into full play.
  • Provincial labor: high degree of automation, no need to set up a special person on duty.
  • Water saving: The water production rate of the water softener is over 98%.
  • Power saving: The principle of siphon regeneration is adopted, no salt pump is needed, and the power consumption is only 1% of manual soft water equipment.
  • Small footprint: Only the footprint of the resin tank and salt tank is needed to save the space occupied by pipelines and salt pumps.
  • Easy to adjust: Users can adjust the regeneration cycle and regeneration time according to actual needs.
  • Low operating cost: Due to the high degree of automation, the water softener can adapt to changes in water volume, accurately measure the amount of water produced and the amount of regenerant, avoid innocent waste of regenerant during regeneration, and save a lot of labor costs.
  1. Applications of product


  1. Precautions of product
  • The equipment should be installed in a clean and dry place, the temperature should be above 0 ° C, to prevent the resin inside the equipment from being frozen or the internal parts rusting to cause equipment failure. At the same time, regular cleaning and maintenance should be performed during use to keep the equipment clean and running normally.
  • Before operating the equipment, check and tighten the fixing bolts on all equipment. The bolts must not be loose. Make sure that the shell of the switchboard is grounded. If possible, separate the switchboard from the equipment and be careful not to connect the wrong wiring number.
  • When the equipment is running, do not adjust the time relay. Always turn off the power when servicing and cleaning the equipment. Water and electricity are supplied at the same time when the equipment is running, and water and electricity are cut off at the same time when the equipment is stopped.
  • If the water contains a large amount of sediment, carry out sedimentation treatment before entering the softening equipment
  1. Product maintenance
  • White disassembly and clearing once a year
  • Disassemble the boiler water softening equipment once a year, clean up the impurities in the upper and lower water distributors and the quartz sand cushion, check the resin loss and exchange capacity, replace the severely aged resin, and use hydrochloric acid solution to recover the resin poisoned by iron. .
  • long-term decommissioning, wet maintenance of resin
  • Especially before the boiler is softened for a long time, the resin should be fully regenerated once, and the resin should be converted to sodium type for wet maintenance.
  • Resin must be sterilized
  • If moldy resin is found, it can be sterilized. Generally soak in a 1% formaldehyde solution for several hours, then rinse with water until no formaldehyde odor.
  • When the boiler water softening equipment is stopped in summer, the water softener is cleaned once a month
  • When discontinued in the summer, the water softener should be flushed at least once a month to prevent the growth of microorganisms in the exchange tank and the resin to mold and agglomerate.
  • When the boiler demineralized water equipment is stopped in winter, take measures to prevent frost.
  • In winter, when the boiler demineralizing water equipment is disabled, antifreeze measures should be taken to prevent the resin from expanding and cracking due to freezing. The resin can be stored in a saline solution, and the concentration of the brine should be prepared according to the temperature conditions.
