Vulcan: The revolutionary alternative to water softeners

Swimming pools and spas are complex systems that demand rigorous cleaning efforts and complicated water treatment procedures.

The pumping and filtration systems of pools and spas are particularly sensitive to scaling.

Cleaning these consumes tremendous amounts of time and money on a daily basis. Vulcan reduces the cleaning for pools and spas, the water line, tiles, grids, floors and pool walls.

Benefits for your pool or spa

  • Reduction of scale deposits in the whole pool and spa system
  • Longer life and improved performance of filters and pumps
  • Reduction of chemicals that control bacteria and the pH-levels
  • Extensive reduction of cleaning efforts
    Heat exchangers operate more efficiently

Improved water quality

Improved water quality Pools are half-open loop systems which suffer constant water loss as the pool water evaporates. The water demands constant maintenance and chemicals need to be added to keep bacteria, algae, and air quality in compliance with standards. Vulcan improves the water quality and with this the effectiveness of certain substances. Vulcan reduces the cleaning effort for the pool itself, the water line, for tiles, grids, floors and walls.


In an ideal setting, Vulcan should best be installed before the heat exchanger. If possible, the placement should also be after the filters, for example, a sand filter, active carbon filter, etc.
