arago scale remover

Our innovative water treatment solution stands out for its unique, certified efficiency. It offers an ecological and economical alternative to traditional salt water softeners. Thanks to our cutting-edge technology, we are able to dissolve limescale, even present in large quantities in the hardest water (high TH), without altering the mineral quality of the water. By eliminating limescale deposits, our solution protects your household appliances, reduces your energy consumption and guarantees optimum comfort of use on a daily basis. What's more, our process generates no waste and respects the environment.
It's the best alternative to salt water softeners.

F.A.Q.

The company is based in Geneva, but covers the whole of Switzerland thanks to its network of partners.

The company has specialized in physical water treatment since 2015.

The technology originated in Austria, and was developed by scientist Victor Schauberger in the 1920s.

The first system was conceived in 2009, before taking on
colossal scope in the water treatment market in 2011.

We guarantee delivery within 2 to 5 working days, depending on the
diameter or quantity of systems ordered.

Machining and assembly are carried out at the Brindisi plant in
Italy and the Colmar plant in France.

On average, we install 500 systems a year, with over 5,700 installations in Switzerland to date, and
still running.

It's the implementation of a treatment solution against limescale or corrosion that doesn't require any chemical products, and doesn't modify the water's chemistry.

All our products are guaranteed for 10 years from the moment they are installed in the hydraulic system.

Building / condominium

Are you a building owner, technical manager for a real estate company, or responsible for managing a real estate portfolio?

Is your building starting to age faster than expected? Are you sending more and more work orders to plumbers/heating engineers for repairs? Are recurring problems gradually starting to pile up? Are maintenance costs increasing every year?

  • Preserve the service life of pipes (hot water columns).
  • Significantly reduce maintenance costs related to limescale (e.g., descaling water heaters).
  • Provide additional comfort to owners/tenants (zero limescale buildup).

Industry

Are you responsible for the maintenance and operation of an industrial building?

Do your chilled water systems become clogged more quickly due to high levels of corrosion? Do your heat exchangers become scaled too often? Does your technician spend much more time on maintenance than on carrying out the work?

  • Significantly reduce maintenance.
  • Improve your energy efficiency with high-quality water.
  • Limit the use of chemicals to meet environmental standards.

Developer

Is your real estate project the construction of a group of villas or buildings?

You cannot offer salt softeners because they require too much maintenance once installed. Would you like to receive fewer service calls because your heat pumps are failing due to oxidized water, or your boilers are wearing out prematurely due to accelerated scaling? 

  • Protect your plumbing system.
  • Offer a zero-maintenance technical solution for your end customer.
  • Enhance your environmental quality label.

Engineer / design office

Are you developing HVAC projects in the commercial, residential, or industrial sectors?

Is the problem of network sludge build-up recurring despite filling with demineralized water using a Purotap cartridge and excessive maintenance of the sludge pot/magnetic filter? Is your customer complaining about excessive and costly maintenance despite your preliminary study?

  • Maintain the energy efficiency of your hydraulic system.
  • Protect components such as transmitters against corrosion.
  • Significantly reduce maintenance and related costs.

Individual

Do you own an apartment or a house?

Is limescale becoming a daily problem? Do you find yourself constantly cleaning with chemicals? Are your household appliances/sanitary facilities breaking down? Did your last plumbing repair cost you a fortune?

  • Reduce limescale deposits by 100%.
  • Getting rid of your old salt water softener.
  • Enjoy high-quality, non-softened mineral water.

PORTHOLE

NYON, Switzerland

Already having a salt softener, the technical manager
informed us of excessive salt consumption
. He wanted to regulate this consumption or even eliminate it entirely in order to save money.
Our vortex anti-scale solution was installed after
the salt softener with a bypass kit, in order to make the transition gradually and to continue using their current chemical solution
.
