Water treatment

Magnetic scale inhibitors

Magnetic scale inhibitors, or ionic accelerators, prevent calcium and magnesium ions from bonding with carbonates, thus preventing the formation of limescale. They operate with a permanent magnet, with no electrical connections, no maintenance and no running costs.

  • From 1/2" to 4" and beyond
  • No electrical power
  • Maintenance-free
  • Brass, aluminium or AISI 304 stainless steel

Limescale

Effects of limescale

Hardness is the quantity of calcium (Ca++) and magnesium (Mg++) salts dissolved in water. In very hard water these ions bond with other substances to form a precipitate, limescale; the phenomenon increases as temperature rises.

1

Clogged pipes

Over time limescale reduces the effective bore of the pipes until it blocks them.

2

Loss of efficiency

Deposits thermally insulate heating elements and heat exchangers: just one millimetre of limescale reduces the efficiency of a heating or cooling system by 10 – 20%.

3

Bacteria and biofilm

Limescale is an ideal substrate for the deposition and proliferation of bacteria and microorganisms, which form biofilm on the inner walls of the pipes.

4

Stains and appliance wear

Hard water leaves stains on shower screens and tableware and increases the risk of faults and the need for maintenance of household appliances, boilers and radiators.

Operation

Operating principle

1

Magnetic field

Installed on the pipe with negligible pressure losses, it forces the water through an intense magnetic field generated by a permanent magnet, with no need for electrical connections.

2

Aragonite, not limescale

The magnetic field causes a molecular dissociation of the hardness salts (calcium and magnesium ions), turning them into a soft, powdery, talc-like precipitate called aragonite, which remains in suspension.

3

Hardness unchanged

Unlike ion-exchange softeners, it does not reduce water hardness, but prevents it from precipitating and building up as limescale. Once installed it requires no maintenance and has no running costs.

Applications

Applications

It can easily be installed on any system, upstream of each point of use, as required.

Water supply networks

Downstream of the storage reservoirs of large public water supply networks, on the pipes distributing water to users.

Homes

Downstream of the water meter, to protect the entire plumbing system and household appliances.

Heating

In the heating circuit, as additional protection for the boiler, radiators and the entire system.

Industry

In industrial plants, both on the water supply line and in the circuit.

Diagrams

Installation diagrams

It is fitted directly in the circuit, with the same diameter as the pipe, or in by-pass (recirculation) with a smaller diameter.

Versions

Materials and versions

Depending on the application, they are made of chrome-plated brass, Anticorodal aluminium or AISI 304 stainless steel machined from solid.

Chrome-plated brass and Anticorodal aluminium

With threaded or flanged connections, for residential, domestic water and industrial applications.

Stainless steel magnetic scale inhibitor machined from solid

Stainless steel machined from solid

Single-piece body in AISI 304 stainless steel, designed for the most demanding operating conditions: high-pressure pipes, brackish or acidic water. The water never comes into contact with the magnets: the internal ones are protected by AISI 304 stainless steel, the external ones by hard-anodised aluminium.

Stainless steel magnetic scale inhibitor with internal helical insert

Helical insert

In the stainless steel version a helical insert coaxial with the magnets imparts a swirling motion to the water, so that the entire volume passes through the magnetic field and the treatment is as effective as possible.
