Magnetic Descaler The magnetic field strength must be at a surface Gauss level (3000GS-10000GS) This is a physical water conditioning system that uses magnetism. Prevents rusty water and prevents the growth of an removes rust, scale, and water deposits. Just needs to be installed outside the piping. Features Simply installed around the outside of the piping. (However, the effect is good when the piping is non-magnetic (SUS, copper, PVC, etc.) Magsuin contains a powerful permanent magnet, so it can be used semi permanently without an external power source. Improves water quality without using chemicals, so there is no worry about secondary pollution. Since it is installed outside the piping, it is maintenance free
