Descaler is made of hi-effeniecy magnet power, it can used forboiler, water heater etc. DFT power :3000 GS Flow rate: 800m3 /h Magnetic Water 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 ...
