The device made of permanent magnet is especially effective in preventing boiler pipes from being covered with fur as its strong magnetism changes physical characters of water.

Its installation reduces fuel consumption by 5 to 20 percent and does not need reagent, salt and cation-exchange resin when cleaning pipes.

The device has already been introduced in boilers at the February 8 Vinalon Complex, the Hungnam Fertilizer Complex and other industrial establishments to help operate them at full capacity.
