Timilge

Timilge Electronic Water Descaler System, Reduces Limescale, Rust, and Minerals, No Chemicals, Easy Installation

Main Highlights

[ Why do you need it ] Normally used city water and tap water contain minerals such as calcium ions and magnesium ions, which are likely to produce insoluble polymers such as calcium carbonate during transportation. After precipitation, they adhere to the pipe wall to form scale, block the pipes, and deteriorate the heating effect of equipment, and rust accumulation, with unpleasant smell
[ How it works ] By conducting complex frequency-modulated electromagnetic signals into the water, when the water flows through the line area, the decomposed water molecules better combine with calcium and magnesium ions to form crystal particles with a smooth surface, which are not easy to adhere to the surface of pipes and equipment.while allowing the existing limescale decomposes slowly
[ Different with salt water softener ] No salt, No chemical involves into your water, No PH changes.Keep the original normal minerals in the water while preventing the formation of scale and the decomposition ,discharge of existing scale
[ Easy to install ] No need to damage the pipeline, just wind the coil outside the pipeline. It is suitable for all kinds of pipelines.This water descaler system should be installed on the main water supply pipe where water enters the building can exert the greatest effect
[ Notices] 1: The high iron level in the water will reduce the effectiveness of the electronic water descaler. For the iron content in the water above 0.3 ppm, recommended to use an iron removal filter before. 2: Operating voltage is 110-120v.3:If the power light does not light up, the internal power cord may fall off, just connect it. In this case, you can contact us at any time
