TETRADOM GMBH is the production and sales partner of WELLAN GMBH. The main products include the Wellan®2000 ring, Power ring, invented by Mr. Klaus Wagner, the founder of Wellan Gmbh. TETRADOM develop the new quantum products based on this technology.
Our products improve the quality of water in purely physical ways and solve problems such as scale, rust, bacteria and algae that have harassed industrial and domestic water for long time. This technology is derived from the study of ultra-fine vibration waves in quantum physics. By empowering special materials to generate special ultra-fine vibration waves, it changes the existence form of scale and rust substances in the water, causing solid sediments to break away from the pipe wall, then be carried away by water. Achieved descaling and removing rust effect …
