Yueyang Lvdun Environmental Protection Technology Co., Ltd. is a national high-tech enterprise focusing on purely physical treatment of circulating cooling water. We are committed to providing customers with global leading overall solutions in the field of "industrial circulating cooling water treatment".

Green Shield Environmental Protection takes the green revolution of circulating cooling water treatment as its own responsibility. Since 2007, experts and scientific research institutes from the United States, Hong Kong, Taiwan, China and the mainland have gathered together to carry out joint research on high-energy physical water treatment technology. After six years of engineering application testing and improvement, the "whole process physical water treatment technology based on high voltage static electricity" developed by the project was registered as a business entity in 2013, and a production base was set up in China Aviation Development Changjiang Machinery Factory in Yueyang, Hunan Province. In June 2020, the production base of Yueyang Lvdun Environmental Protection Technology Co., Ltd. Will be relocated to the military civilian integration industrial park in Chenglingji New Port District, Yueyang.

"Whole process physical water treatment technology based on high voltage static electricity" has been used in hundreds of circulating water systems in large-scale petrochemical industry, waste heat power generation industry, refrigeration industry, etc. For many years. Practice has proved that in the field of using physical method to treat large flow circulating cooling water, the "whole process physical method based on high voltage static electricity" water treatment technology is one of the few truly effective technologies in the world today.
