In January 2020, three people from the R&D team of CRRC electric locomotive Research Institute came to our company from Zhuzhou, Hunan Province, and used our testing platform to conduct a comprehensive test and verification of our gas water separation filter products. They successively carried out waterproof test, sand prevention test, moisture-proof gas test, dust-proof test, and wind resistance test. The experimental test was very successful. CRRC R&D personnel were very satisfied with the performance indicators tested, And a detailed experimental test report has been formed. The R&D team of CRRC has conducted in-depth technical exchanges with our technical personnel, pushing the cooperation between our company and CRRC China to a deeper level. The success of this experiment also means that our innovative products will be applied to more business sectors of CRRC China. We look forward to win-win cooperation and create brilliance together!
