GP has long cooperated with mainstream enterprises in new materials and energy industries to provide one-stop gas supply services for major domestic environmental protection companies, emerging materials companies and photovoltaic solar companies. For this purpose, it develops and installs high-purity EP-grade gas cabinet  (GC) and valve manifold box  (VMB), and provides experimental gas distribution for its corresponding inspection and testing departments and development and design departments. The gas rack (GR) and valve manifold panel  (VMP) of the jacket are also developed according to the actual characteristics of various factories, and the dangerous gas management system (GMS) is customized to protect the safe production of the factories. The tail gas treatment system of the above-mentioned production equipment has been developed accordingly, which ensures that the discharge of factory exhaust gas meets the standard.
