Products Applications

This DC power supply enables water electrolysis by converting AC grid/renewable energy into stabilized DC for hydrogen production. Over 75% of green hydrogen projects use this technology, with wind-to-hydrogen rectifiers adjusting 120A outputs within 50ms during wind fluctuations. Balancing dynamic grid stability requirements, these systems sustain the technological backbone of hydrogen economy expansion.

SF6, offering triple air’s insulation strength, powers high-voltage applications like 345kV+ GIS switchgear (200+ kg for arc quenching) and 7nm semiconductor etching (~0.3L gas/300mm wafer). Though its GWP is 23,900× CO₂-equivalent, no alternatives match its compactness for offshore converters or precision in 3D NAND manufacturing. Industry faces a reliability-versus-sustainability dilemma.

Application Industry

*Photovoltaic, wind power, wave power, biomass power(green power) are connected to the power sourcerectifier and the electrolyzer to electrolyze hydrogen production

*Electrolytic hydrogen production by power source rectifer connected to conventional power grid and integrated with electrolyzer

*Inverter system between hydrogen energy storage and power grid

Tetrafluoron, a compressible inert gas lacking color, odor, and flammability, enables material processing including silicon, SiO₂, Si₃N₄, PSG, and tungsten film etching. Its industrial uses span electronic component cleansing, photovoltaic cell fabrication, and precision laser applications. It also plays critical roles in gas-phase insulation, cryogenic refrigeration, space rocket attitude control, and printed circuit board detergent processes.

In the electrolytic synthesis of sulfur hexafluoride, technicians directly add sulfur to a fluorine electrolytic cell, where it reacts to form a KHF₂-HF-S mixture. Subsequent purification steps yield high-purity SF₆. When electrolytically melting this mixture, the fluorine produced immediately reacts with the sulfur in the electrolyte and generates SF6. After adding the sulfur, the electrolytic voltage of the electrolytic cell does not increase, nor does it cause current loss..
