GDQC-300C gaz sf6 Gas Recycling Solidification Purification

Product Description. GDQC-300C sf6 gas Gas Recycling Solidification Purification system is used to separate the air, CF4 and low fluoride decomposition from Sulfr hexafluoride gas. The separation system is based on the principle of high voltage oil free direct liquefaction, carry out initial liquefied filtration of all regenerated and processed insulating gas gas, and then carry out further liquefaction of the gas/liquid mixture in the separator by cryogenic cooling system.Get price

EPRI’s SF Management Program

Although pure sf6 gas is chemically inert and safe to handle, many of its decomposition products are corrosive and toxic. Their accumulation in gaz sf6 equipment raises concerns about equipment reliability and personnel safety during maintenance procedures and cleanup of faulted equipment. sf6 gas also has properties that may impact the environment. The Kyoto Accord identified itGet price
