WIKA Mobile Control | Double the Safety for sf6 gas Gas Dehydration

The process is simple: The GAD-2000 automatically takes out the insulating gas gas from the system, dries it independently and returns it to the gas compartment dehydrated. The highlight of GAD-2000: in contrary to standard systems on the market, the switchgear does not have to be disconnected from the mains during the process of gas dehydration! This reduces service efforts and maintenance costs as well as avoiding dangerous load distribution risks.Get price
