- The SF6 tank can withstand pressures up to 5.0mPa, and the SF6 gas can be recovered to a final vacuum of 1 mbar to 5 mbar, which far exceeds the IEC 62271-4 regulations. This type of equipment is equipped with semi-automatic controls and is easy to operate.
- Our SF6 extraction and aeration equipment can dry, filter, and liquefy SF6-gas to refill internal storage tanks and external SF6 gas cylinders through high-performance and efficient processes.
Description of SF6 Gas Recovery Unit
About SF6 gas
SF6 gas is a good electrical insulator. SF6 gas can provide insulation and ensure the stable operation of the equipment under the normal pressure level that cannot be provided under a vacuum. On the other hand, the SF6 gas can cause a greenhouse effect. If these gases are put into the atmosphere, they will cause great harm to the environment. Therefore, this gas must be handled properly.
About the SF6 gas recovery machine
QTHS-1 series SF6 gas recovery and filling machine is used in the manufacture, use, operation, scientific research, and other departments of SF6 gas-insulated electrical equipment. The SF6 gas was recovered from the tested electrical appliances, and at the same time, it was purified and compressed, and stored in a storage tank. The recovery and purification charging and discharging device are suitable for SF6 electrical appliances and GIS combined electrical appliances.
The tank and purification system of the QTHS-1 series SF6 gas recovery and filling machine are composed of a built-in renewable dry filter, dust filter, ball valve, vacuum gauge, electrical control, control of pressure detection and alarm device, instrument panel, and other auxiliary facilities.

Advantages of SF6 Gas Recovery Machine
SF6 is commonly used in power applications and is used worldwide in high-voltage circuit breakers, metal-enclosed switch cabinets, linear accelerators, high-voltage transformers, capacitors, and gas-insulated circuits. Due to the special application of gas, there should also be a standardized process for recovering SF6 gas.
Our product provides the function of recovering and refilling one air chamber while emptying another air chamber. Our SF6 gas recovery unit uses completely dry compressors and vacuum pumps. The SF6 treatment and recovery device has high safety and reliability in the treatment process and can recover, purify and supplement SF6 gas.
