SF6 gas is a good electrical insulator. SF6 gas can not only provide insulation, but also ensure the stable operation of the equipment under the normal pressure level that cannot be provided under vacuum. On the other hand, the SF6 gas can cause a greenhouse effect. If these gases are put into the atmosphere, it will cause great harm to the environment. Therefore, this gas must be handled properly.
This series of SF6 gas processing equipment uses high-pressure liquefaction and air-cooling technology to store gas in the form of liquefied gas, which is safe and not easy to leak. The recovered SF6 gas dust content is less than 1 micron. The power of the equipment can be adjusted according to your needs.

Advantages of SF6 Gas Refilling Device
Advanced design, full function, and compact structure with the simple operation;
Compressed systems: it takes a closed compressor to ensure no leakage;
Vacuum systems: it takes the rotary vane vacuum pump to prevent oil from returning;
Purification systems: Equipped with Ingersoll Rand filters that take electric heating and highly efficient adsorbents. Without frequent replacement of the adsorbents, so the purification result is better;
Electric systems: Equipped with automatically confirmation three-phase power devices, failure protection;
Control systems: the valves take the latest technology;
Storage system: Provide the storage tank according to users’ requirements;
This equipment is a mobile type.
Application of SF6 Gas Refilling Device
SF6 Gas Handling and Refilling Machine widely used in SF6 gas-insulated electrical equipment factory, use, operation, scientific research departments, and so on, to create a vacuum for a variety of electrical equipment, and fill electric equipment with SF6 gas, and recover SF6 gas from the use of test equipment, then fill to storage tank after purifying and compressing. The recovery device is suitable for SF6 electrical appliances and GIS combined electrical apparatus. The gas recovery unit of SF6 is based on the standard of DL/T662-2009 “SF6 gas filling and recovery device”, which consists of a recovery system, an inflating system, a vacuum system, and a purification system and gas storage system.
So far, our company has sold over 15,000 sets of China oil purifier brand oil purifiers, which are widely used in power electric, metallurgical, petrochemical, mechanical, military industry, railway, light industry, and other industries. In addition to the SF6 gas refilling device, we also provide Lube Oil Purifier. If you have any needs or questions about China oil purifier’s oil purifiers, please contact us.
