The PureTech SF6 Gas Recycling and Filling Machine (Model GRF) is also called as SF6 Gas Recovery and Refilling Machine and SF6 Gas Purification Machine, it is designed for circuit breakers, GIS, transformers, and other electrical equipment. After electrical equipment is evacuated, SF6 gas is filled inside, and recovered from the electrical appliances in use or test, purified and compressed and stored to storage tank at the same time.
Model GRF it is composed of vacuum system, compression system, purification system, storage system, condensing system and re-filling system.
• Adopt Germany technology with advanced design, rational construction and easy operation. Two stage rotary-vane vacuum pump with fast pump rate and also equipped with oil back-flow prevention device.
• Faster vacuum pumping speed, drying and filtration of SF6, removing hazardous moisture and contaminants
• Bipolar single-acting compressor with international advanced compression technique which can compress SF6 to liquid and storage it into tank directly.
• Refilling SF6 gas into electric equipment, realize the recovery of SF6 gas, save the resources and maintenance cost.
• Storage system can be customized with various capacity as per user’s request.
