SF6 Gas Systems — GTRU

Overview

GTRU gas treatment & recovery units recover, purify and refill the SF6 gas with a high degree of safety and reliability and incorporate automated drive and control technology. Select Capacity: 1000m3/h. The units dry, filter and liquefy SF6 gas to refill internal tanks and external SF6 and enable liquefaction and storage in external tanks. The equipment is equipped with a display for monitoring vacuum and pressure levels and a highly efficient SF6 moisture and particulate filtration system while supporting air evacuation and moisture removal before refilling. Guaranteed treatment results: - Water: 25 ppmw - Mineral oil: <10 ppmw - Acid HF: 1 ppmw - SF6 Content (IEC New Gas): 99,55 vol. % - SF6 Content (IEC Used Gas): ca. 97,00 vol. % - Air Content (IEC New Gas): 1 vol % - Air Content (IEC Used Gas): < 3 vol % < 30 vol % - CF4 Content (IEC New Gas): 2400 ppmw - CF4 Content (IEC Used Gas): < 3 vol % < 5 vol % Designed for maintenance and regular servicing of SF6 switchgears, circuit breakers and gas compartments, the GTRU units are engineered for maintaining medium-sized breakers and GIS systems and can substantially improve equipment lifetime and performance while helping to save money. The systems enable recovery, purification and refill of SF6 gas and permit liquefaction and storage for refilling operations. They also offer the ability to recover and refill one gas compartment while evacuating another simultaneously, facilitate gas transfer and retrieval between external cylinders, and allow refilling from an independent gas cylinder and reservoir.
