SF6 Gas Test, Handling & Purifying Equipment
Gas analyzers, recovery units, purification systems, and handling tools for SF₆-insulated switchgear and high-voltage equipment.
SF6 is one of the most potent greenhouse gases known, with a global warming potential nearly 25,000 times that of CO2 and an atmospheric lifetime of up to 50,000 years. At the same time, it remains the dielectric of choice for high-voltage circuit breakers, gas-insulated switchgear, and transmission infrastructure. Properly managing SF6 is no longer optional. It is an operational, environmental, and regulatory requirement. ProgUSA offers a full selection of SF6 analysis, recovery, purification, and handling equipment from RH Systems, Enervac, and Synecom, along with support, training, and service throughout the United StatesProgUSA offers a full selection of SF6 analysis, recovery, purification, and handling equipment from RH Systems, Enervac, and Synecom, along with support, training, and service throughout the United States.
