SF6 gas Mixtures products

Sulfur hexafluoride (SF 6) is a relatively nontoxic gas used in a number of applications for its inert qualities. The dielectric and other physical and chemical properties related to its lack of reactivity have led to the extensive use of SF 6 as an insulating medium in switching equipment (e.g., circuit breakers) by electric utilities. While SF 6

Overview

The three-phase equilibria of hydrate (H), liquid water (LW), and vapor (V) for the binary SF6 + water mixture and for the ternary N2 + SF6 + water mixtures with various SF6 vapor compositions (10, 30, 50, and 70%) were experimentally measured to determine the stability regions and formation conditions of pure and mixed hydrates.

As a pioneer in SF 6 gas handling with over 50 years of experience, we were able to combine tradition with the requirements of new gas mixtures. We are proud to be the first company to develop a complete product line for gas handling and maintenance of alternative gases. The handling of alternatives to SF6 comes with its own set of challenges.

DILO Products for Alternative Gases. DILO has developed a complete line of alternative gas handling and measuring devices for 3M TM Novec 4710 or 3M TM Novec 5110 gases. Our C4 and C5 product lines offer everything you need, from measuring devices to gas service carts, to handle these alternative gases.

Alternative gases as SF 6 substitute Focus on the environment. SF 6 is an excellent quenching and insulating gas which has been used in the energy sector worldwide for more than 50 years. The energy related development in the high and extra high voltage range would have been impossible without the use of SF 6 with its excellent dielectric stability and good electric arc quenching properties.

At normal temperature, the gas is stable, and does not react with its environment. In contact with the parts where electric currents circulate, the gas is heated to temperatures of around four hundred degrees SF6 gives the following decomposition products: Thionyl fluoride SOF2. Sulfur fluoride SO2F2.

SF6 Gas Recovery: Although SF6 is an excellent arc quenching and insulting gas for medium and high voltage switchgear, it has a very high global warming potential. SF6 gas should not be released into the environment. DILO offers you professional service carts for the recovery and reuse of SF6.

N2 / SF6 gas mixtures (5 - 10 % by volume of SF6) are employed to refine pure Aluminum or its alloys at melt temperatures in the range 650 - 750 &C. SF6 is a source of fluorine atoms reacting in the melt and removing inclusions of H2, oxides, particles and other casting impurity.

The new generation of the SF6-Multi-Analyser allows to determine the three major quality parameters (SF6 concentration, humidity and quantity of decomposition products) in one single operation. As a result, service specialists can determine on site whether the gas still complies with the IEC Standard 60480 (SF6 reuse) or whether it needs purification. Integrated batteries have been used as the
