PYROSTOP™ 6 IEC 60376 DIELECTRIC GAS, NON TOXIC AND NON FLAMMABLE GOOD ELECTRICAL ARC SWITCHING CHARACTERISTICS COVER GAS IN MAGNESIUM FOUNDRIES AND AVOIDS THE INFLAMMATION OF MELTING MAGNESIUM BENEFITS • PYROSTOP IEC 60376 is filled in high voltage gas insulated switchgear (GIS), in particles accelerators and also in metallurgy industry (cover gas for magnesium). TM PERFORMANCE & RELIABILITY • Is a stable and inert gaz. It has no aggressive impact on the materials. Its dielectric strength is higher than the air, the nitrogen or the CO2. • It complies with IEC 60376 standard. Due to its high greenhouse warming potential, it is necessary to avoid all the emissions of this gas in the atmosphere. INVENTEC proposes you gas transfer or recovery units, as well as a complete offer in terms of recovery and recycling of the gaz. (Please refer to advises for use). USE CONDITIONS TM PYROSTOP IEC 60376 is a greenhouse gas. Using transfer equipment for this gas, will allow you to filter impurities and to dry the gas passing through the dehydrator. TM PYROSTOP IEC 60376 is a liquefied gas. Handling should be done by operators qualified, trained and certified to risks related to the use of the gas under pressure and to wear individual protection equipment. TM We advise you to read our user guide PYROSTOP . PHYSICOCHEMICAL DATA Analysis on the liquid phase as specified in IEC 60376 norm.
