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).

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.
