Get PriceSafePlus uses SF6 (Sulfur hexafluoride) as an insulation and quenching medium. The SF6 is contained in a welded, stainless steel, sealed for life enclosure with an operating lifetime better than 30 years. The leakage rate is less than 0.1% per year! The switchgear is type tested according to ANSI/IEEE C37.20.3, C37.58, C37.54, and UL listed.
Get Price13/07/2017Failure to properly monitor and control moisture in heat treat furnaces (anodizing, annealing, hardening) risks poor metal quality and potential equipment failure. The presence of metallic particulates and combustion byproducts in these processes requires a sampling system with appropriate filtration to protect the dewpoint sensor and obtain accurate readings.
