Best high performance characteristics for Liquid, Gas or Vapour applications across a wide range of burst pressures
Opti-Gard™ is a technically advanced reverse acting rupture disc solution to suit a wide range of customer applications and demanding process conditions. The Opti-Gard rupture disc acts as a single disc solution across a complete line of sizes, materials, burst pressures and process conditions.
Opti-Gard offers a unique range of benefits
Peripherally scored on the vent-side for accurate burst control, Opti-Gard benefits from a unique 3% tolerance with a 95%* operating to burst pressure ratio. With these industry-leading technical characteristics Opti-Gard can reduce stock holdings by as much as 65%! This offers significant cost savings as well as a reduced inventory and installation variance, while not affecting quality.
Full vacuum capability
Opti-Gard is a solid metal bursting disc with smooth surface finish, a non-fragmenting design and an optional process side fluoropolymer liner. Available in Stainless Steel and Hastelloy, as well as more exotic materials like tantalum, monel and Inconel, Elfab can manufacture the Opti-Gard range to be used even in the harshest of operating conditions while maintaining corrosion resistance. Withstanding full vacuum and high levels of back pressure without the need of an additional vacuum support ensures maximum free flow area on burst.
Cuttings costs on rewiring
Opti-Gard is installed into Elfab’s reverse-acting, raised face rupture disc holder and fitted with a magnet as standard to allow for use of Elfab’s unique, reusable, non-invasive burst detection system Flo-Tel™+. As the only ATEX, IECEx or XD approved detection system on the market, Flo-Tel has been offering significant cost savings to customers for almost 20 years. Elfab’s rupture disc holders are available in a wide range of materials and can be manufactured to fit a multitude of industry standard flange specifications.
