Best high performance reverse acting rupture disc for use with Duplex Holders
Opti-Gard™ High Strength Magnet is a technically advanced reverse acting rupture disc solution specifically designed for use in applications where Duplex Holders are required. The Opti-Gard High Strength Magnet (OPM) is available across a wide range of sizes, materials, burst pressures and process conditions. OPM has been specifically designed for use with duplex holders available in 22cr and 25cr.
Opti-Gard High Strength Magnet 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 High Strength Magnet is a solid metal bursting disc with smooth surface finish, a non-fragmenting design and an optional add-on of a 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 OPM for use in applications operating up to 140°c. Withstanding full vacuum and high levels of back pressure without the need of an additional vacuum support ensures maximum free flow area on burst.
Accurate signalling with unique non-invasive detection system
Opti-Gard is installed into Elfab’s reverse-acting, raised face rupture disc holders and fitted with a high strength magnet as standard to allow for use of Elfab’s unique, reusable, non-invasive burst detection system Flo-Tel™+. OPM is fitted with a strenuous magnet specifically designed for use with duplex holders to give accurate signalling with Elfab’s unique detection system Flo-Tel; which is a cost saving and reusable method. 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. While Elfab’s rupture disc holders are available in a wide range of materials, the OPM design is specifically made for 22cr and 25cr Duplex.
