Elfab’s Opti-Gard achieves another industry-first
Pressure management specialist Elfab has tested its Opti-Gard range of rupture discs to more than one million life cycles. The new service life, over four times longer than previously achieved within the industry, is a significant improvement.
Two years ago Opti-Gard became the first rupture disc to be protected by a three-year warranty. Since its launch in 2004, the range has proved so robust and reliable in operation that Elfab offers a three-year warranty as standard on Opti-Gard discs supplied after 1 January 2011.
Opti-Gard’s improved service life and three-year warranty now allow customers to calculate more precisely how long their discs will last in service and to plan their maintenance schedules better following product installation.
Opti-Gard’s 3% performance tolerance has allowed the optimisation of process pressures for many of Elfab’s customers. Apart from lowering re-supply costs, this has reduced disc inventories by up to 65%.
The Opti-Gard system comprises a reverse-acting rupture disc, a single-design holder with multi-flange compatibility and a non-invasive, ATEX-approved burst detector, Flo-Tel+. Featuring an industry-leading tolerance of only 3% across a wide range of burst pressures and a 95% operating ratio, Opti-Gard offers the highest performance characteristics available for liquid, gas or vapour applications.
