Elfab’s Opti-Gard™ achieves another industry-first

Pressure management specialist Elfab (www.elfab.com) has tested its Opti-Gard™ range of rupture discs to over 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 1st January 2011.

Opti-Gard™’s improved service life and three-year warranty now allow customers to more precisely calculate how long their discs will last in service and to better plan their maintenance schedules following product installation.

Opti-Gard™’s three per cent 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 per cent.

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 three per cent across a wide range of burst pressures and a 95 per cent operating ratio, Opti-Gard™ offers the highest performance characteristics available for liquid, gas or vapour applications.
