Long service life

Since its launch in 2004, the range has proved so robust and reliable in operation that the company offers a 3-year warranty as standard on Opti-Gard discs supplied after 1st January 2011.

Customers are able to more precisely calculate how long their discs will last in service and to better plan maintenance schedules.

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 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+. Elfab says that with 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.
