Further improvements to technically advanced rupture disc range

Elfab has further developed it’s Opti-Gard rupture disc making it the only reverse-acting disc on the market to benefit from a 3% tolerance and an improved 97% operating ratio.  

The financial and operational benefits of this design to customers are extensive. The 3% tolerance combined with an operating ratio of 97% increases the service life of the rupture disc and can reduce stock holdings by up to 65%. Combining state-of-the-art equipment with over 75 years manufacturing experience, Elfab are the first rupture disc supplier to increase an operating ratio from 95% to 97% while maintaining its unique 3% tolerance.  

The Opti-Gard system comprises a reverse-acting rupture disc, a single design holder suitable for a wide range of flange specifications and industry leading, non-invasive ATEX-approved burst detector Flo-Tel.

Integral Flo-Tel is Opti-Gard’s non-invasive ATEX approved detection device. Unlike traditional membrane detectors, Flo-Tel is reusable and so only requires a one off installation. Since it’s isolated from downstream pressure fluctuations or aggressive media, it will not cause unnecessary downtime though spurious failure indication
