Reversing rupture disc with highest performance

Opti-Gard is a modern reverse rupture disc for highest demands. With an operating/burst pressure ratio of 95 % and a performance tolerance of 3 %, Elfab’s Opti-Gard is available as a single-disc solution in numerous sizes and available for a wide range of bursting pressures. In doing so, the Opti-Gard offers the ability to reduce your inventory by up to 65%.

Reverse Rupture Disk for Ultra-Low Pressure Applications

These composite reverse rupture discs are ideal for relieving pressures at both negative and positive pressures. Due to its modular design, it can be adapted to a wide range of non-standard specifications and applications

Rupture disc With preload

Safe-Gard is a modern rupture disc with preload. A cross-shaped precision notch on the vent side ensures accurate fracture behavior. The domed disc consists of a single diaphragm and is suitable for liquids and gases with an operating/burst pressure ratio of 90%. Ideal for a wide range of burst pressures and sizes, Safe-Gard combines the versatility of conventional metal discs with the performance advantages of indentation technology.

Rupture disc made of graphite

Universal Arma-Gard is an advanced graphite bursting disc that can be mounted between flanges without a retainer. The unique design solves the problem of conventional graphite bursting discs being compromised due to poor storage, handling or installation. This is achieved by a steel reinforcement ring that protects the graphite bursting disc element while allowing for tight clamping and proper sealing. Unlike conventional monobloc designs, Universal Arma-Gard eliminates the possibility of sidewall breakage.

Rupture disc – Unique on the market, also available as high pressure version (HPSR)

The Oseco Safety Cartridge™combines the traditional three components of a rupture disc system into one hermetically sealed component. It can be easily installed in critical applications. At the same time, maintenance effort, costs and time requirements are reduced. The Oseco Safety Cartridge™ system guarantees absolute leak protection by completely eliminating the need to seal the rupture disc in a holder. These high-performance, one-piece units are shipped from the factory leak-tight and install in seconds. No other rupture disc solution is as effective and easy to install. No occurring tensions or forces. No problems due to torque applied too high.

Sanitary pressure relief

Pure-Gard is an innovative, sanitary pressure relief solution designed specifically for applications where cleanliness is a top priority. The new disc design offers a cleanable, robust solution that will help you deal with the challenges of complex manufacturing environments – including pharmaceutical, biopharmaceutical and food processing. Pure-Gard offers a solution that is completely independent of the gasket – gaskets can be replaced regularly without having to replace the pane. This innovative design feature ensures that Pure-Gard’s useful life exceeds that of traditional sanitary pressure relief solutions. The rupture disc remains protected thanks to the one-piece design, minimizing the risk of damage during installation. Due to Pure-Gard’s stable structure, ventilation-side piping loads have no effect on its performance. Also available as a low-pressure version, Pure Gard Solo.

Flo-Tel and Test-Tel + Holder

The Flo-Tel system for monitoring is simply, non-invasively, screwed into the holder from the outside. Flo-Tel can be reused indefinitely. Can be used without problems even in critical environments due to ATEX approval. Flo-Tel is an excellent solution for determining when a rupture disc will respond under severe operating conditions. After bursting, only the bursting element must be replaced. The high cost of a Rewiring not required. In interaction with Radio-Tel™ the process temperature can also be monitored with Flo-Tel via a built-in thermistor.
The mobile test device Test-Tel can also be used to conveniently check any rupture disc for defects in a matter of seconds. All holders are prepared for the use of Flo-Tel or Test-Tel.
