OsecoElfab
About us
OsecoElfab is a leading global provider of pressure relief and explosion protection solutions, headquartered in the USA and UK. Our purpose is ‘Protecting life. Solutions for a safer, cleaner world.’
Following this purpose, we design and manufacture rupture discs, explosion vents and associated burst detection systems to protect people, plant and the environment.
Our services include highly specialised engineering and design consultation, product training seminars, site surveys and a stock consolidation programme.
Serving a global customer base, we have two manufacturing facilities: one in Broken Arrow, Oklahoma (USA) and one in North Shields, UK. These are supported by six regional sales offices and over sixty approved representatives worldwide.
Alongside the chemical process industry, key sectors include pharmaceutical and biopharmaceutical, power transmission and distribution, bulk handling, gas generation and handling, cryogenics, medical, aerospace and energy.
OsecoElfab is part of the Halma Group, a FTSE 100 company with over 50 subsidiaries worldwide.
Products
Opti-Gard rupture disc
Opti-Gard is a high-performance reverse acting rupture disc. With a high operating ratio of up to 95% combined with an industry-leading burst tolerance of +/-3%, it enables exceptionally high performance that supports process safety and efficiency. Opti-Gard features a smooth surface finish and can be supplied with an optional fluoropolymer liner on the process and/or vacuum side. It withstands full vacuum and high levels of back pressure without additional vacuum support to ensure the maximum free-flow area on burst. We supply Opti-Gard as standard with a magnet for our non-invasive burst detection system, Flo-Tel. Flo-Tel offers a practical, reusable solution for detecting when a rupture disc has functioned. The sensor is non-invasive to the process and is therefore unaffected by downstream pressure fluctuations or corrosion. After an overpressure event, the sensor does not need replacing, which eliminates the need for expensive re-wiring costs and maintenance planning. Our dual-certified dual-certified Exd/EXia/b system Flo-Tel XD offers the same non-invasive burst detection for hazardous and explosive environments.
Opti-Gard SoLo - Low-pressure rupture disc
Opti-Gard SoLo is an innovative, low pressure rupture disc that works reliably even in demanding process conditions. The unique, patented geometry of this reverse-acting rupture disc enables accurate bursting in low pressure applications. The solid metal bursting disc operates accurately from pressures as low as 2 psig. Install Opti-Gard SoLo in our reverse-acting rupture disc holder. We fit the disc with a magnet as standard so you can use it with Elfab’s unique, reusable, non-invasive burst detection system Flo-Tel.
Flo-Tel - Non-invasive burst sensor
Flo-Tel is a practical, reusable burst detection solution for indicating when a rupture disc has activated. Operating on a simple reed switch and magnet technology, the Flo-Tel burst sensor fits into a holder with a magnet on the rupture disc. When the rupture disc bursts, the magnet arcs away from the sensor, giving an open circuit signal. Flo-Tel is non-invasive to the process and is therefore unaffected by downstream pressure fluctuations or corrosion. This feature also eliminates leak paths and the risk of false alarms associated with traditional membrane-type burst detection systems. After rupturing, the disc is the only element that needs replacing, which eliminates the need for expensive re-wiring costs and maintenance planning. Available with a 2m, 5m or 10m cable, Flo-Tel is Suitable for process temperatures up to 300°C and offers a fail-safe detection system. Flo-Tel is ATEX approved to II 1G Ex ia IIC Ga and II 1D Ex ia IIIC Da IP66. It carries the EC-Type Examination Certificate ITS03 ATEX 21698X. Please note that it must be connected to an intrinsically safe supply.
