Dual-Gard is our unique design solution for the challenges of pressure relief and explosion protection in new energy storage technologies. Part of our OE Lion range of specialty products for li-ion batteries, the dual device integrates a breathing membrane with a metal rupture disc or explosion vent. This enables breathing and venting from a single location. The result is a simpler, cleaner lithium-ion battery and enclosure design that is quicker to assemble and easier to integrate.
The additional breathing function allows air and other gases to move in and out of the enclosure. This prevents a build-up of gas and pressure, and guards against any swelling or contracting of the enclosure. In an emergency venting situation, the metal disc or vent will operate as usual to relieve overpressure quickly and safely.
The patent pending design is fully customizable and can be integrated into our range of metal discs and explosion vents. Dual-Gard is ideal for any application that requires ongoing pressure equalization alongside rapid overpressure relief.
The breathing membrane can be integrated into either a rupture disc or an explosion vent panel. It is ideal for energy storage applications, such as BESS units, or the li-ion batteries used in e-Mobility, where both pressure equalization and explosion protection are required.
