Dual-Gard is our unique design solution for the challenges of pressure relief and explosion protection in new eMobility and Battery Energy Storage (BESS) technologies.
Part of our OE Lion range of specialty products for lithium-ion batteries, the dual device integrates a breathing membrane with a metal rupture disc or explosion vent.
Breathing and Venting from a Single Location
The breathable membrane allows air and other gases to move in and out of the enclosure for ongoing pressure equalization. This prevents a build-up of gas and pressure, and guards against any swelling or contracting of the enclosure.
Dual-Gard can be integrated with a rupture disc or explosion vent to offer rapid, full-bore emergency venting. It 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.
Dual-Gard offers a unique solution for safer, cleaner energy storage in BESS units and efficient lithium battery design for electric and hybrid vehicles. Using Dual-Gard, you'll never need to compromise on lithium-ion battery safety, design or performance again.
Guard Against Propagation
Improve lithium-ion battery safety with an IP-rated membrane to equalize pressure to prevent batteries from swelling or contracting. The metal disc or vent activates within milliseconds for rapid, full-bore pressure relief.
Overcome Space Limitations
Both breathing and outgassing can be funneled though a single device, venting all gases from a common location. This improves your ability to control and disperse flammable vent gases.
Customize for Different Lithium-ion Battery Applications
The breathing area is scalable to fit different pressure equalization requirements. The number, size and shape of venting holes can increase or decrease the breathing area depending on the flow requirements of a particular li-ion battery enclosure.
Reduce Battery Inventory, Assembly and Integration Costs
Eliminating additional components means you have less inventory to manage and fewer components to assemble. This enables a less expensive battery enclosure, while the simple and clean battery design is quicker to assemble and easier to integrate.
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.
