Custom pressure relief solutions for lithium-ion batteries and BESS

Innovative pressure relief protection

Activation in <5 milliseconds and accurate venting at low pressures support rapid relief of heat and gas for a safer battery design. Holderless discs and vents with integrated frames reduce the number components for simple venting through ducting or direct to atmosphere.

Suitable for harsh conditions

Our robust disc designs have passed battery fire and puncture tests, and provide a leak-tight seal until activation. Our domed vents can withstand adverse weather conditions and are not affected by ice or snow. You can be confident of reliable performance in real-world conditions.

Collaborative engineering services

Our engineering team will work directly with you to design a custom solution that fits within your specifications. Our engineers can provide guidance on industry codes and standards so you can be confident you are using the best solution for your battery or enclosure.
