Custom pressure relief solutions for lithium-ion batteries and BESS

Innovative pressure relief protection

Dual-Gard disc in standard configuration

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

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.
