GORE® Protective Vents for Sealed Battery Enclosures
Our advanced venting technology shields sensitive equipment from moisture ingress, pressure fluctuations and long-term degradations where typical sealed enclosures fall short.
Safeguard Your System for Longer Battery Life
Sealed battery enclosures are designed to withstand harsh outdoor conditions, but thermal changes due to operational and environmental stressors can create pressure imbalances, even in the most robust systems. Without a pressure equalization solution, the enclosure seals can fail causing the sensitive electronics inside to become vulnerable to increased condensation and potential corrosion from moisture ingress. Ultimately, battery life and system performance could be compromised.
Don't leave your battery energy storage system (BESS) vulnerable to condensation and potential corrosion.
GORE Protective Vents can help:
Plus, our products are:
- Easy to Integrate
- Backed by Decades of Experiences
- Supported by Deep Consultative Technical Expertise
Applications that may benefit:
Battery Energy Storage Systems (BESS): Stationary battery energy storage systems benefit from protective vents to minimize harmful pressure differentials and protect against environmental perils.
Industrial Equipment: Heavy machinery and industrial tools rely on protective vents to ensure their battery systems can withstand harsh conditions and maintain consistent performance.
Telecommunications: Backup power systems for telecommunications infrastructure use protective vents to ensure batteries remain operational during power outages and environmental challenges.
Various Product Configurations to Fit Variety of BESS Enclosure Designs:
Screw-In Vents
The Screw-In Series offers a variety of performance options that durably withstand mechanical stresses and rugged environments. They all provide oleophobic membranes and are hydrolytically-stable, UV- and temperature-resistant.
Snap-In Vents
The Snap-In Series delivers fast reliable installation and durable protection for enclosure volumes of all sizes, from less than 0.5 liters up to 30 liters. Ideal for high-throughput or manual production, the Snap-In Series offers multiple performance options.
Adhesive Vents
Low-profile Adhesive Vents are available in both standard and custom designs, offering the most flexible options: for manual or automated installation, for interior or exterior mounting on enclosures, and for adhesion to rough or smooth substrates.
