Surface mounted explosion vent BESS.EGV

stainless steel

Product overview
The REMBE® explosion vent BESS.EGV provides dedicated protection for Battery Energy Storage Systems (BESS). It is offered in multiple geometries with customisable burst pressures to suit various BESS designs.

Application
BESS.EGV is intended primarily for roof-mounted installation on BESS enclosures. The standard burst pressure is 0.1 bar at 22 °C, but it can be configured down to 0.025 bar for sensitive designs.

Advantages

• High venting capacity with full-bore opening thanks to low surface weight.
• Enhanced stability and rapid opening via integrated bionic structure.
• Wide range of EGV geometries for optimal adaptation to different BESS layouts.
• Quick, torque-independent installation; no additional counter frame required.
• Space-saving design with integrated gasket and frame.

Mechanism
During a deflagration, the vent opens at predefined breaking points, releasing pressure from the BESS to the surrounding environment and protecting the enclosure.
