BESS.Q.Vent
Flameless venting for indoor BESS and sensitive environments.

As the pioneer of flameless venting technology, REMBE® has engineered the first flameless vent for battery energy storage systems. BESS.Q.Vent extinguishes the flame and minimises external temperature and pressure effects. It can protect both indoor and outdoor BESS and can be installed on BESS roofs or side-walls.
Application
BESS.Q.Vent is ideal for protecting BESS located indoors, or outdoor BESS in sensitive environments where flame exit and pressure effects are not acceptable.
Advantages
- Flame absorber.
- Reduced safety area.
- Wall or roof installation at BESS.
- Uniquely slim profile: Blends in with the container wall, allows containers to be stacked.
- Maintenance-free.
- Reduction of external explosion pressures.
- Suitable for indoor installation of the BESS.
Mechanism
The special stainless steel mesh filter developed by REMBE® cools the hot flame gases extremely efficiently. This leads to flame extinguishment and further cooling, such that external temperatures and also external pressures are significantly reduced.
