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