DOUBLE ACTION PRODUCT
The greatest danger in a BESS is to have a thermal runaway due to a faulty battery. A single faulty battery cell is enough to engender the thermal runaway which will result either in a very difficult to control fire or in an explosion.
Fire extinguishing systems typically installed in BESS are not sufficient to protect against the phenomenon of thermal runaway.
Several expert reports demonstrate this very well.
It is imperative to be able to “ventilate” the BESS well either when flammable gas is detected or during a possible explosion.
The DUAL-VENT meets exactly this need, with its ability to operate in these 2 situations.
A. VENTING BY GAS DETECTION
（NFPA 69）
One of the ways to reduce hazards due to thermal runaway is to detect gas escaping from defective batteries early in the process with the help of suitable gas detectors.
Our DUAL-VENT solution allows us to activate the opening of our vent following the detection of these gases.
Following this opening, the ventilation of flammable gases to the outside will considerably reduce the risk of fire and explosion.
After venting, the DUAL-VENT could reclosed automatically.
B. VENTING AFTER EXPLOSION
（NFPA 68）
In the event that the thermal runaway could not be controlled and the process goes to a real explosion, the DUAL-VENT which includes a real tested and certified explosion vent, will open following the pressure released by the explosion.
All panels in the Arc-vent range are compatible with Dual-vent.
The DUAL-VENT is definitely the solution to reduce the risks and consequences of the thermal runaway of the BESS.
It is the only product on the market to meet both NFPA 68 and 69 standards. It is a very reasonable and competitive investment compared to inefficient alternative systems.
And since the 2023 version of the 855 standard, it is mandatory to incorporate explosion vents on the BESS.
