APPLICATIONS

The greatest danger in a BESS is to have a thermal runaway due to a faulty battery. A single defective battery cell is enough to create a thermal runaway which can either result in a very severe uncontrolled fire or 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 “ventilate” the BESS sufficiently when a flammable gas is detected or during an explosion.

The DUAL-VENT precisely meets this need, with its ability to operate in both situations.

A. VENTING BY GAS DETECTION

(NFPA69)

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

(NFPA68)

In the event that a thermal runaway cannot be controlled and the process turns into an explosion, the DUAL-VENT, which is dynamically tested and has a certified explosion vent, will open due to the overpressure created by the explosion.

All panels in the Arc-vent range are compatible with Dual-vent.

The DUAL-VENT is an efficient solution to mitigate hazards and consequences of thermal runaway within the BESS.

It is the only product on the market which could meet both NFPA 68 and 69 standards. It is a very competitive and reasonable investment compared to inefficient alternative systems.
