Those outdoors energy/power equipments are running normally every days

 

Regardless of the type of new energy equipment, various components are installed inside to operate, and each component requires safe conditions (appropriate temperature inside the cabinet) to function properly

 

 

If an accidental open flame occurs inside the BESS cabinet, it may leaks various possible flammable gases such as hydrogen or methane, the fire will intensify

 

As the combustible gas fire becomes increasingly uncontrollable, the internal temperature keeps rising, the pressure keeps pushing outwards, and finally becomes an uncontrollable explosion scene. The fire will affect dozens of battery cabinets around it, and the losses are incalculable

Product operation principle

 

Situation 1

 

Electric open pressure valve by sensor

HX-FBF-140B is a sensor operative valve, it can be associated with combustible gas monitoring. When the battery in the cabinet leaks combustion supporting gas, the explosion-proof valve will automatically open, attracting external air to dilute and flame retardant other components

 

Then

Electric pressure relief valve with fan

The HX-FBF-140C or D types will automatically turn on, the fan will start, and the peripheral air will be drawn in through the inlet of the B model, quickly exhausting the combustible gas and high temperature inside the cabinet, achieving the effect of rapid pressure relief, cooling, ventilation, and preventing explosions caused by excessive pressure

 

 

Situation 2- A model special treatment

Accidents cannot be predicted. If an accident inside the cabinet has caused sensor failure, short circuit, and the BCD types pressure relief valve to fail to open as expected, the open flame inside the cabinet will continue, and the temperature will continue to rise. The internal pressure will continue to expand outward, and the cabinet will face the result of explosion

 

Mechanical pressure relief valve

There is the ultimate guarantee of the A-type pressure relief valve. As the pressure inside the cabinet continues to rise and reaches the critical point where the A-type pressure pushes open, the A-type valve will mechanically open the valve through pressure, and the internal heat and thick smoke will be instantly discharged from the equipment, preventing a dangerous explosion.
