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

We can reduce the maximum loss!!

Explosive proof pressure relief louver/shutter, Explosion safety louver for All type Container enclosure，all type energy/power container equipment


Ventilation Heat dissipation	Smooth circulation of internal & external airflow	Balance the pressure in & outside of equipment	Waterproof dustproof

Product working principle

When an accident occurs inside an energy container, resulting in open flames and leakage of flammable gases

With the leakage of combustible gases, the fire is becoming increasingly uncontrollable, the temperature inside the energy container continues to rise, and the thick smoke and expansion pressure increase, posing a risk of packaging occurring at any time

Equipped with our pressure relief shutterrs, they will automatically open according to the emergency situation you have set. Through the exhaust fan inside the structure, the combustible gases and thick smoke inside the energy container will be quickly expelled from the equipment. And it can reduce temperature and expansion pressure, avoiding the occurrence of equipment explosions
