Who we are ?

STIF is a global leader in manufacturing of fire and explosion protection solutions for Battery energy Storage Systems (BESS), headquartered in France.

Innovation, which is a strong part of the company’s DNA, has enabled the VIGILEX division to experience rapid growth in recent years for the EXPLOSION PROTECTION sector.

STIF constantly monitors potential new markets, which led to the conception, engineering, and design of products meant specifically to protect against fires and explosions in BESS.

To engage as closely as possible with BESS customers and provide them with a range of products designed for their unique requirements, STIF created a new division specifically focused on the BESS market called : VIGILEX ENERGY

In this catalog you will find solutions to effectively protect BESS containers from the risks of explosions and fires.
We also can customize products based on your system’s specific requirements.

BESS market :

In just a few years, BESS have become an unparalleled solution to the intermittency of most renewable energy sources such as wind and solar.

These battery systems (most often lithium-ion based) make it possible to supply electricity for several hours by acting as a relay even when renewable energy generation is not active.

Like any highly complex electric system, however, it is important to protect the assets and limit the risks of explosions and fires that are caused by occasional thermal runaway within the batteries.

This is where VIGILEX ENERGY comes in by offering you our expertise in:

  • The sizing and configuration of deflagration vents.
  • Understanding and conforming to the relevant safety standards in effect around the world.
  • Technical support, including the option of conducting joint studies, research & development, and testing to achieve the perfect solution for your system.
  • A wide range of solutions for your specific system design, including fully waterproof IP67 rated products
    and others that respond to the requirements of both NFPA 68 and NFPA 69 – detecting and releasing gasses or opening to release the pressure during an explosion.
  • We can support your local supply chain globally, with factories in France (Europe), China (Asia), and the USA (Americas).
