Reliably Solved

The search for the right fire protection solution can be a maze, especially when it comes to highly specific use cases. Niche special hazards like lithium-ion battery storage and tunnel protection often require a tailored approach that standard solutions simply can’t provide. That’s where our consultative process can help. With Reliable, you’re not just buying a product, you’re securing a partner who understands the intricacies of your requirements, and will recommend tailored solutions best suited to your needs.

Lithium-Ion Battery Storage 

The LB11 HSW In-rack Sprinkler is a true game changer for safeguarding your storage. It’s the first of its kind to be rigorously tested and effectively proven to protect against the unique fire risks posed by the storage of lithium-ion batteries. Plus, it’s also the only horizontal sidewall sprinkler that is UL listed for protection of storage in racks, increasing flexibility in the configuration of your storage space. 

Watch for yourself as our team puts the LB11 HSW In-rack Sprinkler to the test. We set fire to lithium-ion batteries within a warehouse, where they were being stored in racks.

Fluorine-Free Foam 

In a world where environmental responsibility is critical, our collaboration with Solberg brings you SOLBERG® RE-HEALING® foam concentrates as the innovative answer for eco-conscious firefighting. Commonly used in high-risk environments like airplane hangars, these foam solutions provide rapid and reliable fire control, safeguarding valuable assets.

SOLBERG RF3 fluorine-free foam concentrate has proven performance for flame knockdown, fire control, and extinguishing time on hydrocarbon fuels. RF3 is UL Listed with bladder tanks, proportioners, and Reliable fire sprinklers. With matching sprinkler system application rates to AFFF, RF3 is the right choice as an environmentally responsible alternative for protecting hydrocarbon hazards. Reliable offers a full complement of fire sprinklers and valves for use in foam systems, so you can source your entire system directly from us.

Deluge Systems for Tunnels

Fire can escalate quickly in vehicle tunnels, due to the enclosed nature of the space, and the likely fuel sources. Deluge systems are the ultimate defense for this use case. Deluge systems consist of water supply, a valve, a system of piping and nozzles that are open to atmosphere, and a means of detection and actuation. When the deluge valve is activated, water flows through all nozzles controlled by the valve. Unlike automatic sprinkler systems, where water flows only through individual sprinklers that have activated close to the heat source, deluge systems are designed to “surround and drown” an entire zone to prevent the spread of fire in hazardous environments.

The Reliable® TNL280 pendent nozzle has been specifically designed to provide an extended coverage nozzle suitable for use in vehicle tunnels. Learn more about the nozzle in our case study, or in the video below.
