Above: Test 5 - Immediately following activation of the Reliable TNL280 Nozzles
Electric Vehicle Fire Test:
Test 5 in the series included three Model 3 Tesla electric vehicles in the configuration below as well as an ICE vehicle located upstream of the ignition car. A small pool fire of diesel fuel located directly under the battery casing was the ignition source. The pool fire was small but concentrated to ensure only localized heating of the battery.
SUMMARY The Reliable TNL280 Tunnel Nozzle has demonstrated its efficacy in controlling fires in various challenging scenarios. The comprehensive testing conducted at the Applus+ facility in Asturias, Spain, has provided valuable data for tunnel designers and fire safety professionals. The nozzle’s performance in maintaining tenable conditions and controlling fires upon activation makes it a reliable choice for tunnel fire protection systems.
The testing objectives were successfully met,
providing valuable insights into the nozzle’s performance in real-world applications. The data obtained from the tests will aid tunnel designers in smoke control system design and ensure the safety of egressing occupants and firefighters. Overall, the Reliable TNL280 Tunnel Nozzle has
proven to be an effective solution for tunnel fire protection, capable of handling various fire scenarios and maintaining tenable conditions. The comprehensive testing and positive results highlight the nozzle’s reliability and efficacy in real-world applications.
