Is a fire rated barrier required?

Flexible tubing is required to be mounted behind a fire rated barrier. Stainless Steel 316 rigid pipework can also be used for surface run applications where a fire rated barrier is not suitable.

How does the nozzle operate?

Each nozzle contains a frangible bulb that heats up in the event of a fire, this then bursts when a certain temperature is reached, activating the system and allows mist to exit the nozzle. We can change the bulb on request depending on the application. For example, if you require your sauna or an orangery to be fire protected, we can change the activation temperature of the bulb to ensure it operates effectively in any environment.
