Deltae by Zelup: the revolutionary nozzle
The Deltae (abbreviation of “air water nozzle fire extinguishing device” in French) revolutionizes fire extinguishing systems with a unique process: two-phase misting flow. The firefighters who took part in the tests are unanimous: this new nozzle is safer, more effective and more ecological.
This product developed by Zelup produces and propels fine water droplets through a very high-speed air stream.
The process significantly reduces the flow rate, thus consuming 6 to 8 times less water than a traditional nozzle. With this powerful and ecological two-phase system, each drop of water plays its role and takes action on the fire system.
How does this (patented) two-phase system work
Pump
Compressor
Water (6-12 bars)
Air (6 bars)
Specific nozzle
Two-phase fogs (4 types)
Two-phase fogging is a fog obtained by a hydropneumatics water fragmentation process. The water droplets (liquid phase) are very finely divided by the expansion of air (gas phase). The fine droplets are then propelled in a gas stream at very high speed, allowing them to be carried to the heart of the fire.
