However, the newer technology of water mist
systems offers better cooling and suppression of fire.
In the Vortex system, the nitrogen and water mist
function as complementary extinguishing agents.
Unlike many chemical extinguishing gases, FOGTEC water mist
systems neither destroy the ozone layer nor do they contribute to the greenhouse effect.
systems create a fine mist of water droplets, allowing the use of smaller quantities of water than conventional sprinkler systems.
In one dramatic and immediate measure, airplanes were sent up to spray water mist

The company entered the deal via its subsidiary, Water Mist
Engineering AS, which recently focused on offering nitrogen systems including oil free compressors.
Thinking outside the realm of traditional water mist
methods that have been based on water being mechanically sheared by injecting it onto deflectors, Victaulic researched different hardware concepts for fluid atomization with parallel gas flow.
In addition, the existing fire protection system will be replaced with a water mist

The Argocat will allow firefighters to drive almost directly into the blaze, using its fogging systems to spray a water mist
into fogging systems - high pressure water mist
jets that use a small amount of water to extinguish large grass fires.
RapidScan devices use Sonatest's Wheel Probes which have a rubber tyre acoustically matched to water to give low loss coupling into the test part without the need for gel or Large quantities of water and a fine water mist
is normally all that is needed for coupling to most surfaces.
26 gallon per minute per nozzle) efficiently cleans process fabrics without chemical additives; 2) no contaminated water mist
is expelled into the process area; 3) belt cleaning and drying is accomplished simultaneously; 4) contamination is collected and delivered to a save-all pan with a vacuum pick-up system that does not require an auxiliary vacuum pump or water separator system, and automatic nozzle, head cleaning and system maintenance is accomplished without interrupting continuous production.
