Drago-ISI Inc.
Drago-ISI Inc. (Drago Engineering and Fire Safety) specializes in the design and marketing of innovative solutions for fire control and water conservation. The Drago simplicity, efficiency and capability to flow to a maximum of 785Us gpm (2973 L/Min with a projection/distance exceeding 200 feet (60 meter).
The Drago uses our constant spray technology unlike any other fan cannon on the market. The unique center nozzle (Spider) design provides a smooth performance curve with optimal water flow and droplet quality settings compared to all other fan technologies.
It’s versatility to effectively stream a mixture of water / air / water + firefighting agent (foam or even encapsulating agents) at a great distance, in order to effectively carry out various maneuvers aimed at extinguishing the fire, cooling the surrounding air, slowing down the progression of the fire or the dispersal of smoke and toxic fumes.
The technology behind the Drago Spider.
One strategy for using water with improved efficiency and speeding up fire extinguishing for a given water flow rate would be to divide the flow into a large number of fine droplets distributed over a large area of the flaming mass. When the water is broken into small particles, it absorbs heat and converts into steam more rapidly because more of the waters surface is exposed to the heat in order to promote rapid evaporation.
Spraying water on a burning material is a common way to lower the temperature of the flaming mass to extinguish the fire. Directing straight streams of water at the base of a fire is not a very effective way of fighting the fire. One indication of this, is the large volume of water surrounding a site after fighting a fire. causing additional damage to the remaining structure and large firewater contaminate runoff into the environment and water treatment facility.
Indeed, one of the most useful properties of water for extinguishing a fire is its great capacity for absorbing heat. In particular, thanks to its unrivaled latent heat of evaporation. Therefore, water that does not evaporate is not used efficiently, besides being a source of collateral damage.
