Both the portable Jet-X nozzle and the Hydro-X-5 unit manufactured by Bliss-Rockwood employ water power to dispense foam at rates ranging up to 7500 cubic feet per minute. The Hydro-X-5 can be installed permanently in high-hazard industrial and military areas, or it can be mounted on a skid, trailer or truck. Following development of the 18pound Jet-X nozzle by Rockwood engineer Bert Lundberg, in 1963, experiments were conducted at Holden, Mass., test site with the unit that became the Hydro-X-5.
