Description
The Ranger Automatic Hydro-Chem Monitor Nozzle takes advantage of the effective range of an automatic monitor nozzle to deliver dry chemical along with water or a water/foam solution. Designed to extinguish three dimensional or pressure fed fires, the unique nozzle discharges dry chemical at approximately 20 lbs/sec (9 Kg/sec) through the center of the water/foam stream, resulting in a reach distance not possible with conventional dry chemical equipment.
All Ranger Monitor Nozzles feature constant pressure modulation. These nozzles can flow water or water/foam solution generated by various proportioning methods from 250 to 2,000 gpm (946 to 7,571 Lpm) depending on model number. The nozzle tip pressure is automatically maintained at a nominal 100 psi (6.9 bars) ± 10% to assure maximum effective reach of the water/foam solution over the flow range. The self-educting function is not available on these Hydro-Chem nozzles. Pressurized stream of dry chemical such as the siliconized PKW from Williams Fire & Hazard Control is discharged via the built-in 1.5” (F)NPT chemical port through the dry chemical tip on the nozzle. The dry chemical is carried by the water/foam steam to hit the target, overcoming the very limited reach distance of conventional dry chemical equipment. In typical applications, water/foam solution is first used to control the fire followed by dry chemical discharge to extinguish it.
