Gorilla PKW Dry-Chemical Vessel

Any industrial related 3-Dimensional fire requires forethought, tactical leverage, and adequate resources to sustain an overwhelming assault.

The Gorilla™ 500 LB PKW Dry-Chemical Pressure Vessel is designed as a three-dimensional fire response tool with about 30 lb (13.6 Kg) per second powder discharge capability.  The pressure vessel is designed per ASME specifications.  Powered by a common 400 cubic foot (11.3 m³) nitrogen cylinder mounted on the skid, the GORILLA can apply PKW dry chemical using Hydro-Chem™ Ranger nozzles, Hydro-Chem™ Handgun nozzles (single, double, or even triple), or Dual Agent Foam Chambers from Williams Fire & Hazard Control.  This vessel will drive up to 600 feet (17 m) of dry powder hose depending on hose size, number of lays, and the cylinder capacity.

PKW™ Dry Chemical from Williams Fire & Hazard Control is a highly specialized siliconized Purple-K that is one of the most effective dry chemicals used to extinguish flammable and/or combustible liquid fires.  PKW is a potassium bicarbonate-based dry chemical containing chemical additives. The agent is free-flowing, water-repellant, non-abrasive and, when used as a fire extinguishing agent, produces no toxic effects.

Its distinctive, deep purple color provides the firefighter with the ability to stay on target when the dry chemical is projected onto the fire within the water/foam solution stream. The result, when combined with Hydro-Chem™ Technology, is the ability to achieve a quicker “knockdown”, while using less chemical to complete the job.

The vessel has a standard 2.5” (M)NST discharge connection with an intuitive control panel.  It can be easily transported by forklift or crane with built-in fork holes and lifting frame/eyes.  It can also be secured onto a truck, trailer or other platform with its mounting holes in the lower skid.  Once the job is done, the vessel venting feature relieves pressure from the vessel safely and with ease.  The venting nitrogen can be used to “pre-clean” the hoses followed by switching to pure nitrogen for thorough cleaning of the hoses.  For sustained attacks, the vessel can be refilled, and the nitrogen cylinder replaced, in a matter of minutes.

This product is a great resource for supplying hand line and trailer-mounted monitor attacks on events involving running or falling fuels and pressure fires.
