Buckeye N-2HP-10 Green Nozzle, 10 Pack

The Buckeye Green Nozzle (N-2HP) is the specialized long-throw solution for high-heat hazards within the Kitchen Mister ecosystem. While standard nozzles serve as the baseline for lower surfaces, the N-2HP utilizes a 2-flow point hydraulic rating to deliver a concentrated volume of agent from an elevated position. Engineered specifically for high-proximity mounting at 24 to 45 inches, this nozzle is the primary specified choice for single-vat fryer protection (20.25" x 24"), tilting skillets, and intensive lava rock charbroilers.

Constructed from premium chrome-plated brass, the N-2HP is built to withstand the extreme thermal signatures of high-BTU appliances without sacrificial degradation. It is instantly identifiable by its distinctive green color-coded band, ensuring safety technicians can verify the system's hydraulic calibration at a glance during mandatory audits. By projecting a targeted high-velocity spray, the N-2HP achieves immediate knockdown and initiates a deep saponification reaction, creating a robust foam blanket that prevents re-ignition.

The N-2HP must be installed by a licensed fire suppression technician in strict accordance with the Buckeye Kitchen Mister BFR design manual, NFPA 17A, and NFPA 96. The mounting height of 24 to 45 inches must be observed precisely. Nozzle placement must also conform to the specific Nozzle Aiming Point (NAP) chart in the Buckeye technical manual for each listed appliance. The N-2HP is specifically listed for single-vat fryers, tilting skillets, and lava rock charbroilers; it must not be substituted for surface hazards it is not listed for, as this can result in poor agent distribution and a UL 300 compliance failure.

Because the N-2HP consumes 2 flow points from the cylinder's total pressure budget, the technician must verify during system design that the sum of all nozzle flow points does not exceed the rated cylinder capacity. A blow-off cap must be installed on every N-2HP at all times. During each semi-annual inspection, technicians must verify the cap is present and intact and that the orifice is unobstructed by grease caking. Any nozzle showing signs of corrosion, heat distortion, or orifice restriction must be replaced with a new OEM N-2HP to maintain the system's UL listing.

Why is the 2-flow rating critical for high-proximity mounting?

At distances up to 45 inches, the extinguishing agent must overcome significant air turbulence and the appliance's thermal plume. The 2-flow rating provides the necessary mass-flow rate to ensure the high-velocity spray maintains its energy, reaching the oil surface with enough concentration to achieve saponification before the agent is deflected by the exhaust fan's suction.

Can the Green Nozzle be used for standard griddles?

While structurally capable, the N-2HP is specifically listed for fryers, skillets, and lava rock charbroilers. For standard griddles, Buckeye typically specifies the Blue (N-1HP) or Yellow (N-2LP) series depending on surface area. Using a high-proximity nozzle for a surface hazard it is not listed for can result in poor agent distribution and a UL 300 compliance failure.

What is the significance of the "Lava Rock" charbroiler listing?

Lava rock charbroilers generate intense radiant heat and deep-seated fires within the rock bed. The N-2HP's 2-flow hydraulic profile is calibrated to penetrate this heat layer, providing the high-volume quenching required to cool the lava rocks while simultaneously knocking down the surface grease fire.
