Buckeye N-2LP Yellow Nozzle, 10 Pack

The Buckeye Yellow Nozzle (N-2LP) is the high-output workhorse of the Kitchen Mister fire suppression line. While 1-flow nozzles are the standard for small burners, the N-2LP Yellow Nozzle is specifically engineered for high-demand hazards such as six-burner range protection, extra-large griddles, and heavy-duty charbroilers. As a 2-flow point rated component, it delivers double the volume of extinguishing agent compared to standard nozzles, allowing it to blanket expansive cooking surfaces up to a 36" x 24" coverage area with a single discharge point.

Manufactured from chrome-plated brass to endure the high-vibration atmosphere of an industrial hood, the N-2LP is instantly identifiable by its distinctive yellow color-coded band. This visual cue allows contractors to verify at a glance that the hydraulic math of the system matches the appliance layout. By initiating a rapid saponification reaction, the N-2LP provides the heavy-duty knockdown power required for UL 300 and NFPA 17A compliance. The N-2LP-10 10-pack ensures your service fleet is equipped for high-capacity installations.

The N-2LP 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. Because the N-2LP 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. The manifold piping must also be sized correctly to deliver the necessary agent volume to a 2-flow tip without a significant drop in velocity.

Nozzle placement must conform to the specific Nozzle Aiming Point (NAP) for each protected appliance as defined in the Buckeye technical manual. A blow-off cap must be installed on every N-2LP to protect the discharge orifice from grease caking between service visits. During each semi-annual inspection, technicians must verify the cap is present and intact, confirm the orifice is unobstructed, and ensure the correct yellow nozzle is matched to the correct appliance zone. Any nozzle showing signs of corrosion or orifice restriction must be replaced with a new OEM N-2LP to maintain the system's UL listing.

Why would I use one N-2LP instead of two N-1HP nozzles?

Hydraulic efficiency and friction loss mitigation. While two 1-flow nozzles equal the volume of one 2-flow nozzle, the N-2LP allows for a simplified piping network with fewer junctions. This maintains a unified mist concentration over a large hazard, ensuring there are no dry spots in the foam blanket.

Does the N-2LP require different blow-off caps?

The N-2LP is compatible with standard Buckeye caps. However, because it manages a higher mass-flow rate, it is critical to use genuine OEM versions. A non-compliant cap might create too much back-pressure, potentially disrupting the 2-flow spray pattern at the exact moment of activation.

How does the 2-flow rating affect my cylinder capacity?

In a pre-engineered system, every nozzle draws from the cylinder's total pressure budget. The sum of all nozzle flow points in the system must not exceed the rated cylinder capacity. Using an N-2LP consumes two of these units, so technicians must verify that the manifold piping is sized correctly to deliver the necessary agent volume to a 2-flow tip without a significant drop in velocity.
