Buckeye N-1HP Blue Nozzle, 10 Pack

The Buckeye Blue Nozzle (N-1HP) is a high-performance, precision-engineered discharge component designed exclusively for the Buckeye Kitchen Mister fire suppression system. In the sophisticated architecture of a commercial kitchen, the nozzle is the definitive delivery point, the component responsible for converting a pressurized liquid agent into a life-saving mist. The N-1HP is a 1-flow point rated nozzle, acting as the industry standard for protecting high-heat cooking surfaces such as industrial ranges, griddles, and commercial ovens.

Manufactured from heavy-duty chrome-plated brass, the N-1HP is built to survive the brutal, grease-laden environment of a commercial exhaust hood. This 10-pack (P/N N-1HP-10) is a strategic inventory asset for service teams, ensuring a consistent supply of OEM hardware for large-scale installations and mandatory semi-annual maintenance. Utilizing the genuine Buckeye N-1HP ensures your facility maintains its UL 300 listing and discharge spray patterns remain consistent with factory-tested safety parameters.

Hydraulic Load Balancing

As a 1-flow point nozzle, the Blue Nozzle is a primary unit of measurement in system design, allowing engineers to calculate exactly how many nozzles a single tank can support. The 1-flow rating provides a uniform spray that achieves rapid flame knockdown without overwhelming the system's total pressure budget, ensuring every appliance on the line receives an equal concentration of agent during a discharge event.

The Saponification Reaction

When the potassium-carbonate agent is discharged through the N-1HP nozzle, it initiates saponification. The agent reacts with the free fatty acids found in hot cooking grease to form a thick, non-combustible soap foam blanket that excludes atmospheric oxygen to smother the flames and traps flammable vapors to prevent re-flash.

Laminar Mist Distribution

The internal geometry of the N-1HP is machined to produce a uniform spray pattern optimized for surface hazard suppression. If the droplets are too large they can cause splash-back of the hot oil; if too small they can be deflected by the fire's thermal plume. The N-1HP is calibrated to achieve a soft landing atomization, ensuring maximum chemical concentration on the hazard surface.

High-Visibility Field ID

The Buckeye system utilizes blue nozzle color-coding to ensure technicians can verify the nozzle type from the floor during an audit. This is critical for maintaining NFPA 17A compliance and ensuring the correct nozzle is matched to the correct appliance.

Foil Seal Defense

Each N-1HP is designed to work with specialized foil seals. In a 24/7 commercial kitchen, nozzles are subjected to constant grease rain. The seal protects the discharge orifice from caking, and is engineered to rupture instantly at the precise pressure of a system actuation.

Corrosion-Resistant Metallurgy

The N-1HP is manufactured from solid brass and finished with a premium chrome plating, ensuring the nozzle resists pitting corrosion and maintains the structural integrity of its 3/8" NPT threads for the entire service life of the system.

• Industrial Range Lines: Providing total surface protection for multi-burner configurations.
• High-Volume Griddles: Ensuring a uniform foam blanket across large flat-top cooking surfaces.
• Commercial Ovens: Protecting the interior of ovens where grease-laden vapors can accumulate.
• Institutional Kitchens (Hospitals/Stadiums): Maintaining a safe, code-compliant environment in facilities where rapid recovery and suppression speed are essential.
• System Retrofits: The N-1HP-10 is the standard inventory item for service companies performing repairs or expanding an existing hood's protection.

Precision Aiming Logic

The N-1HP nozzle must be aimed according to the specific Nozzle Aiming Chart found in the Buckeye Technical Manual. Even a 5-degree deviation can result in a dry spot on a griddle or range, allowing a fire to bypass the suppression zone and reach the exhaust filters.

The 6-Month Visual Audit

During every semi-annual inspection, the technician must verify that the foil seal is intact. If a seal is missing or ruptured, the nozzle must be removed and inspected for internal grease accumulation.

Internal Strainer Inspection

During routine service, the nozzle should be checked to ensure the manifold piping has not introduced pipe scale or debris that could lead to a partial discharge.

Wrench-Tight Integrity

When installing the N-1HP onto the discharge pipe, ensure the connection is liquid-tight. A leaking nozzle base will bleed off system pressure, potentially failing to achieve the necessary spray pattern during an actuation.

Can I use the Blue Nozzle for fryer protection?

No. While the N-1HP is versatile, Buckeye often specifies different flow-rated or color-coded nozzles such as the Yellow or Green series for specialized hazards like fryers. Always refer to your original system design drawings to ensure the nozzle type matches the appliance.

Why is this sold in a 10-pack?

For service providers, the 10-pack is the most cost-effective way to manage truck stock. Large-scale kitchen hoods can have 5 to 15 nozzles; having a bulk supply ensures the technician can complete the job without multiple site visits.

Is the foil seal included?

Foil seals are typically sold separately or as part of a recharge kit. It is mandatory to use the specific Buckeye foil seals with the N-1HP to ensure proper rupture performance during discharge.
