Ansul 3N Nozzle (new style) - 443327

The Ansul 3N Nozzle is a high-capacity, mission-critical component of the world-renowned Ansul R-102 Restaurant Fire Suppression System. While smaller nozzles are designed for duct and plenum protection, the 3N nozzle is specifically engineered for high-risk, high-volume cooking appliances that require a concentrated, powerful application of ANSULEX Low pH Liquid Fire Suppressant.

Designated as a "3-Flow" nozzle, it delivers three times the flow rate of a standard 1-flow nozzle, allowing for the protection of larger hazard areas with a single discharge point. This reduces the complexity of piping in commercial kitchen hoods and ensures that even the most aggressive grease fires are neutralized in seconds.

Why the "3N" Designation Matters

• Higher Volume: Discharges a greater volume of ANSULEX agent per second compared to any other nozzle in the R-102 lineup
• Targeted Suppression: Atomizes liquid agent into fine droplets, maximizing surface area coverage and cooling effect
• System Efficiency: Protect large appliances using one nozzle instead of three separate 1-flow nozzles, reducing installation costs

Precision Engineering & Durable Construction

• Chrome-Plated Brass Body: Heavy-duty chrome finish that resists corrosion and simplifies cleaning
• Laser-Etched Identification: "3N" designation laser-etched directly onto the nozzle body for easy verification
• Metal Blow-Off Cap Included: Stainless steel cap protects the nozzle from grease clogs while instantly detaching during system actuation

Applications & Strategic Use Cases

• High-Proximity Broilers requiring immediate "flood" of wet chemical agent
• Large Surface Griddles with wide cooking surfaces
• Heavy-Duty Charbroilers with intense heat and flames
• Industrial Kitchens in stadiums, hospitals, and large hotel banquet facilities

The Ansul 3N nozzle is not a "general purpose" nozzle; it is a specialized tool for specific hazard types defined in the Ansul R-102 Design and Installation Manual.

Where the 3N Nozzle Excels:

• High-Proximity Broilers: Used for appliances where the fire hazard is intense and requires an immediate "flood" of wet chemical agent
• Large Surface Griddles: Ideal for covering wide cooking surfaces where a 1N or 2N nozzle would provide insufficient volume to suppress a flash fire
• Heavy-Duty Charbroilers: Designed to penetrate the rising heat and flames of charcoal or gas-radiant broilers to reach the fuel source
• Industrial Kitchens: Frequently specified in stadiums, hospitals, and large hotel banquet kitchens where appliances are significantly larger than standard restaurant equipment

Maintenance and Inspection Requirements

• Monthly Visual Check: Ensure the metal blow-off cap is in place and nozzle is not heavily coated in hardened grease
• Semi-Annual Professional Inspection: Certified fire technician should remove nozzle, check internal strainer, and ensure orifice is clear
• Cap Replacement: Replace damaged or missing metal blow-off cap immediately to prevent grease from entering piping system

When it comes to fire safety, compliance isn't optional—it's a legal requirement. The Ansul 3N nozzle is rigorously tested and listed to meet the highest global standards:

• UL 300 Listed: The gold standard for restaurant fire suppression, tested to handle the high temperatures of modern vegetable oils
• NFPA 17A & NFPA 96: Fully compliant with National Fire Protection Association standards for wet chemical extinguishing systems and commercial cooking ventilation
• OEM Reliability: As a genuine OEM (Original Equipment Manufacturer) part from Johnson Controls, the Ansul 3N nozzle is the exact component required to maintain your R-102 system's UL listing. Using non-genuine parts can void insurance policies and fail fire marshal inspections

Frequently Asked Questions

Can I replace a 1N nozzle with a 3N nozzle for "extra" protection?
No. Fire suppression systems are "pre-engineered." Replacing a 1N with a 3N without a professional redesign can lead to the system running out of agent before the fire is out or insufficient pressure at other nozzles. Always follow the system's specific design drawing.

Does this nozzle work with Amerex or Buckeye systems?
No. The Ansul 3N nozzle is specifically listed and calibrated for use with the Ansul R-102 system and ANSULEX agent. Using it in other systems will void the UL listing of the entire installation.

Why does the nozzle have a metal cap instead of rubber?
Metal caps are more durable in high-heat areas directly above broilers. They provide a more secure seal against grease vapors while still detaching reliably under system pressure.
