125LB Wheeled Ansul Redline (Foray Dry Chemical)

The Ansul Red Line CR-I-A-150-C-1 is a 125 lb wheeled cartridge-operated fire extinguisher charged with FORAY (monoammonium phosphate) ABC dry chemical — the only wheeled unit in the Red Line 150-C family that provides Class A, B, and C coverage from a single unit. Rated 30-A:160-B:C, it is the correct wheeled specification for mixed-hazard environments where ordinary combustibles, flammable liquids, and electrical equipment all coexist at a scale that hand-portable ABC units cannot address.

FORAY is Ansul's monoammonium phosphate ABC agent — the same agent used across the Red Line hand-portable ABC family, scaled to wheeled capacity. It is the only dry chemical agent in the Red Line wheeled lineup that suppresses all three standard fire classes, making the CR-I-A-150-C-1 the generalist workhorse of the Red Line wheeled family for mixed-hazard industrial environments. The "I" designation confirms the indicator fill cap as standard, and the "CR" designation confirms the corrosion-resistant epoxy finish. The unit carries USCG approval for marine vessel and port facility use.

FORAY ABC Agent: Triple-Class Wheeled Coverage

FORAY (monoammonium phosphate) provides the only wheeled-unit coverage for all three standard fire classes in the Red Line family:

• Class A (Ordinary Combustibles): Monoammonium phosphate undergoes sintering at approximately 350°F, melting to form an oxygen-excluding crust over wood, paper, and textile fires that prevents deep-seated re-ignition. The 30-A rating provides substantial Class A suppression capacity.
• Class B (Flammable Liquids): The agent interrupts the chemical chain reaction in the flame zone, providing rapid knockdown on gasoline, oil, solvent, and fuel fires at the 160-B:C rated capacity.
• Class C (Electrical Equipment): The non-conductive agent is safe for use on energized electrical panels, motors, and process control systems without risk of electrical shock to the operator.

Red Line Wheeled Platform Features

• Indicator Fill Cap: Red stem indicator pops up when the unit is pressurized, providing immediate visual readiness confirmation during monthly inspections without a separate gauge check.
• Corrosion-Resistant Finish: Epoxy paint over polyester powder coat with black anodized fill cap and nozzle body for long service life in marine, offshore, and coastal environments.
• 50-Foot Hose: 3/4 in. x 50 ft discharge hose provides staging flexibility to position the unit at safe distance from the hazard area during deployment.
• Self-Contained Cartridge System: The attached nitrogen cylinder is the only pressure source required — no pressure regulator needed, simplifying activation and reducing maintenance complexity.
• USCG Approved: Meets USCG requirements for marine vessel and port facility fire protection.
• On-Site Recharge: After any discharge, a certified technician can recharge the unit on-site using Ansul-approved modified technical FORAY agent without shop pressurization equipment.

The CR-I-A-150-C-1 is specified for mixed-hazard high-risk environments where Class A coverage is required alongside large-scale flammable liquid and electrical fire suppression:

• Heavy Manufacturing Facilities: Large production areas where ordinary combustible materials — packaging, insulation, structural elements — coexist with flammable process fluids and energized machinery, requiring a single wheeled unit capable of addressing all three fire classes.
• Mining Operations: Underground and surface mining where the mix of combustible materials, fuel, and electrical equipment demands ABC coverage and the Red Line's field recharge capability is essential for remote site operations.
• Offshore Platforms with Mixed Hazards: Process modules or living quarters access points where ordinary combustibles alongside pressurized fuel streams require Class A coverage that a Purple K wheeled unit cannot provide.
• Large Construction Sites: Major project sites where Class A, B, and C hazards all coexist at a scale that warrants wheeled unit deployment.
• Marine Vessels with Mixed Cargo: USCG-approved for vessels where mixed cargo or onboard ordinary combustibles alongside fuel systems require ABC rather than BC-only coverage.

To maintain NFPA 10 compliance and USCG approval, the CR-I-A-150-C-1 must follow a documented maintenance schedule:

• Monthly Visual Inspection: Verify the nitrogen cylinder valve is closed and the safety seal is intact. Check that the indicator fill cap is not pressurized at rest. Inspect the 50-foot hose and nozzle for damage. Confirm inspection tags are current.
• Annual Maintenance: A certified technician must inspect all components, verify nitrogen cylinder condition, check the hose and nozzle assembly, and confirm FORAY agent has not packed or caked. Document on the inspection tag.
• 6-Year Internal Examination: Full internal inspection per NFPA 10 including agent removal and cylinder interior inspection. Recharge with Ansul-approved modified technical FORAY agent only — do not substitute standard Sentry-grade FORAY agent.
• 12-Year Hydrostatic Test: The agent tank must undergo hydrostatic pressure testing per NFPA 10 and DOT requirements to verify structural integrity.

When should I choose this over the CR-I-K-150-C (Purple K) wheeled model?

Choose the CR-I-A-150-C-1 when your hazard assessment requires Class A coverage in addition to Class B and C. The Purple K model (CR-I-K-150-C) carries a higher B:C rating (320-B:C vs 160-B:C) because potassium bicarbonate is more effective per pound on flammable liquid fires than monoammonium phosphate. If your environment has significant ordinary combustible exposure alongside large flammable liquid hazards — manufacturing facilities, mixed-cargo vessels, mining operations — FORAY's ABC coverage makes this the correct specification. If your hazard is purely Class B and C with no meaningful Class A exposure, the Purple K model delivers superior B:C suppression.

Why does this unit weigh more than the Purple K wheeled model at the same 125 lb agent capacity?

The FORAY ABC wheeled model ships at 483 lbs compared to 453 lbs for the Purple K model. The difference reflects the different bulk densities and packaging of the FORAY vs Purple K agents, and minor differences in the tank and hardware configuration for the respective agents.

Can I recharge this unit with standard FORAY agent purchased from a fire supply distributor?

No. All Red Line Class A extinguishers must be recharged with Ansul's modified technical FORAY dry chemical, specifically formulated for the Red Line platform's operating pressures and discharge characteristics. Standard Sentry-grade FORAY agent is not an approved substitute and will not maintain the unit's listed performance.
