30LB Ansul Redline Cartridge (High Flow & Corrosion Resistant) (FORAY)

The Ansul Red Line CR-HF-I-A-30-G-1 is a 30 lb corrosion-resistant, high-flow cartridge-operated hand-portable fire extinguisher charged with FORAY (monoammonium phosphate) ABC dry chemical — the most fully specified unit in the Red Line 30 lb hand-portable family. It combines three key features: the corrosion-resistant epoxy finish for marine and salt air environments, the high-flow nozzle configuration for pressurized liquid and gas fires, and FORAY ABC agent for Class A, B, and C coverage. Rated 40-A:120-B:C, it is the correct specification when all three requirements — corrosion resistance, high flow, and ABC coverage — must be met by a single unit.

Per NFPA 10, high flow extinguishers are specifically designed for pressurized flammable liquid and gas fires where agent flow rate is critical to extinguishment. The CR-HF-I-A-30-G-1 delivers FORAY at a high flow rate in an epoxy-finished cylinder that withstands the aggressive salt air, humidity, and chemical vapor environments of offshore platforms, coastal facilities, and marine vessels — while still covering Class A ordinary combustible fires that the BC-only agents cannot address. Every unit includes an Indicator Fill Cap and a Corrosion Resistant Cap as standard features.

The Complete Specification: CR + HF + ABC

Most high-hazard installations can be served by a simpler model. The CR-HF-I-A-30-G-1 exists for facilities where no simpler combination works:

• CR (Corrosion Resistant): Epoxy-based paint system over polyester powder coat for enhanced protection in salt air, marine, and chemical vapor environments where standard coatings deteriorate prematurely.
• HF (High Flow): Factory-configured high-flow nozzle for pressurized flammable liquid and gas fires per NFPA 10 — situations where standard flow rates cannot overcome the fuel supply rate of a pressurized fire.
• A (FORAY ABC): Monoammonium phosphate agent covering Class A ordinary combustibles in addition to Class B flammable liquids and Class C electrical equipment — necessary when ordinary combustible materials are present alongside pressurized fuel hazards.

Additional Included Features

• Indicator Fill Cap: Red stem indicator pops up when pressurized for immediate visual readiness confirmation during inspections.
• Corrosion Resistant Cap: Protects the fill opening against moisture and corrosive atmosphere ingress.
• Field Recharge: Cartridge-operated design allows on-site recharge by a certified technician. Must use Ansul-approved modified technical FORAY agent (pail part no. 434906).
• 12-Year Limited Warranty: Ansul's 12-year limited warranty from date of delivery.

The CR-HF-I-A-30-G-1 is the correct specification for facilities requiring all three features simultaneously:

• Offshore Platforms with Mixed Hazards: Process modules, living quarters access points, and utility areas on offshore platforms where salt air demands corrosion resistance, pressurized process streams demand high flow, and ordinary combustible materials demand Class A coverage.
• Coastal LNG and LPG Facilities: Marine terminals handling liquefied gas where pressurized gas fire risk, salt air exposure, and surrounding ordinary combustibles all coexist.
• Marine Vessels with Cargo and Fuel Hazards: USCG approved for shipboard use. Vessels carrying mixed cargo or operating in environments where pressurized fuel systems, Class A cargo materials, and salt air all factor into the extinguisher specification.
• Coastal Refineries and Chemical Plants: Waterfront process facilities where the full combination of corrosion resistance, high-flow capability, and ABC coverage is required at a single staging location.

To maintain NFPA 10 compliance and USCG approval, the CR-HF-I-A-30-G-1 must follow a documented maintenance schedule:

• Monthly Visual Inspection: Verify the nitrogen cartridge safety seal is intact, the pull pin and tamper seal are in place, and the corrosion-resistant cap is undamaged. Inspect the epoxy cylinder finish for chips or corrosion breakthrough. Confirm inspection tags are current.
• Annual Maintenance: A certified technician must inspect all components including the corrosion-resistant finish, verify nitrogen cartridge condition, check the high-flow nozzle assembly, and confirm FORAY agent has not packed or caked.
• 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 (pail part no. 434906) only.
• 12-Year Hydrostatic Test: The carbon steel agent tank must undergo hydrostatic pressure testing per NFPA 10 and DOT requirements.

When should I choose this over the CR-HF-I-K-30-G (Corrosion Resistant High Flow Purple K)?

Choose the CR-HF-I-A-30-G-1 when your hazard assessment requires Class A coverage in addition to Class B and C. If your installation is in a marine or coastal environment with pressurized fuel fire risk but no significant Class A exposure — such as an open deck area with no ordinary combustibles — the CR-HF-I-K-30-G's Purple K agent provides higher B:C suppression efficiency per pound. If ordinary combustibles are present alongside the pressurized fuel hazard, FORAY's ABC coverage makes this the correct specification.

Is the corrosion-resistant finish the same on both CR models?

Yes. Both the CR-HF-I-K-30-G and the CR-HF-I-A-30-G-1 use the same epoxy-based paint system over polyester powder coat. The difference between them is the agent type — Purple K (BC only) versus FORAY (ABC) — which determines the appropriate hazard classification.

Can this unit be recharged with standard FORAY agent?

No. All Red Line Class A extinguishers must be recharged with Ansul's modified technical FORAY dry chemical (pail part no. 434906), which is specifically formulated for the Red Line platform's operating pressures and flow rates. Do not substitute standard Sentry-grade FORAY agent — it will not maintain the unit's listed performance characteristics.
