350LB Wheeled Ansul Redline (Foray Dry Chemical)

The Ansul Red Line CR-I-A-350-C-1 is a 350 lb wheeled cartridge-operated fire extinguisher charged with FORAY (monoammonium phosphate) ABC dry chemical agent — the only agent in the Red Line wheeled family that provides Class A, B, and C coverage from a single unit. With a UL/ULC rating of 40-A:240-B:C, this is the generalist workhorse of the Red Line 350 lb line, designed for high-hazard environments where ordinary combustibles, flammable liquids, and electrical equipment all coexist and a single portable suppression unit must be capable of addressing any of them.

FORAY is monoammonium phosphate (MAP) dry chemical — the same active ingredient used in hand-portable ABC extinguishers, scaled to 350 lbs of agent in a self-contained wheeled unit. On Class A fires, the MAP agent undergoes sintering at approximately 350°F, melting to form an oxygen-excluding crust that prevents re-ignition of deep-seated embers in wood, paper, and textiles. On Class B fires, it interrupts the chemical chain reaction of the flame. On Class C hazards, the non-conductive agent allows safe suppression of energized electrical equipment. The attached nitrogen cylinder is the only pressure source required to expel the full 350 lb charge.

Why Choose FORAY Over Purple K or PLUS-FIFTY C

Purple K and PLUS-FIFTY C are BC-only agents — they are not effective on Class A fires. In environments where ordinary combustibles are present alongside flammable liquid and electrical hazards, FORAY's ABC coverage eliminates the need to stage multiple agent types. The trade-off is that FORAY is less effective per pound than Purple K on Class B fires. Facilities where Class B is the dominant hazard typically select Purple K for maximum suppression efficiency on flammable liquid fires. Facilities where mixed hazard types are present select FORAY for versatility.

Red Line C Model Platform

• Large Diameter Steel Wheels: Wheel centerline near center of gravity for single-operator maneuvering to the fire source.
• Two-Position Ball Valve Nozzle: Aluminum barrel for solid, round agent stream delivery with stop-start control during approach.
• Indicator Fill Cap: Red stem pops up when unit is pressurized for immediate visual readiness confirmation.
• On-Site Recharge: Cartridge-operated design allows field recharge without shop pressurization equipment.

The CR-I-A-350-C-1 is the right choice for high-hazard environments where multiple fire classes must be covered by a single wheeled unit:

• Heavy Manufacturing Facilities: Protecting areas where wood, paper, and packaging materials coexist with flammable lubricants, cutting fluids, and energized machinery — a mixed-hazard profile that demands ABC coverage.
• Paint Spray Booths and Coating Operations: Protecting areas with flammable solvent vapors (Class B) and accumulated overspray on combustible surfaces (Class A).
• Loading Docks and Warehouses: Areas with high-piled combustible storage and material handling equipment using flammable fuels.
• Chemical Plants and Industrial Facilities: Process areas where ordinary combustibles, flammable process streams, and electrical equipment all require coverage from a single staged unit.

To maintain NFPA 10 compliance, the CR-I-A-350-C-1 must follow a documented maintenance schedule:

• Monthly Visual Inspection: Verify the nitrogen cylinder safety seal is intact, wheels and tires are undamaged, and the nozzle and hose are free of damage or obstruction. Confirm inspection tags are current.
• Annual Maintenance: A certified technician must inspect all internal components, verify nitrogen cylinder condition, check the hose and nozzle assembly, and confirm the FORAY agent has not packed or caked. Document findings on the inspection tag.
• 6-Year Internal Examination: Full internal inspection per NFPA 10 including agent removal, cylinder interior inspection, and component replacement as needed before recharge with fresh FORAY agent.
• 12-Year Hydrostatic Test: The welded steel agent tank must undergo hydrostatic pressure testing to verify structural integrity.

Why does this unit have a lower B:C rating than the Purple K version?

Purple K (potassium bicarbonate) is approximately twice as effective per pound as monoammonium phosphate on Class B flammable liquid fires. The 350 lb FORAY unit is rated 240-B:C while the 350 lb Purple K unit is rated 480-B:C for the same agent volume — reflecting the difference in agent efficiency per pound. If your primary hazard is flammable liquids, Purple K delivers more B:C suppression power per pound. If you need Class A coverage in addition to B and C, FORAY is the correct choice.

Can this unit be used on a cooking grease fire?

While FORAY is a Class B rated agent, commercial kitchen grease fires require a UL 300-listed Class K wet chemical agent and a portable Class K extinguisher. FORAY does not provide the saponification and sustained cooling that Class K fires require. Do not substitute this unit for Class K protection in commercial kitchen environments.

Can one person operate the CR-I-A-350-C-1?

Yes. The Red Line C Model is designed for single-operator deployment. The wheel centerline near the unit's center of gravity makes maneuvering manageable for a trained industrial fire responder despite the 922 lb shipping weight.
