Description
Ansul Red Line CR-I-K-350-C | 350 LB Wheeled Purple K Fire Extinguisher | 480-B:C

The Ansul Red Line 350 lb (CR-I-K-350-C) is the most powerful portable fire suppression asset in the Ansul arsenal. Engineered for mega-hazard environments where a fire involving thousands of gallons of fuel is a statistical possibility, this unit provides a single operator with an unprecedented volume of Purple K (Potassium Bicarbonate) agent.

With a massive UL/ULC rating of 480-B:C, the CR-I-K-350-C is designed to suppress nearly 500 square feet of deep-layer flammable liquid fire in a single discharge. As a cartridge-operated unit, it utilizes external nitrogen cylinders to propel the agent. Built on a rugged steel carriage with oversized wheels, it is the definitive choice for industrial fire protection.

The Physics of Elite Suppression: Purple K Micro-Kinetics

1. Potassium Bicarbonate (Purple K) Interference

Purple K is widely regarded as the most effective dry chemical agent for Class B fires. At a molecular level, it interferes with the free radicals in the fire's chemical chain reaction. It is approximately twice as effective as sodium bicarbonate, allowing for faster knockdown of even the most aggressive fuel fires.

2. Mass-Flow Rate and Thermal Column Penetration

Large-scale fuel fires create massive thermal updrafts that can deflect the agent from a standard fire extinguisher. The CR-I-K-350-C is calibrated for high mass-flow, delivering over 350 lbs of agent through a specialized high-volume nozzle. This allows the operator to punch through the fire's heat column — a technical requirement for refinery and fuel terminal protection.

3. Dual-Cartridge Fluidization

To move 350 lbs of powder effectively, the unit utilizes high-pressure nitrogen. Upon activation, the gas enters the bottom of the tank and fluidizes the Purple K powder into a consistent, flowable state. This prevents agent caking and ensures a steady discharge from start to finish.

The Red Line Advantage: Engineered for Extreme Readiness

  • Strategic Mobility: Despite its 922 lb total weight, the unit is balanced for rapid deployment. Large-diameter wheels allow a single operator to navigate industrial aisles.
  • Extended Stand-Off Safety: The unit features a 50-foot reinforced discharge hose, allowing the operator to engage a fire from up to 40 feet away and stay protected from radiant heat.
  • Simplified Field Serviceability: After a discharge, the CR-I-K-350-C can be recharged on-site without requiring a pressurized service shop refill — a major logistical advantage for remote industrial operations.

The Ansul CR-I-K-350-C is the primary choice for high-volatility zones where portable fire protection must be absolute:

  • Petrochemical Refineries: Protecting manifold areas where a leak can result in a massive three-dimensional fuel fire.
  • Fuel Storage Terminals: Providing the high-volume suppression required for protecting tank farms.
  • Airport Tarmacs: The standard for protecting aviation assets where rapid knockdown is non-negotiable.
  • Offshore Rigs: Ideal for protecting loading docks and engine rooms in confined environments.
Feature Details
Manufacturer Ansul (A Johnson Controls Brand)
Model CR-I-K-350-C
Unit Type Wheeled Cartridge-Operated Fire Extinguisher
Agent Type Purple K (Potassium Bicarbonate)
Capacity 350 lbs (159 kg)
UL/ULC Rating 480-B:C
Total Weight 922 lbs
Discharge Hose 50 Feet (Reinforced)
Effective Range Up to 40 Feet
Certifications UL Listed, NFPA 10 Compliant

To maintain NFPA 10 compliance and ensure your facility passes its fire inspection, the CR-I-K-350-C must follow a strict maintenance protocol:

  • Monthly Visual Inspection: Verify tires are inflated and nitrogen safety seals are intact. Confirm inspection tags are current and visible.
  • Annual Maintenance: A certified technician must conduct an internal inspection of all components, nitrogen cartridge condition, and hose integrity.
  • 12-Year Hydrostatic Test: Mandatory to verify the structural integrity of the steel pressure vessel.

Where can I find service and maintenance for large wheeled units like this?

Visit a specialized fire equipment store or an authorized Ansul dealer to ensure proper maintenance of these high-capacity industrial assets.

Is this more effective than a standard 10 lb Purple K unit?

Yes. While a handheld Purple K unit is appropriate for small spills, the 350 lb unit provides the mass flow needed to suppress nearly 500 square feet of fire — a task that no hand-portable unit can match.

How do you operate this unit during an emergency?

The approach is similar to the PASS method adapted for wheeled cartridge units: open the nitrogen cartridge valve to pressurize the tank, aim the long-range nozzle at the base of the fire, squeeze the discharge lever, and sweep across the base of the fire from a safe 30 to 40 foot distance.
