150LB Wheeled Ansul Redline (Plus Fifty Chemical)

The Ansul Red Line 150 lb (CR-I-150-C) is a heavy-duty, wheeled fire suppression unit engineered for the most demanding Class B and C environments on earth. In facilities where flammable liquids are stored in bulk—such as fuel terminals, refineries, and aircraft hangars—a handheld fire extinguisher simply lacks the "stay-power" to overcome a rapidly escalating fire. The CR-I-150-C bridges the gap between portable fire protection and fixed systems, providing a single operator with 150 lbs of high-velocity Plus Fifty BC dry chemical agent.

As part of the legendary Red Line series, this unit utilizes a cartridge-operated design. By keeping the nitrogen propellant in a separate external cylinder, the system remains unpressurized during standby, eliminating the risk of gradual leaks. Built with a rugged steel carriage and oversized wheels, the CR-I-150-C is the definitive choice for high-risk operations requiring industrial fire protection.

The Science of Large-Scale Suppression: Kinetic Flow

1. Massive Agent Throughput

In a large liquid fuel fire, heat signatures create powerful thermal updrafts that can deflect the agent from smaller units. The CR-I-150-C is engineered for high-mass flow, delivering over 150 lbs of agent through a long-reach hose. This allows the operator to "overpower" the thermal column—a capability often discussed in industrial "First Strike" tactics.

2. Plus Fifty BC (Potassium Bicarbonate) Kinetics

Plus Fifty C is a premium potassium bicarbonate-based agent. Unlike ABC dry chemical fire extinguisher powder, which melts into a crust, Plus Fifty C works through "Molecular Interference." It is approximately twice as effective as sodium bicarbonate agents on a pound-for-pound basis, making it the industry standard for wholesale fire equipment specifications in high-hazard zones.

3. Cartridge-Operated Reliability

The external nitrogen cartridge ensures that the agent is "fluffed" or fluidized the instant the unit is activated. This prevents the dry chemical from "packing" at the bottom of the tank—a critical feature for units that sit for long periods on docks or in storage.

The "Ansul Red Line" Advantage: Front Line Engineering

• Single-Operator Maneuverability: Despite its 480 lb weight, the unit is balanced on oversized wheels. This allows one person to navigate the unit to reach a fire before the local fire department can mobilize.
• Extended Reach and Stand-off: The unit features a reinforced discharge hose. This allows the operator to maintain a safe distance from intense radiant heat while still delivering agent.
• Simplified On-Site Recharging: Following a discharge, a technician can recharge the unit on-site. There is no need for a complex pressurized recharge, which is a massive logistical advantage for fire equipment companies servicing remote sites.

The Ansul CR-I-150-C is the primary specified choice for "Mega-Hazard" zones where firefighting equipment must be mobile:

• Fuel Storage Terminals: Protecting large-scale manifold areas and pumping stations.
• Oil & Gas Refineries: Providing a mobile capability for high-pressure fuel lines.
• Aircraft Hangars & Tarmacs: The standard for protecting aviation assets during refueling.
• Marine Ports: Ideal for protecting loading docks when used with a USCG approved fire extinguisher bracket system for shipboard engine rooms.

Manufacturer	Ansul (A Johnson Controls Brand)
Model	CR-I-150-C
Unit Type	Wheeled Fire Extinguisher
Agent Type	Plus Fifty BC (Potassium Bicarbonate)
Capacity	150 lbs (68 kg)
UL Rating	160-B:C

To maintain NFPA 10 compliance and ensure your facility passes its fire inspection, the CR-I-150-C must follow a strict protocol:

• Monthly Visual Inspection: Verify tires are inflated and the nitrogen cartridge safety seal is intact. Check that fire extinguisher inspection stickers are current and legible.
• Annual Maintenance: A certified technician must conduct an internal inspection. This is a significantly safer process than auditing stored-pressure units.
• 12-Year Hydrostatic Test: Mandatory to verify the structural integrity of the steel pressure vessel.

Where can I find a fire equipment company that services wheeled units?
You should contact a specialized fire equipment store that is authorized to service Ansul industrial equipment to ensure proper nitrogen cartridge replacement.

Can I use this on an electrical fire?
Yes. Plus Fifty BC is Class C rated, making it safe for energized electrical equipment. It is a much more powerful option than a standard handheld unit for large electrical vaults.

How do I use the PASS method fire extinguisher technique on a wheeled unit?
The PASS acronym for fire extinguisher use is adapted: Open the nitrogen cylinder, Aim the nozzle, Squeeze the discharge lever, and Sweep the base of the fire.
