10LB Ansul Redline Hand Portable (Plus Fifty Chemical)

The Ansul Red Line 10 lb Hand Portable charged with PLUS-FIFTY C is a cartridge-operated dry chemical fire extinguisher designed for Class B and C fire hazards in high-risk industrial environments. PLUS-FIFTY C is a sodium bicarbonate-based BC dry chemical that provides rapid knockdown of flammable liquid and energized electrical fires. Unlike the ABC FORAY-charged Red Line models, the PLUS-FIFTY C version does not protect Class A (ordinary combustible) fires. It is specified in environments where a highly effective BC agent is required and where monoammonium phosphate (from ABC dry chemical) would cause unacceptable corrosion damage to equipment or facilities.

The cartridge-operated design is a defining feature of the Red Line family. Rather than storing pressurized agent and propellant gas together in the same cylinder (as in stored-pressure units), the Red Line uses a separate nitrogen or CO2 cartridge. When the user operates the unit, the cartridge is punctured internally and the released gas pressurizes the agent cylinder to drive the discharge. This design means the cylinder is at atmospheric pressure during standby, significantly reducing the risk of slow agent degradation from compaction, and allows the unit to be recharged on-site by a trained technician by simply replacing the expended cartridge and refilling the agent cylinder.

Red Line Cartridge-Operated Advantages

• On-Site Rechargeability: The unit can be fully recharged in the field without returning it to a service shop. The technician replaces the spent cartridge and refills the agent, returning the unit to service immediately.
• Standby Reliability: The cylinder is unpressurized during storage, eliminating the slow pressure-leak failure mode of stored-pressure units and ensuring the agent remains loose and free-flowing regardless of vibration or temperature cycling.
• Agent Selection: The Red Line platform accommodates multiple agents (PLUS-FIFTY C, FORAY ABC, Purple-K, and specialty Class D agents) in the same hardware, allowing one bracket infrastructure to serve different hazard types by agent swap.
• 12-Year Limited Warranty: The Red Line carries a 12-year limited warranty, reflecting Ansul's confidence in the carbon steel shell and all-metal components.

• Fuel Loading Racks and Petroleum Storage: The BC-rated PLUS-FIFTY C is preferred for petroleum facilities where Class A rating is not the primary concern and where MAP agent residue would damage equipment.
• Heavy Construction and Mining Equipment: Vehicle-mounted on underground mining equipment, excavators, and large off-road machines where fuel, hydraulic fluid, and electrical fire risks are constant.
• Oil Pumping Stations and Process Lines: Where flammable liquid hazards dominate and corrosion-sensitive instrumentation must be protected from MAP agent residue.
• Paint Lockers and Solvent Storage: For Class B flammable liquid hazards in commercial and industrial painting operations.

Why choose PLUS-FIFTY C instead of FORAY ABC agent in the Red Line?

FORAY (monoammonium phosphate) is the ABC agent and is more versatile, covering Class A, B, and C fires. PLUS-FIFTY C (sodium bicarbonate) is BC-only but leaves a less corrosive residue. Facilities with sensitive electronics, precision instrumentation, or galvanized metal surfaces often specify PLUS-FIFTY C to minimize post-discharge equipment damage even when Class A protection is not the primary concern. Your local fire safety authority or industrial hygienist can advise on the correct agent for your specific hazard.

Can this extinguisher be recharged on-site?

Yes. The cartridge-operated Red Line design allows trained technicians to recharge the unit on-site by replacing the expended nitrogen or CO2 cartridge and refilling the agent cylinder with fresh PLUS-FIFTY C dry chemical. This eliminates the need to transport the unit to a service shop and minimizes downtime in remote or high-unit-count facilities.
