Ansul Red Line Fire Extinguishers – Nationwide Shipping from Serviced Fire Equipment

What is an Ansul Red Line fire extinguisher?

The Ansul Red Line is a cartridge-operated dry chemical fire extinguisher manufactured by Ansul, a brand of Johnson Controls. It is one of the most widely specified extinguishers for high-hazard industrial environments — oil and gas, mining, aviation, petrochemical, and heavy manufacturing. Unlike stored pressure extinguishers the Red Line uses a separate expellant gas cartridge to propel the dry chemical agent, which means the cylinder is not pressurized until the extinguisher is activated. This design provides superior reliability, simplified maintenance, and the ability to recharge in the field without specialized equipment.

What is the difference between a cartridge-operated and stored pressure extinguisher?

A stored pressure extinguisher keeps the propellant gas and extinguishing agent in the same cylinder under constant pressure. A cartridge-operated extinguisher like the Ansul Red Line stores the expellant gas — CO₂ or nitrogen — in a separate cartridge outside the agent cylinder. The cylinder is not pressurized until the cartridge is punctured at the moment of use. This has several advantages: the unit is easier to inspect and maintain since there is no pressure to work around, the cartridge can be replaced in the field for immediate recharge, and the design eliminates the risk of slow pressure loss that can render stored pressure units non-functional without visible indication.

What sizes do Ansul Red Line extinguishers come in?

Ansul Red Line hand portable extinguishers are available in four sizes — 5 lb, 10 lb, 20 lb, and 30 lb. The 5 lb model is compact and designed for vehicles, mobile equipment, and tight spaces. The 10 lb is the most common size for general industrial use with UL ratings up to 4-A:40-B:C. The 20 lb handles heavy-risk environments with ratings up to 6-A:60-B:C. The 30 lb is the largest in the hand portable line with ratings up to 10-A:80-B:C and 120-B:C depending on agent — suited for aviation, mining, and fuel loading applications. Wheeled models are also available for large-area coverage requirements. Contact us at (727) 620-3473 to confirm current availability for specific models.

What agents are available for Ansul Red Line extinguishers?

Ansul Red Line extinguishers are available with several dry chemical agent options depending on the hazard:

• FORAY® (Monoammonium Phosphate) — multi-purpose agent effective on Class A, B, and C fires. The most common agent for general commercial and industrial use
• Purple-K® (Potassium Bicarbonate) — the most effective Ansul agent for fast knockdown of Class B flammable liquid and Class C electrical fires. Preferred for aviation, oil and gas, and petrochemical applications
• PLUS-FIFTY C® (Sodium Bicarbonate) — reliable Class B and C protection. Compatible with protein-based foam agents making it suitable for combined agent attack
• LITH-X® — for Class D combustible metal fires involving lithium and lithium alloys
• MET-L-X® and MET-L-KYL® — for Class D fires involving sodium, potassium, magnesium, and pyrophoric materials

Can Ansul Red Line extinguishers be recharged in the field?

Yes — this is one of the most significant operational advantages of the cartridge-operated design. After discharge the expellant cartridge is replaced and the cylinder is refilled with the correct dry chemical agent. Because the cylinder is not pressurized until activation there is no need to depressurize the unit before servicing. Field recharge can be performed by a trained technician without the specialized equipment required for stored pressure extinguishers — minimizing downtime in critical operations. All recharges must be performed by a licensed fire equipment technician to ensure proper agent type, fill quantity, and NFPA 10 compliance.

What industries use Ansul Red Line extinguishers?

Ansul Red Line extinguishers are the preferred choice wherever fire risk is high and reliability is non-negotiable. Common industries and applications include oil and gas refineries, petrochemical plants, mining operations, utilities and power generation facilities, metal processing and welding areas, paint booths and spray finishing facilities, aviation and aircraft hangars, fuel storage and loading areas, heavy construction and earthmoving equipment, and military installations. If your operation is classified as a high-hazard environment under NFPA 10 the Red Line is almost certainly the right extinguisher for your application.

How often do Ansul Red Line extinguishers need to be serviced?

Ansul Red Line extinguishers follow NFPA 10 maintenance requirements with some cartridge-specific additions. Required service intervals include monthly visual inspections by the user or facility staff, annual professional inspection and certification by a licensed technician, 6-year internal examination and recharge, and hydrostatic testing of the cylinder every 12 years. The expellant cartridge must also be inspected annually and replaced if the weight loss exceeds the manufacturer's specification — typically 10% of the net cartridge weight. Cartridges showing any sign of corrosion, damage, or leakage must be replaced immediately regardless of weight.

Do you service and recharge Ansul Red Line extinguishers?

Yes. Serviced Fire Equipment services and recharges Ansul Red Line cartridge-operated extinguishers at our St. Petersburg walk-in facility. We perform annual inspection and certification, cartridge replacement, agent recharge, 6-year internal maintenance, and DOT-authorized hydrostatic testing — all in-house with no outsourcing. Local customers can drop off directly. Customers outside the Tampa Bay area can ship units to our facility. Contact us at (727) 620-3473 to discuss service requirements for your specific models.

What is the warranty on Ansul Red Line extinguishers?

Ansul Red Line extinguishers carry a twelve-year limited warranty against defects in materials and workmanship when properly maintained according to NFPA 10 and Ansul service procedures. The warranty covers the cylinder and major components — not the expellant cartridge or dry chemical agent which are considered consumable service items. Warranty claims are handled through Ansul's Johnson Controls service network. Proper annual inspection and documented service history are required to maintain warranty coverage. Contact us for details on specific warranty terms for the model you are purchasing.
