Request Information

ANSUL's flagship cartridge-operated dry chemical line — the industry benchmark for high-hazard industrial fire protection. The defining feature: extinguishing agent is stored separately from the nitrogen expellant cartridge, so there is no stored pressure in the main cylinder between uses. No slow leaks, no pressure loss over time — making RED LINE consistently more reliable than stored-pressure units in harsh outdoor, extreme-temperature, or high-vibration environments.


Meets or exceeds ANSI/UL 299, UL 711, ULC S504 and S508. UL Listed and FM Approved. DOT and USCG approved with proper bracket. Field rechargeable. Four sizes: 5, 10, 20, and 30 lb.


Available variants:

  • High Flow (HF) — special nozzle for maximum discharge rates on pressurized fuel fires (per NFPA 10, Sections 5.5.1.1.1 and 5.5.1.1.2)
  • Low Temperature (LT) — nitrogen cartridge rated to -65°F
  • Corrosion Resistant (CR) — zinc-rich primer + super durable polyester oven-cured topcoat; black anodized hose couplings and metal parts
  • Ring Pin (RP) — secondary protection against accidental actuation
  • Mil-Spec 20-E and 30-E — available on request

Agent options: FORAY (Class A/B/C), Purple-K (Class B/C), or specialty agents for specific hazards.
