Gas Fire Extinguishing Systems

Clean-agent systems using HFC-227ea (FM-200) and FK-5-1-12 (Novec 1230 equivalent) — suspended, cabinet-type, pre-engineered, fire detection tube and condensed aerosol formats.

Suspended HFC-227ea (FM-200) Automatic Fire Extinguishing Unit

Composition: agent cylinder, container valve, solenoid actuator, nozzle, temperature-sensing glass bulb, pressure signal feedback device and suspension bracket. No agent distribution piping and no dedicated cylinder room are required — the unit is suspended from the ceiling, making installation fast and wiring simple.

Applications

Computer rooms, data processing centers, telecom facilities, process control centers, high-value medical facilities, valuable industrial equipment, museums and galleries, libraries and archives, valuable goods storage, emergency power facilities, flammable liquid storage areas, clean production rooms; also painting production lines, electrical aging rooms, rolling mills, presses, melting tanks, drying equipment, coal powder silos in cement production, ship engine rooms and cargo holds. Particularly suited to confined spaces.

Cabinet-Type HFC-227ea Fire Extinguishing Unit

HFC-227ea is a highly effective, residue-free, non-corrosive extinguishing agent with high dielectric strength. Cabinet-type units require no dedicated cylinder room and are simple to install and maintain — suitable where distribution piping cannot be installed, or for a single protected zone, and can be positioned flexibly as required.

Applications: computer rooms, telecom rooms, data storage facilities, switchgear rooms, generator rooms, library and archive rooms, and other rooms housing valuable equipment.

Pre-Engineered FK-5-1-12 Fire Extinguishing Device

A complete set of pre-assembled components — agent cylinder group, nozzle and fittings — fixed in place or in a cabinet and arranged directly in the protected volume. Together with the fire alarm control equipment it forms an automatic detection and extinguishing system. No pressure storage; safe, reliable, electrically non-conductive and clean.

Fire Detection Tube Extinguishing Device

Point-to-point suppression for small and complex flammable spaces: the detection tube itself delivers the agent directly to the fire source. Temperature self-actuating, no power supply required, immune to electromagnetic, humidity and dust interference. Simple design, easy installation, suitable for unattended equipment.

  • Agents: HFC-227ea / FK-5-1-12
  • Filling amount and storage pressure: custom (per application)
  • Tube diameter: φ18 mm (customizable)

Condensed Aerosol Extinguishing Device

Small size, flexible configuration, no pressure storage. Non-conductive, non-toxic, non-corrosive, zero ozone depletion. High extinguishing efficiency with full-flood coverage; easy installation, maintenance-free.

  • Starting mode: thermal cord actuation / electric double opening
  • Valid service life: ten years
  • Full parameter table available on request
