Crowcon Fgard IR3 Flame Detector

The Crowcon Fgard IR3 flame detector is an explosion proof multi spectrum infrared (IR) flame detector, responding to hydrocarbon liquid fuel and gas fires even at long distances.

The Crowcon Fgard IR3 is an explosion proof multi spectrum infrared (IR) flame detector, responding to hydrocarbon liquid fuel and gas fires even at long distances. It delivers first-in-class flame detection, with intelligent heated optics for clearer results and advanced optical verification to greatly reduce false alarms.

A 0.1 m² n-heptane fire is detected at up to 60 m in under five seconds, and outputs cover 0–20 mA, HART® and alarm and fault relays for integration into any fire and gas system.

Hinco Instruments supplies, services and calibrates Crowcon’s flame detectors and fixed gas detectors in Western Australia. Contact us for pricing and availability.

Applications

The Crowcon Fgard IR3 is an explosion-proof flame detector for hydrocarbon fire risks where a false alarm is as costly as a missed one:

  • Oil and gas production, separation and processing facilities
  • Offshore platforms, FPSOs and marine loading terminals
  • Refineries, petrochemical plants and tank farms
  • Fuel storage, bunding and road/rail loading gantries
  • Turbine halls, compressor stations and gas pipeline facilities
  • Aircraft hangars, fuelling aprons and maintenance bays
  • Mining workshops, fuel bays and heavy vehicle refuelling areas
  • Chemical storage warehouses and solvent handling areas
