Spectrex 40/40UFI Ultra Fast Triple IR (IR3) Flame Detector

Spectrex 40/40UFI Ultra Fast Triple IR (IR3) Flame Detector

Flame Detector

Hazardous Area | ATEX Certified

Spectrex flame detectors are trusted and specified throughout the UK and international hazardous area industries to provide reliable flame detection in potentially explosive atmospheres according to IECEx and ATEX (Zone 1 & Zone 2).

The Spectrex 40/40UFI, an Ultra-Fast multispectrum IR3 Flame Detector manufactured by Spectrex, detects hydrocarbon fuel and gas fires at long distances, and is especially designed to detect an explosive 1 ft (0.3m) diameter gas cloud explosion in max. 50 msecs for 1ft diameter sphere methane-air mixture explosion at 66 ft (20m) with the highest immunity to false alarms.

The 40/40UFI IR3 can also detect a 1 ft2 (0.1m2) gasoline/n-Heptane pan fire at up to 300 ft (90m).

The Spectrex 40/40UFI is part of the 40/40 Series, the most durable and weather resistant range of flame detectors currently on the market.

Features of the flame detector include a heated window, to eliminate condensation and icing; HART capability for digital communications; lower power requirements; and a compact, lighter design.

Due to increased reliability, the 40/40 Series warranty period has been extended to 5 years and is SIL2 (TUV) approved per IEC 61508.

 ➡ T&D Sales Team are able to support the specification and supply of their flammable and toxic gas detectors. Additionally, T&D are CompEx Certificated and competent in understanding hazardous area classifications and site requirements for the sale of explosion and flameproof equipment.

Flame, Heat, Gas Detectors & Detection Systems

ATEX Beacon

Hazardous area industries including offshore oil/gas platforms and FPSOs, onshore oil refineries, processing plants, pipelines, storage farms and LPG/LNG plants all utilise or produce a wide range of hazardous flammable liquids and gases that can be detected using correctly specified flame and gas detectors.

Detecting toxic and flammable gases requires the detectors to be classified and certified according to the specific IECEx or ATEX standard – we distribute flame detectors manufactured by Spectrex to operate in the harshest environmental conditions including self-contained stand-alone devices designed for direct connection to control and alarm systems or automatic fire extinguishing systems.

Our range of Hazardous Area Fire & Gas Detection System products also includes Explosion Proof Warning Systems – comprehensive range of intrinsically safe, flameproof and explosion proof alarm sounders, sirens, bells and horns, loudspeakers and beacons.
