Niaar supplies UV/IR Flame Detectors from FGD Fire & Gas Detection Tech and Honeywell — dual spectrum flame detectors, optical flame sensors, explosion proof flame detectors, and SIL rated flame detectors for UAE and GCC projects.
Niaar supplies UV/IR Flame Detectors from leading manufacturers including FGD Fire & Gas Detection Tech and Honeywell. UV/IR Flame Detectors use combined ultraviolet and infrared sensing. They detect a wide range of fire types including hydrocarbon, hydrogen, and alcohol fires. Niaar provides full procurement support for UV/IR Flame Detectors and all dual spectrum flame detector products across the UAE and GCC.
A dual spectrum flame detector combines ultraviolet and infrared sensing channels in a single optical flame detector head. First, the ultraviolet channel responds to UV radiation emitted by virtually all combustion reactions. Second, the infrared channel responds to the characteristic infrared radiation produced by hot combustion gases.
Third, the dual spectrum flame detector uses logical coincidence of both channels to confirm a fire alarm. This approach significantly reduces false alarm rates compared to single-channel UV or IR detectors.
Furthermore, dual spectrum flame detectors from Honeywell and FGD Fire & Gas Detection Tech are available in flameproof Ex d and intrinsically safe Ex ia versions. Therefore, UV/IR Flame Detectors from Niaar cover every hazardous area classification at UAE oil and gas and petrochemical facilities.
Ultraviolet infrared sensors provide wide-area coverage with detection ranges suited to large process areas. First, UV/IR Flame Detectors from Honeywell achieve detection ranges of 20 to 50 metres for typical hydrocarbon fire scenarios. Second, the field of view for ultraviolet infrared sensors is typically 90 degrees cone angle.
This provides broad coverage from each detector position. Third, ultraviolet infrared sensors are available with narrow-field-of-view optics for focused long-range detection in duct and enclosed space applications.
Furthermore, ultraviolet infrared sensors provide optical self-test functions. These periodically verify the sensitivity of both the UV and IR channels without manual intervention. Therefore, UV/IR Flame Detectors from Niaar maintain calibrated performance throughout their service life.
Hydrocarbon fire detection using UV/IR Flame Detectors is standard practice in UAE oil and gas, petrochemical, and refinery facilities. First, UV/IR Flame Detectors detect fires from crude oil, natural gas, diesel, petrol, LPG, and chemical solvents rapidly. Second, optical flame sensor technology responds in under 5 seconds for fires within the detection range.
This is significantly faster than heat or smoke detectors. Third, hydrocarbon fire detection systems using these detectors from Honeywell comply with UAE Civil Defence requirements and ADNOC fire protection specifications.
Furthermore, these detectors provide industrial fire detection at process equipment boundaries, manifold areas, pump stations, and storage facilities. Therefore, these detectors from Niaar are the preferred optical flame sensor for UAE industrial fire detection applications.
Explosion proof flame detectors are required for installation in UAE Zone 1 and Zone 2 classified hazardous areas. First, explosion proof flame detector products from FGD Fire & Gas Detection Tech carry ATEX Zone 1 and IECEx certification.
Second, the Ex d flameproof enclosure of explosion proof flame detectors prevents internal sparks from igniting the external atmosphere. Third, offshore flame detector versions carry additional marine type approval for installation on UAE offshore platforms and FPSOs.
Niaar manages these detectors procurement from hazard assessment through detector selection, ATEX certification review, and delivery. Niaar works with FGD Fire & Gas Detection Tech and Honeywell to supply dual spectrum flame detectors and optical flame sensors for all UAE and GCC industrial fire detection projects.
