ProDetec supplies advanced infrared flame detectors designed to deliver rapid, reliable fire detection in Australia’s most demanding industrial environments. Our IR flame detector solutions are trusted across oil & gas, mining, chemical processing, energy infrastructure, and emerging hydrogen applications, where early flame detection is critical to protecting people, assets, and operations.
Infrared flame detection technology provides fast response to hydrocarbon fires, even in harsh outdoor conditions where smoke, dust, wind, or low visibility can compromise traditional fire detection methods. With over 20 years of experience in industrial safety systems, ProDetec delivers engineered infrared flame detection solutions supported by local expertise, compliance knowledge, and long-term service support.
An infrared flame detector is a specialised fire detection device that identifies the unique infrared radiation emitted by flames during combustion. Unlike smoke or heat detectors, IR flame detectors can detect fire almost instantaneously, often within milliseconds, making them ideal for high-risk, fast-escalation environments.
An IR flame detector continuously monitors its field of view for specific infrared wavelengths produced by burning fuels such as hydrocarbons, hydrogen, alcohols, and other industrial gases or liquids. When these wavelengths are detected in the correct pattern and intensity, the detector triggers an alarm or activates protective systems.
Infrared flame detection is widely used where fires may be invisible to the naked eye, where rapid ignition is possible, or where early detection is essential to prevent catastrophic escalation.
Infrared flame detection works by sensing the infrared radiation emitted by flames. Different fuels emit characteristic IR signatures, which advanced detectors are designed to recognise while rejecting background noise from sunlight, hot machinery, or process equipment.
Modern IR flame detectors use optical sensors and signal processing algorithms to analyse:
Once the detected signal matches a known flame signature, the detector activates alarms, shuts down systems, or triggers fire suppression responses. Integration with broader safety systems, including gas detectors and emergency shutdown logic, ensures a coordinated response to fire and gas hazards.
Different industrial environments require varying levels of sensitivity, speed, and false-alarm immunity. ProDetec supplies a full range of infrared flame detectors to suit varied risk profiles.
A triple IR flame detector uses three separate infrared sensors, each tuned to a different wavelength. This allows the detector to compare signals and confirm true flame signatures while rejecting false sources. IR3 technology significantly improves detection reliability and is widely adopted in:
Triple IR detectors offer high immunity to sunlight, hot objects, and process radiation, making them ideal for safety-critical applications that require fast, dependable flame detection.
UV/IR detectors combine ultraviolet and infrared sensing technologies to detect flames across a broader range of fuel types. The UV sensor provides rapid initial detection, while the IR sensor confirms flame presence to reduce false alarms.
These detectors are effective in environments where both speed and selectivity are essential, offering a balanced solution for mixed-risk sites.
Selecting the right IR flame detector requires careful consideration of technical performance and compliance requirements.
Detection range varies by model and technology, with advanced detectors capable of identifying flames at distances exceeding 60 metres. Proper placement and coverage analysis ensure reliable detection across the protected area.
Infrared flame detectors offer ultra-fast response times, often under 100 milliseconds. This rapid detection is critical in environments where fire spread can occur almost instantaneously.
Advanced signal processing enables modern infrared flame detectors to distinguish real flames from false sources such as sunlight, welding arcs, hot machinery, or reflections. This reduces nuisance alarms and improves operational confidence.
ProDetec’s IR flame detectors are certified to SIL2 or SIL3 under IEC 61508, ensuring suitability for safety-instrumented systems. ProDetec supplies detectors compliant with Australian and international safety standards.

An IR flame detector senses specific infrared wavelengths emitted by flames and analyses their intensity and flicker patterns to identify fire while rejecting false sources.
IR detectors sense infrared radiation, while UV detectors sense ultraviolet light. IR detectors are generally more immune to false alarms caused by sunlight and are better suited for outdoor environments.
Yes. Advanced infrared flame detectors, particularly multi-spectrum models, can detect hydrogen fires that may be invisible to the human eye, such as ProDetec’s SG50 offering.
Potential sources include reflected sunlight, hot machinery, or process radiation. ProDetec’s detectors minimise false alarms through multi-sensor verification and advanced signal processing.
Detection range depends on detector type and flame size, but many industrial IR flame detectors can detect fires at distances of up to 60 metres or more when correctly installed.
