Crowcon ATEX infrared gas sensors for flammable gases
Compact, extremely robust infrared gas detector ATEX with the lowest power consumption for monitoring combustible concentrations of methane, butane, propane and many other hydrocarbon gases and vapors.
IRmax is a premium quality infrared gas detector designed to protect facilities from flammable gas hazards.
- Fast Response: with a response time of just 4 seconds, IRmax provides rapid detection of hydrocarbon hazards.
- Wide operating temperature range: IRmax is fully temperature compensated in environments from -40 to +75°C.
- Reliable detection: IRmax works even if the optical system is 90% obscured by salt or other contaminants. The degree of obscuration (contamination) can be easily checked with the IR display. An error signal is generated at 90% obscuration.
- Proven: IRmax has undergone extensive long-term testing by independent organizations for reliability in hot, cold, wet and salty environments.
Application examples: chemical plants, steel plants, petrochemicals, water treatment, gas extraction, oil extraction, sewage treatment plants, etc.
