Infra-red pellistor replacement flammable gas detector
IREX is a sinter-free, fully featured infrared gas detector that produces an mV Wheatstone Bridge output as used on conventional pellistor based systems.
IREX replaces old pellistor heads by simply mounting on the original junction box and connecting to the original cable. The IREX concept enables upgrade to dual-wavelength IR gas detector technology without incurring the very significant costs associated with replacing the control system and re-installation.
IREX consumes less than 1W of power - ensures compatability with a wide range of control systems
Independantly tested for reliability and performance in harsh offshore conditions by Micropack Engineering Ltd - demonstrates IREX will operate dependable in any application
3rd party approval to the performance standard EN60079-29-1
Employs sophisticated systems and algorithms - ensures reliable operation at all times
T90 response time of less than 4 seconds - rapid indication of hydrocarbon gas hazards
Optical components are treated with a STAY-CLIR coating - prevents partial obscuration in condensing atmospheres
Easy to maintain
No adjustments are necessary at the detectors, zero and span adjustments (if required) are performed at the control panel only - saves significant time and cost
Test can be applied remotely via a tube to the standard weather cover
Sinter-free operation - unlike a pellistor sensor, there is no risk of a sinter becoming blocked
