Crowcon IREX Fixed Gas Detector

Overview

IR Technology versus Pellistor

Pellistors do not fail safe	Sensors can be ‘poisoned’ and rendered insensitive to gas by silicones, lead, sulphurs and chlorinated compounds.
Pellistors are high maintenance	Sensors must be regularly tested with gas to ensure they are stilloperational. Sensors typically last 3-5 years, after which they must beexchanged.
Pellistors must be operated behind a sinter (flame arrestor)	Sinters may become blocked, thus preventing gas from reaching thesensor.
Pellistors may burn out	If exposed to gas concentrations in excess of 110% LEL.
Pellistors need oxygen	Their ability to detect gas reduces significantly in oxygen deficientatmospheres

Low power

IREX consumes less than 1W of power – ensures compatability with a wide range of control systems

Dependable

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
