Crowcon IREX

Fixed Gas Detector

Using Infrared & Pellistor Technology

Low Power, Accurate Detection Of Hydrocarbon Gases 

Crowcon IREX Fixed Gas Detector

The Crowcon IREX is a fixed gas detector that replaces the pellistor heads by simply mounting on the original junction box and connecting to the original cable.

T&D can offer the IREX fixed gas detection soltuion for use in harsh industrial environments.

The Crowcon IREX fixed gas detector enhances the pellistor gas detector to an IR gas detector without a costly changeover.

Pellistor sensor technology has provided a cost effective fixed gas detection solution however pellistor gas detectors aren’t without there limitations.

Pellistor gas detector sensors can be poisoned and require regular maintenance.

They typically need to be updated every 3-5 years and operate behind a flame arrestor which often gets blocked stopping the gas from reaching the sensor.

Pellistors may burn-out if exposed to gas concentrations in excess of 110% LEL and can only function correctly when certain amount of oxygen is present in the atmosphere.


Pellistor Gas Detector

Crowcon’s IREX fixed gas detector overcomes all of the above issues.
