Flammable gas detector for offshore use

17 July 2009

Offshore Europe stand number 1094 - Crowcon’s IREX infrared (IR) pellistor-replacement flammable gas detector is suitable for offshore use.

IREX is designed to replace pellistor type flammable gas detectors, resulting in faster response times and greatly reduced zero drift.

The detector is capable of detecting methane, butane, propane and many other hydrocarbons.

It has an extremely fast T90 response time of less than four seconds. Excellent zero stability is also achieved, with none of the drift issue associated with pellistors and cables.

IREX allows existing pellistor-based systems to be easily upgraded without any of the costs associated with installing a new control system. Sophisticated systems and algorithms ensure reliable operation at all times, with no adjustments necessary to the detector itself. Zero and span adjustments are performed at the control panel, and gas response tests and calibration can also be done remotely, with test gas simply applied via a tube to the standard weather cover.
IREX is designed to provide over 10 years reliable operation, and as there are no sensors which need replacing and because routine testing requirements are minimised, operating costs during its entire lifetime are minimal. IREX has both ATEX and IECEx approval and is undergoing assessment for IEC61508 SIL 2 compliance.
