Crowcon IRmax Basic Compact Infra-Red Gas Detector
IRmax is a compact, low power and highly rugged infrared gas detector, that delivers rapid, fail-safe detection of methane, butane, propane and many other hydrocarbon gases and vapours. The reliability of IRmax has been proven in hot, cold, wet and saline environments, making it ideal for use offshore. Unlike conventional IR gas detectors, IRmax does not utilise heaters to prevent condensation on windows and mirrors.
IRmax?s unique STAY-CLIR optical components are treated with a highly durable coating that prevents faults due to condensation. As IRmax contains no components for artificially heating optical surfaces, power consumption is dramatically reduced, requiring only 1W of power, typically 75-90% lower than conventional IR gas detectors.
IRmax basic Exd certified infrared (IR) gas detector for hydrocarbon gases and vapours. IRmax is compatible with any 4-20mA control system and is constructed from 316 stainless steel with M20 or 1/2″NPT cable entry. IRmax is ATEX and IECEx certified for use in Gas (Zone 1 & 2) and Dust (Zones 21 & 22) hazardous areas.
Key Features:
Compact size ? requires less space, effort and time to install
Various installation options ? can be wall mounted, fitted to a 50mm (2 inch) pipe or connected to an auxiliary junction box using a choice of mounting accessories
Industry standard 4-20mA output ? IRmax is compatible with virtually any control system
Remote non-intrusive calibration ? the IR display can be mounted up to 30 metres from the IRmax and test gas can be applied without requiring direct access to the detector
Hand-held Intrinsically Safe calibrator ? IRmax detectors fitted with an I.S barrier module can be checked and calibrated using an I.S calibration accessory
STAY-CLIR optics ? prevents condensation on optical components
Low power ? IRmax only consumes 1W of power, enabling small power supplies and battery back up systems to be used
Automatic optical obscuration monitoring ? minimal routine maintenance keeps costs to a minimum
