For over 40 years Crowcon has been developing and manufacturing high quality products with a reputation for reliability and technical innovation.Crowcon fixed detectors have been proven in many arduous environments, including oil and gas exploration, water treatment, and steel and chemical plants. IRmax offers uniquely low powered, fail-safe detection of hydrocarbon gases and vapours. Choosing the fixed gas detector for your needsIRmaxInfrared Hydrocarbon Gas DetectorPlease see the back page for full technical specifications.Simple to installCompact sizeVarious installation optionsIndustry standard 4-20mA outputOptions for HART communications and RS-485 ModbusRequires less space, effort and time to installCan be wall mounted, fitted to a 50mm (2 inch) pipe or connected to an auxiliary junction box using a choice of mounting acessories IRmax is compatible with virtually any control systemEasy maintenanceRemote non-intrusive calibration Hand-held Intrinsically Safe (I.S) calibratorSTAY-CLIR opticsThe IR Display can be mounted up to 30 metres from the IRmax and test gas can be applied without requiring direct access to the detectorIRmax detectors fitted with an I.S barrier module can be checked and calibrated using an I.S calibration accessoryPrevents condensation on optical componentsLow cost of ownershipLow powerAutomatic optical obscuration monitoringAnnual proof-test interval IRmax only consumes 1W of power, enabling small power supplies and battery back up systems to be usedMinimal routine maintenance keeps costs to a minimumIRmax 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 completely 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 is available either as a basic unit without display, or with three display options. The Fixed IR Display is permanently fixed to the IRmax detector to enable simple status checking and non-intrusive calibration. The Remote IR Display can be mounted up to 30 metres from the IRmax detector, simplifying checking and maintenance of detectors mounted in inaccessible areas. The Hand-Held I.S. Calibrator is available for temporary connection to IRmax detectors fitted with an I.S. Barrier Module.I.S Hand-Held Calibrator• Enables calibration and interrogation of IRmax detectors without a Fixed or Remote IR Display• Only one I.S. hand-held calibrator required per IRmax detector fleet• Intrinsically Safe; suitable for use in hazardous areasRemote IR Display • Can be mounted up to 30 metres from IRmax• Removes the need to directly access the IRmax detector• Choice of connection lead lengthsFixed IR Display• Large, clear display shows gas level and other status information• Simple non-intrusive calibration• Enables connection of hand-held HART communicators• Can be rotated up and down to provide the optimum viewing angleIRmax optionsHART communications• Hand-held HART communicators can be connected to the IR Display for local diagnostics and calibration• HART data is super-imposed onto the 4-20mA signal for communicating with HART enabled control systems• Compatible with point-to-point or addressable HART topologiesRS-485 Modbus• Enables remote interrogation of IRmax• Enables up to 32 detectors to be multi-dropped on an addressable network• RS-485 physical platform for transmission of data up to 1KmCalibration capMounting bracket kitSpigot glandRemote calibration unit Flow adaptorDuct mounting kitI.S remote display connecting leadsAccessoriesAuxillary junction boxwww.crowcon.com UK:Tel: +44 (0) 1235 557700Fax: +44 (0) 1235 557718Email: sales@crowcon.comUS:Tel: +1 859 957 1039Toll Free: 800 527 6926Fax: +1 513 957 1044Email: salesusa@crowcon.usNL:Tel: +31 10 421 1232Fax: +31 10 421 0542Email: eu@crowcon.comSG:Tel: +65 6745 2936Fax: +65 6745 0467Email: sales@crowcon.com.sgCN:Tel: +86 (0) 10 6787 0335Fax: +86 (0) 10 6787 4879Email: saleschina@crowcon.comIN:Tel: +91 22 6708 0400Fax: +91 22 6708 0405Email: salesindia@crowcon.comCrowcon reserves the right to change the design or specification of the product without notice.Check www.crowcon.com for updates.
