IRMAX
Crowcon IRmax is a compact, low-power and highly rugged infrared fixed detector for methane, butane, propane and many other hydrocarbon gases and vapours.
It can be supplied as a detector only, with a local or remote gas and status display, and with non-intrusive calibration via an intrinsically safe calibration tool or HART communicator.
Typical uses: hydrocarbon processing, fuel storage, gas plant and process areas.
Alarm set points should follow your risk assessment, site standard and the detector's capability, using the UK workplace exposure limits in HSE EH40 as a reference; flammable gas alarms are typically set at 10% and 20% LEL. We can help you choose sensors and set points for your site.
We supply fixed detection to your specification or your consultant's design, and our engineers service and calibrate installed systems on site, typically every six or twelve months. Call 01489 326031 for advice or a quote.
SIMPLE TO INSTALL
- Its compact size requires less space, effort and time to install
- 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 is compatible with virtually any control system
- Options for HART communications and RS-485 Modbus
EASY MAINTENANCE
- Remote non-intrusive calibration means the remote display can be mounted up to 30 metres from the IRmax, and test gas applied without requiring direct access to the detector
- Fitted with an I.S barrier module, the device can be checked and calibrated using an I.S handheld display
- STAY-CLIR optics prevents condensation on optical components, for clear readings at all times
LOW COST OF OWNERSHIP
- Only consumes 1W of power, meaning small power supplies and battery back-up systems can be used
- Minimal routine maintenance keeps costs down
- Annual proof-test interval
