IRmax

IRmax is a premium quality IR Gas detector designed for protecting facilities against flammable gas hazards and is the perfect choice for protecting new installations or for upgrading safety on existing sites.

IRmax is ultra-compact and delivers rapid, fail-safe detection of hydrocarbon gases and vapours. Featuring dual-wavelength IR sensor technology in a rugged 316 stainless steel package, IRmax is designed to detect methane gas and other potentially explosive hydrocarbons in the harshest conditions.

IRmax does not utilise heaters to prevent condensation on windows and mirrors. Instead, its optical components are treated with a highly durable hydrophobic coating called STAY-CLIR that completely prevents signal faults due to condensation

IR type gas detectors detect tiny reductions in transmitted infrared energy due to absorption by molecular resonation in hydrocarbon gases and vapours. It is essential that the light path of the detector is not obscured by condensation or dirt to ensure dependable hazard detection. Conventionally, the windows and mirrors in IR detectors are heated to prevent condensation forming. Although an effective solution, heating components require significant amounts of power to operate and can result in the build-up of dissolved deposits (such as salt).

As IRmax contains no components for artificially heating optical surfaces, power consumption is dramatically reduced. It requires less than 1 Watt of power, typically 75-90% lower than conventional IR gas detectors. A gas detection system using IRmax detectors therefore requires smaller (and lower cost) power supplies and battery back-up systems. Longer cables can also be used and more detectors can be powered on addressable networks.

A further benefit of the STAY-CLIR coating is resistance to contamination from dirt and dust, rendering routine cleaning of the optical components unnecessary.
