IR flammable gas detector

IRmax is an ultra-compact
infrared (IR) flammable gas
detector from Crowcon
which 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.

Unlike conventional IR gas
detectors, 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.

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.
