IR hydrocarbon detector

Crowcon’s new IRmax is an
ultra-compact infrared (IR)
gas detector which delivers
rapid, fail-safe detection of
hydrocarbon gases with very
low power consumption. Far
smaller and lighter than
comparable IR detectors, the
IRmax is easy to install in
even the most inaccessible
locations, says Crowcon.

Featuring dual-wavelength
IR sensor technology in a
rugged 316 stainless steel
package, IRmax is designed
to operate in the harshest
conditions in temperatures
ranging from -40 to +75°C.

Unlike conventional IR gas
detectors, IRmax does not
utilise heaters to prevent
condensation on windows
and mirrors – instead it has
STAY-CLIR optical
components, which are
treated with a highly durable
coating that prevents faults
due to condensation.

Because IRmax contains
no components for artificially
heating optical surfaces,
power consumption is
dramatically reduced – the
device requires only 1 Watt of
power, 75-90% lower than
conventional IR gas detectors.

IRmax detectors require
smaller and lower cost power
supplies and battery back-up
systems. In addition, low
power consumption also
means longer cables can be
used and more detectors can
be powered on addressable
networks.
