Phoenix Explosion-Proof Extruded Aluminium Camera Housings‚
ATEX Certified for IIB Applications

The "Phoenix Explosion-Proof" equipment is ATEX-certified to be used
in potentially hazardous areas where there is a risk of explosion
because flammable gases‚ vapours‚ mists or dusts may be present. The
housing is designed to prevent explosion by containing any heat‚
sparks‚ or flames generated. This prevents ignition of potentially explo-
sive atmospheres or materials outside the equipment. The housing is
ATEX-certified for use in IIB gas environments (includes ethylene and
propane). The housing is supplied complete with heater & sun shield.
The housing can be factory-fitted with a wiper and integral 10 or 17fn
AC Telemetry Receiver.

Siemens can deliver this housing as a factory pre-built version with
Siemens or customer-supplied camera and lens. Therefore one of the
Phoenix-FIT options must be ordered.
Please note‚ that Siemens cannot supply ATEX IIB Equipment certifi-
cates unless one of the Phoenix-CERT option is ordered with each
housing.
