Explosion-proof, UL-844 and C-UL/CSA C22.2 No. 137 listed,
electric lighting fixtures are used in hazardous (classified)
locations. Lights for single port viewing have been designed
to meet the needs of our customers who require lighting and viewing
through a single sightglass.
Designated the REX-100 and the SLEX-100, both models use highintensity halogen lamps to provide bright, glare-free illumination of
the interior of vessels, tanks, hoppers, silos, mixers,
and other normally closed containers in hazardous locations
requiring explosion-proof equipment. The REX-100 is provided with
a highly polished internal reflector which increases the
illumination intensity.
The explosion-proof light can be supplied mounted to the
upper flange of our circular sightglass to form a complete light/
sightglass assembly. The light fixture can also be mounted to
our smaller viewing diameter sightglasses such as 3-1/4" and
4" to form illumination ports. The illumination port used in
conjunction with a standard sightglass offers the user many options.
A typical option would be the use of a video or TV camera on the
free sightglass while the illumination port
provides the necessary lighting.
The explosion-proof light fixtures can also be easily mounted to
existing sightglasses by means of the slotted brackets provided.

q Lighting fixture is mounted to outer sightglass flange,
completely external to vessel pressure.

q The fixture can easily be mounted on existing pressure vessel
installations by means of brackets provided.
q The corrosion resistant fixtures are made of copper-free
(less than 0.004 copper content) aluminum alloy–No. 356T6.
q Castings have heavy walls to withstand internal explosions
without damage. They will also contain and extinguish the
flames of burning gases–before they ignite the surrounding
atmosphere.
