The explosion-protected light-
ing concept for clean rooms
The Ex recess-mounted, ceiling
light fittings RLF .. are equipped
with EVG 09 electronic ballasts
and are suitable for two-pin flu-
orescent lamps. These lamps
are used for surface and flush
mounting in ceilings, in particu-
lar in clean rooms where
smooth, flush surfaces are very
important. The area of applica-
tion is in the pharmaceutical
and chemical industries, and ex-
perimental facilities, as well as
in paint shops and spraying cab-
inets.
Designed for easy installation
The housing comprises white-
painted steel sheet with an
op-
tional cover frame for ceiling
mounting. The type RLF-INOX is
made of polished stainless
steel. In addition, it can also be
fixed by means of two M8
drilled holes on the top of the
housing. The hinged, frameless
pane made of 5 mm thick safe-
ty glass is fixed with 3 resp.
4 captive screws and has inside
hinges. The EPDM sealing en-
sures the high degree of protec-
tion IP65.
Long-term safety
Thanks to its large input voltage
range, the latest generation
of
electronic ballasts can be used
internationally and features an
EOL circuit. The dual-channel
structure of the electronic bal-
lasts allows the safe operation
of the second lamp if one lamp
fails.
Versatile
In conjunction with the gener-
ously dimensioned terminal
compartment, the standard,
twin-ended through-wiring
allo
ws a cost-effective installa-
tion. The luminaire switch relia-
bly prevents the light from be-
ing turned on while the cover is
open.
