dHLS 85... for high pressure discharge lamps
Metal version for Zone 1
Description
The explosion-protected pendant light
fittings dHLS 85... for high pressure discharge
lamps are in accordance to the
ATEX-Directive 94/9/EG as well as the
European Norms EN 50014, EN 50018 and
EN 50019. They are certified for use in the
Zones 1 and 2.
The housing is made of a light alloy with a
powdered coating. The pressed-in threadring
for the flameproof thread gap is made
of brass. This provides for an easy lamp
replacement even after a longer operating
periods.
The pendant light fitting was designed for
outdoor use. Due to the high safety standard
it has more than proven its reliability in
chemical factories and offshore platforms
for illuminating large areas and selective
large objects.
The light fitting is fitted with a dome-shaped
glass cover and can also be fitted with an
external reflector.
