A sealing system for
infrared emitters
developed by Heraeus
Noblelight has been
granted IP65
certification. The
sealing system allows
the use of infrared
systems for outdoor
heating processes,
where it will protect
against the ingress of
dirt or spray water.

The infrared
emitters are made
from hard-wearing, shock-resistant
quartz glass, so are well suited for
outdoor applications. The electrical
connectors for such emitters are fed
into the connection box via a special
seal. The system underwent testing
by VDE, the German
Certification body
and proved totally
sealed to dust and
spray, conforming
with and satisfying
VDE 0710 DIN40050,
relating to IP65.

Heraeus says
infrared offers
benefits in terms of
its high efficiency and
heat transfer capacity,
fast response, heat
transfer without
contact and ability to match the IR
emitter to the product in terms of
optimum IR wavelength and emitter
shape.
