The device assumes
max. the temperature of
the cleaning medium or
that of the container,
plus 10 °C of intrinsic
heating. The result
is a max. surface
temperature of the
device of 70 °C.

T70 °C Da Heating to 60 °C is possible, plus
10 °C intrinsic heating results in
a maximum surface temperature of the
non-electrical part of 70 °C. Ambient
temperature outside max. 40 °C.
The electrical equipment has a max.
surface temperature of T95 °C.
This results in the maximum surface
temperature of T95 °C.

If potentially explosive
mixtures outside
atmospheric conditions are
possible in the container, the
cleaning process is not part
of the intended use under
these conditions and
requires a separate hazard
assessment.
