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. Gases or vapors of explosion
groups IIA or IIB.
The cleaning process (spraying
of fluids) in the presence of
explosive mixtures with
ignition-sensitive substances
in accordance with
Section 2.1
and Section 3.3 is not
permitted. Group IIC gases are
NOT permitted during cleaning.
T6 Ga Heating to 60 °C is possible, plus 10 °C
intrinsic heating results in a max. surface
temperature of the non-electrical part of
70 °C. Ambient temperature outside
max. 40 °C. The electrical equipment has
temperature class T6.
This results in temperature class T6.
Gases or vapors of
explosion group IIA, IIB

equipment and the non-
electrical part meet the
requirements of
explosion group IIC. T6 Gb

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 100 °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. --- --- Temperature monitoring on the pneumatic
cylinder necessary!
Heating to 90 °C is possible, plus 10 °C of
intrinsic heating results in a maximum
surface temperature of the non-electrical
part of 100 °C, which results in
temperature class T5.
Ambient temperature outside of max.
40 °C. The electrical equipment has
temperature class T6.
This results in the overall temperature
class T5.
