2D dust maximum surface temperature in case of use in area of Zone 21
T≤+80°C...205°C
The maximum surface temperature of the operating mate-
rial depends on the operating temperatures of the fluid and
the am-bient temperature and is 5 K higher than the operat-
ing tempera-ture at the installation site.
