Explanation:
The maximum surface temperatures each result from the maximum permissible ambient or operating temperature T
a
plus the maximum
temperature increase
T of 20 K which has to be taken into account.
1) The ambient or operating temperature T
a
is limited to + 90 °C (valid for T-PUR
®
only: + 120 °C) due to the permissible permanent
operating temperature of the elastomers used.
2) The maximum surface temperature of + 110 °C (valid for T-PUR
®
only: + 140 °C) applies for the use in locations which are potentially
subject to dust explosion, too.
