5.3 Temperature data for operation in Zone 1 / Div. 1
Model name Surface temperature
FEP315 / FEH315
FEP515 / FEH515
70 °C (158 °F)
FEP325 / FEP525 85 °C (185 °F)
FET325 / FET525 70 °C (158 °F)
The surface temperature depends on the fluid temperature.
With increasing fluid temperature > 70 °C (158 °F) or > 85 °C (185 °F) the surface temperature also increases to the level of the fluid
temperature.
Note
The maximum permissible fluid temperature depends on the lining and flange material, and is limited by the operating values in Table 1 and the
explosion protection specifications in Tables 2 ... n.
