Heat insulation – FMD77
The FMD77 must only be insulated up to a certain height. The maximum permitted insulation height is labelled
on the devices and applies to an insulation material with a heat conductivity
0.04 W/(m x K) and to the maximum permitted ambient and process temperature (
see table below). The
data were determined under the most critical application "quiescent air".
