• Resistance to media and contamination does not mean that functional safety is
guaranteed in every case.
– Liquids that thicken as they evaporate and become highly viscous or adhesive
(sticky) can lead to malfunctions.
– If they get carried onto systems with rollers, media which have a lubricating effect
can lead to a reduction in the drive power that can be transmitted via friction.
In such instances, special care must be taken when planning the system, and the
maintenance intervals must be correspondingly shortened.
