1) The sterilization temperature is only valid for steam (saturated steam) or superheated water.
2) Longer sterilization times or continuous operation on request.
3) If the sterilization temperatures listed above are applied to the EPDM diaphragms for longer periods of time,
the service life of the diaphragms will be reduced. In these cases, maintenance cycles must be adapted ac-
cordingly. This also applies to PTFE diaphragms exposed to high temperature fluctuations. The mainten-
ance cycles must be adapted accordingly.
