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