11.2 Environment
11.2.1 Ambient temperature
-10 to +70 °C (+10 to +160 °F)
11.2.2 Storage temperature
-10 to +70 °C (+10 to +160 °F)
11.3 Process
11.3.1 Process temperature
For all materials except PVDF, PVDF conductive and PP
–10 to 140 °C (14 to 284 °F)
PVDF and PVDF conductive
–10 to ¹⁰⁰⁄₉₀ °C (14 to ²¹²⁄₁₉₄ °F)
PP
0 to 60 °C (32 to 140 °F)
11.3.2 Process pressure range
Pneumatic drive
16 bar (232 psi) up to 140 °C (284 °F)
Manual drive 8 bar (116 psi) up to 140 °C (284 °F)
The service life of the seals is reduced if process temperatures are constantly high or if
SIP is used. The other process conditions may also reduce the service life of the seals.
Process pressure for pneumatic drive
Materials Basic version Immersion chamber version
1.4404, Alloy C22, PEEK 16 bar (232 psi) to 140 °C (284 °F) 16 bar (232 psi) to 140 °C (284 °F)
PVDF, PVDF conductive 16 bar (232 psi) to 100 °C (212 °F) 4 bar (58 psi) to 90 °C (194 °F)
PP (polypropylene) 6 bar (87 psi) to 20 °C (86 °F) -
The service life of the seals is reduced if process temperatures are constantly high or if
SIP is used. The other process conditions may also reduce the service life of the seals.
Depending on the version, the process pressure must be reduced to insert/retract the
assembly.
