Phase Template: cip-pressurize¶
Pressurize tank headspace with N₂ to a target pressure, then close the N₂ valve. Used during CIP blowdown to force residual rinse water out of the vessel and drain lines.
Where to find it¶
System endpoint → Equipment Library → Phases → cip-pressurize.
Parameters¶
| Parameter | Type | Unit | Range | Default | Required |
|---|---|---|---|---|---|
target_pressure |
REAL | bar | 0.5-3.0 | 1.5 |
yes |
pressurize_time |
TIME | — | 10s-1m |
15s |
yes |
TIME parameters take duration strings ("45s", "1m30s", "5m"),
not bare numbers.
Required control modules¶
| Role | Module type | Description |
|---|---|---|
pressure_controller |
analog-control | N₂ blanket pressure controller |
pressure_sensor |
analog-sensor | Tank headspace pressure measurement |
Capability¶
mixing
Used in¶
This is a building block, the first phase of the
cip-blowdown-op operation template.
Failure modes¶
This is a PV-endpoint phase. See Phases → PV-endpoint phase for the full archetype.
Pairs with a TagHighHigh overpressure alarm. Set a timeoutSeconds on the phase as a backstop.
