Phase Template: cip-hold-pressure¶
Hold headspace pressure for a specified drying duration. Follows cip-pressurize in the blowdown sequence. The combination dries the vessel by pushing residual moisture out the drain while the headspace is held at positive pressure.
Where to find it¶
System endpoint → Equipment Library → Phases → cip-hold-pressure.
Parameters¶
| Parameter | Type | Unit | Range | Default | Required |
|---|---|---|---|---|---|
hold_time |
TIME | — | 10s-5m |
2m |
yes |
TIME parameters take duration strings ("45s", "1m30s", "5m"),
not bare numbers.
Required control modules¶
| Role | Module type | Description |
|---|---|---|
pressure_sensor |
analog-sensor | Tank headspace pressure measurement |
Capability¶
mixing
Used in¶
This is a building block, called by the cip-blowdown-op
operation template.
Failure modes¶
This is a Timed phase. See Phases → Timed phase for the full archetype.
Pairs with a hardware-limit alarm on the headspace pressure. Set a timeoutSeconds on the phase as a backstop.
