iStill NextGen Feature

Air Pressure Control

Automatically adjusts run behavior when weather-driven pressure changes would normally shift cut points.

Stabilizes spirit profile across changing atmospheric conditions.

Runs stay repeatable despite air pressure shifts.

Problem this solves

  • Weather and barometric pressure changes can move boiling behavior enough to impact quality.
  • Manual operators need to constantly watch and tune cut timing.
  • Small pressure swings create batch-to-batch inconsistency.

Fit profile

Best for

  • Distilleries prioritizing repeatability and quality consistency.
  • Sites with frequent weather swings.

Not ideal for

  • Teams that only run occasional one-off experimental batches.

How it works

Mechanism in practice

  1. Sensors monitor the process state while APC tracks ambient pressure behavior.
  2. The control layer recalculates cut logic when pressure changes during the run.
  3. Heads, hearts, and tails transitions are corrected automatically without manual intervention.
  4. Operators can keep recipe intent while reducing corrective actions during production.

Benefits

  • Keeps cut strategy aligned with recipe targets during pressure changes.
  • Reduces manual corrections on unstable weather days.
  • Improves repeatability for teams running multiple batches per week.

Requirements & limits

  • Requires a calibrated control setup and stable sensor inputs.
  • Recipe baselines should be validated during commissioning.
  • Performance depends on proper condenser and heating tuning.

FAQ

Common questions

Does APC remove the need for recipe tuning?

No. APC improves stability around your recipe, but commissioning and recipe setup still define the target behavior.

Is APC useful in stable climates?

Yes. It still protects run consistency when pressure shifts happen unexpectedly.

Can APC help new operators?

Yes. It reduces one source of variability that usually requires manual experience.
