Problem this solves
- Throughput and profile control are often a trade-off in packed columns.
- Instability can force slower runs to protect quality.
- Manual balancing increases operator burden in long shifts.

iStill NextGen Feature
Packed Column
Packed column helps with passive reflux, the seperation of alcohols and provide the best transition possible between cuts.
Fit profile
Best for
- Distilleries seeking more capacity from existing floor space.
- Operations balancing output and profile consistency.
Not ideal for
- Setups running only occasional low-throughput experimental batches.
How it works
Mechanism in practice
- Reflux capacitor supports condensation and reflux management in the column.
- Improved internal reflux behavior stabilizes run conditions.
- Control system can maintain target behavior while increasing effective throughput.
- Operators retain recipe consistency with less manual balancing effort.
Decision table
Conventional vs NextGen
| Criterion | Conventional setup | iStill NextGen |
|---|---|---|
| Packed-column output | Lower output to stay stable. | Higher output with controlled run behavior. |
| Stability under load | More prone to drift as rate increases. | Improved stability at productive run settings. |
| Operational tuning | Frequent intervention to keep profile. | Less corrective balancing during production. |
Benefits
- Increases productive capacity without abandoning quality targets.
- Supports steadier run behavior in packed column mode.
- Improves operational confidence at higher output settings.
Requirements & limits
- Requires compatible column configuration and commissioning.
- Cooling and heating circuits must be sized correctly.
- Teams should validate final throughput versus product quality goals.

FAQ
Common questions
What does "up to 20%" depend on?
It depends on recipe, run strategy, hardware configuration, and commissioning quality.
Does higher output reduce quality?
Not inherently. The feature is intended to increase output while maintaining controlled behavior.
Can existing users retrofit this approach?
Retrofit options depend on machine generation and configuration.
