The Willow 100CPM Counter Pressure Canning Line is designed for breweries and carbonated beverage producers that need reliable in-house canning with consistent fill quality, stable carbonation, and lower oxygen pickup. With throughput up to 100 cans per minute, or approximately 6,000 cans per hour, it gives production teams a practical packaging solution for growing craft breweries and beverage producers scaling from entry-level or mid-speed equipment.

Using isobaric counter-pressure filling, the system equalizes pressure between the product tank and the can before filling. This helps control foaming, preserve carbonation, reduce product loss, and support more consistent package quality for beer, cider, kombucha, hard seltzer, sparkling water, soda, RTD beverages, and similar carbonated drinks.

The Willow 100CPM line supports an integrated filling and seaming workflow, operator-focused controls, sanitary production practices, and repeatable day-to-day operation. It is a strong fit for teams that need higher daily output with a still manageable automated footprint without losing control over product quality or packaging schedules.

For producers upgrading from smaller equipment, mobile canning, or lower-speed packaging systems, Willow provides a scalable path toward controlled in-house canning, better production planning, and more consistent finished cans.

Willow is built with Siemens PLC/HMI control, Schneider VFD, a 12-valve isobaric filling system, and a 4-head seamer based on the current product information.

- 12-valve isobaric filling system for stable counter-pressure filling

- 4-head seamer for reliable high-speed can sealing

- Siemens PLC/HMI and Schneider VFD support precise automated control

- Counter-pressure filling helps reduce foaming, preserve carbonation, and support lower DO

- Supports common can formats with 60–180 mm height adjustment

- Ideal for growing craft breweries and beverage producers scaling from smaller systems

Q1: Who is the Willow 100CPM canning line best suited for?

A: It is best suited for breweries and beverage producers that need higher daily output with a still manageable automated footprint, consistent fill quality, and a controlled in-house packaging workflow.

Q2: How fast can the Willow 100CPM run?

A: The Willow 100CPM is designed for up to 100 cans per minute, or approximately 6,000 cans per hour, depending on product conditions, carbonation level, can format, and final configuration.

Q3: What filling method does this canning line use?

A: It uses isobaric counter-pressure filling, which pressurizes the can before filling to help reduce foaming, preserve carbonation, and lower oxygen pickup.

Q4: Why is counter-pressure filling important for carbonated beverages?

A: Counter-pressure filling helps control CO₂ breakout and foam during filling. This supports more consistent fills, better carbonation retention, reduced product loss, and improved package quality.

Q5: What beverages can be packaged on this system?

A: It is suitable for beer, cider, kombucha, hard seltzer, sparkling water, soda, RTD cocktails, and other carbonated beverage applications.

Q6: Can it support different can sizes?

A: Yes. Changeover options are available for common beverage can formats such as 12 oz, 16 oz, and 500 mL, depending on the final setup.

Q7: Is this system suitable for low-DO packaging goals?

A: Yes. The counter-pressure filling process is designed to support lower dissolved oxygen pickup compared with uncontrolled open filling.

Q8: What maintenance should operators expect?

A: Typical maintenance includes routine inspection of seals, lubrication of moving parts, CO₂ system checks, and cleaning procedures based on the production schedule.

Q9: Is installation and training available?

A: Yes. Redwood can support installation, operator training, spare parts planning, and ongoing technical support based on the final project scope.

Q10: When should a producer choose the Willow 100CPM instead of another speed?

A: Choose the Willow 100CPM when your expected canning volume, labor plan, and production schedule match growing craft breweries and beverage producers scaling from entry-level or mid-speed equipment. Smaller or larger Redwood systems may be a better fit depending on your growth stage.

Yasuharu Takeuchi

I completed the second brew yesterday. The hop basket you made worked extremely well, and I was able to brew an IPA using homegrown hops.

Everything is functioning smoothly so far, and I think the brewing equipment is very well designed.

Thank you very much!

Best regards,

We couldn't be more impressed with the quality and service Wang and his team have provided us. Redwood Stainless engineers had no problem drawing and executing our custom tank design,which no one else would do. All of our tanks came outfitted with high quality fittings,valves,and carb stones. The welds are beautiful, and these fermenters are a real showpiece.
