The Fir 50CPM 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 50 cans per minute, depending on final configuration and product conditions, it gives production teams a practical packaging solution for craft breweries and beverage producers moving beyond pilot-scale packaging into more regular production runs.

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 Fir 50CPM 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 manageable mid-speed production with room to grow without losing control over product quality or packaging schedules.

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

Fir is a good fit when the team needs more output than a 25CPM line but is not ready for a 100CPM or larger high-speed system.

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?

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 Fir 50CPM instead of another speed?

A: Choose the Fir 50CPM when your expected canning volume, labor plan, and production schedule match craft breweries and beverage producers moving beyond pilot-scale packaging into more regular production runs. 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.
