A counter pressure canning line is used to fill carbonated beverages into cans under pressure, maintaining equilibrium to prevent foaming and minimize dissolved oxygen pickup. The Willow 100CPM is designed for craft breweries and beverage producers who are ready to scale their packaging while maintaining consistent product quality.

This system is ideal for breweries upgrading from manual or atmospheric fillers to a reliable, automated solution. It delivers stable performance at 100 cans per minute (approximately 6,000 cans per hour), helping reduce product loss and improve packaging efficiency.

Featuring a 20-valve isobaric filling system and a 4-head seamer, the Willow 100CPM achieves ≥98% filling efficiency with precise and repeatable results. Built on a SUS304 stainless steel frame with Siemens PLC and HMI control, it provides a durable, scalable canning solution for growing beverage operations.

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.
