The history of recovering CO₂ from the fermentation process dates back to 1912, the year Wittemann pioneered the closed fermentation process. Since then, brewers and distillers around the world rely on Wittemann to design, build, install and maintain their own in-house CO₂ Recovery System.

Wittemann engineers analyze fermentation schedules and brewing data and calculate CO₂ availability for optimal plant sizing. Systems can be desinged to recover CO₂ from sources with an inlet purity as low as 80%, producing final product purities as hight as 99.998%.

Microbrewers to large scale brewers and distillers can benefit from Wittemann's proven process for purifying, compressing and liquefying CO₂. Recent advancements in these processes maximize efficiency and product purity - once again proving Wittemann's role as the leader in CO₂ recovery technology. CO₂ produced from a Wittemann recovery system ensures your product is free of objectionable tastes and odors.
