With a proven track record, DALUM helps craft breweries become self-sufficient by capturing and using their own CO2, eliminating CO2 cost and cutting carbon emissions. Whether you want to boost efficiency or enhance your brewery’s sustainability, The DALUM CO2 Recovery Plants offer a smart, circular solution tailored to modern craft brewing.
The DALUM CO2 Recovery Plants are “big brewery” technology scaled down, designed, and priced for craft breweries.
The plant promotes a circular utilization of the brewery’s CO2 by recovering the CO2 from fermentation. It is collected, purified, liquefied, stored, and ready to be used in all steps of beer production.
As a complete CO2 recovery system, the plant reduces the brewery’s CO2 emission and gives a reliable and cost-efficient supply of CO2 – making your brewery more suited for the future. We estimate that for every kg of CO2 recovered, 2 are saved from not sourcing*
The plants are available in 4 different sizes covering capacities from 1,000 hL/y to 50.000 hL/y.
At DALUM Beverage Equipment, we are proud to meet the growing demand and need for craft breweries to access affordable and advanced technology.
During the fermentation process, breweries naturally release large volumes of CO2 as a byproduct. CO2 is later purchased for use in carbonation, packaging and pressurization. This industrial CO2 is often purchased at an increasing price and with an unpredictable supply.
Recovering CO2 on-site offers a smarter, more sustainable alternative. By capturing, purifying and liquefying the CO2 emitted during fermentation, breweries can use their own recovered CO2 in the production processes. This not only reduces reliance on external suppliers and but also enhances operational efficiency and supports sustainability goals.

*Storage tanks for liquid CO2 needs approvals and inspections.
The DALUM CO2 plant is designed for craft breweries to recover own CO2 from fermentation and CO2 from purging of tanks. The goal is to assist breweries control their own CO2 supply and become self-sufficient. The process of CO2 recovery can be split into several proceses: collection, purification, liquefaction and storage.
The raw form of CO2 is collected from the fermentation tanks using flexible hoses connected to the existing tank’s CIP/gas outlet and to one of the central CO2 collection stations connection points.
Each of the connection points is equipped with a bunging valve or a check valve, and a shut off valve to ensure individual and continuous system operation without risk of cross contamination. If individual fermentation pressures are needed, bunging devices must be used instead of check valves.
The purification takes place in 3 steps before and after compression and liquefaction. The CO2 raw gas from the collection system is supplied to the foam trap where the foam is seperated. After the foam trap but before the CO2 gas reaches the compressor, 90% of the impurities like alcohol, other volatiles and aerosols, are removed in the water scrubber. After compression the gas is dried and further purified in aluminium oxide-based dehydrators, which also removes traces of remaining volatiles. The Dehydrator is duplicated and regenerates automatically by heating. If needed an activated carbonfilter can be installed for H2S removal. To remove incondesabler gases, the liquied CO2 is destilled in the DALUM patented condenser and in a small reboiler and stripper column.
The CO2 is compressed to be liquefied for rectification and compact storage and unlike conventional CO2 compressors, The DALUM three stage CO2 Compressor provides up to 45 bar pressure, hence the CO2 condensation takes place at 0-5 degree Celsius. This makes it unnecessary to use a separate CFC or ammonia cooling systems, but a glycol, ice-water or alcohol coolant system can be.
The dry and compressed CO2 is liquefied in in the condenser using an external coolant source and the liquid CO2 is continuously distilled to ensure low oxygen content. Liquid CO2 is pushed with 35-40 bar pressure to the CO2 storage tank, where liquid CO2 expands to the storage tank pressure and temperature. Vaporized CO2 from the storage tank is sent back to the compressor.
DALUM offers a wide range of storage tanks from 100 liters to 50 tons and all tanks delivered from DALUM is adapted for CO2 recovery including high pressure storage option to reduce vaporization, flash gas return function, seperate CO2 filling line for low loses, chiller option and integrated ambient or glycol regenerable vaporizers.
DALUM can also take care of nessecary filters, regulators and safety devices for userlines. For breweries filling sparkling water using recovered or industrial CO2, DALUM always recommend to use final polishing filters after vaporizer and line regulator as the final step before a sterile filter and usage.
DALUM also offer cylinder filling stations designed to integrate seamlessly with our CO2 recovery plants and storage tanks, the station ensures smooth transfer of recovered CO2 into individual cylinders for further use or distribution.
The DALUM CO2 Recovery Plant is integrated with a self-diagnosing software, that can be remotely accessed via cloud services by PC and mobile devices. The live dashboard provides relevant data and statistics to monitor the CO2 Plant and tank system. The integrated router allows for easy software updates and online service by DALUM Beverage Equipment e.g., troubleshooting services.
CO2 recovery involves capturing and reusing carbon dioxide produced during brewing, reducing costs, lowering emissions, and enhancing sustainability.
By providing a consistent and pure source of CO2, recovery systems ensure uniform carbonation and flavor, leading to better-quality beer.
Yes, CO2 recovery systems can be scaled to fit the needs of small breweries, offering tailored solutions that integrate seamlessly with their operations.
CO2 recovery significantly reduces a brewery’s carbon footprint by capturing and reusing CO2, contributing to global efforts to combat climate change.
CO2 recovery reduces emissions, helping breweries comply with strict environmental regulations and avoid potential fines or penalties.
Yes, the long-term savings on CO2 purchases, potential tax incentives, and increased customer loyalty make CO2 recovery a sound financial investment.
CO2 recovery isn’t restricted to only benefit breweries and beer production, but can be used in a variety of industries, such as wineries, distilling and helping industrial facilities recover flue gas.
