BE CO2 SELF-SUFFICIENT
CO2 Recovery Unit (CRU) is a robust and reliable CO2 recovery solution for a wide variety of brewery needs ranging from 300,000 to beyond 5,000,000 hl/yr. It is the benchmark CO2 recovery plant in the global brewing industry with 25-year-old plants still running strongly.
The CRU-program comes with a range of options from cost-effective conventional CO2 recovery plants to plants incorporating the latest technologies. Each CRU plant is an individual jewel: We listen carefully to your needs and design (y)our CRU to your specific requirements. Not much space available for a new plant or retrofit: No worries, our engineers will find a solution for the most restricted space conditions.
The purity of the liquid CO2 end product exceeds general quality standards for food/beverage/ingredient purposes including the latest edition of the ISBT standard. Recovering your own CO2 lowers your site’s CO2 footprint and reduces your VOC emissions to the atmosphere. Both contribute to a more sustainable operation.
Worldwide, customer-specific solutions will be installed and commissioned by a team of experienced and well-trained service engineers. But the dedication to your CO2 self-sufficiency continues after the commissioning. Through comprehensive lifecycle management, our technical support and service team ensures that your CRU operates optimally.

- Robust design for reliable 24/7 operation, uptime ≥ 95%
- Flexible, modular setup to meet site’s layout needs
- Natural refrigerants CO2 (R744) and NH3 (R717) applied
- Early recovery and up to 60 % energy savings with LiquiVap (optional)
- Access to CO2 knowhow and technical support
PROCESS DESCRIPTION
Raw foam-free fermentation gas is fed to the plant where it is buffered in a balloon (1) and scrubbed of water-soluble contaminants such as ethanol in the gas washer (2). A 2-stage dry running CO2 compressor unit (3) increases the gas pressure to 18barg (261psig) removing condensate in the process. The remainder of the impurities and water are then removed in the dual activated carbon filter and drier unit (4). Regeneration of this unit is automatic utilizing heating elements and dry CO22 purge gas. CO2 liquefaction takes place in a refrigerant cooled condenser (6) which includes refrigerant condenser (7) and refrigerant compressor (8). O2 is removed in the stripper (5). The purified liquid CO2 end product is transferred to the onsite storage tank.

For breweries wanting to take a strategic step towards self-sufficiency with CO2 Recovery, harvesting and collection technology is needed to bring the CO2 from the fermentation area to the CO2 recovery system. This technology also helps to mitigate the release of excess CO2 into the atmosphere during fermentation by capturing it at its source for CO2 recovery.
