New valve technology can revolutionize Carlsberg´s beer production

A new water-controlled hydraulic seat valve has demonstrated significant benefits in brewing tests. Danish company HYDRACT is ready to bring patented valve technology to market.

The European Union is co-funding the H2020 HYDRACTFLEX project with €1,85 m.
The Hydract process valve, developed by the Danish company HYDRACT has impressed Carlsberg with its precision and repeatability in addition to a 90% reduction in electrical power consumption.

In Fredericia, Denmark, tests aiming to demonstrate Carlsberg’s Smart-Mix concept by using on/off mix-proof valves equipped with Hydract actuator technology as high precision regulating valves has demonstrated that beer can be blended On-Demand and Just-In-Time. Other positive effects in addition to electrical power reduction include reduced water consumption, cleaning chemicals and a reduction in capital investments for green and brown field installations.

”Our tests of the HYDRACT-valve have exceeded our expectations. The precision and repeatability achieved with water hydraulics as an alternative to compressed air enables an entirely new approach to effective and sustainable beer production. It fundamentally changes the way we can produce beer in the future,” says Anders Kokholm, Brewing Director at Carlsberg Supply Company DK.

Developed since 2008 and in production at Carlsberg since 2016
Over the past 10 years, Carlsberg has been closely involved in developing and testing the Hydract actuator, and since 2016 Carlsberg has implemented the Hydract actuator both with new Hydract valves and as retrofit to existing valves, at the company’s brewery in Fredericia, Denmark.

“Because water is incompressible, our hydraulic actuator provides a vastly improved level of precision and control compared to pneumatic actuators. HYDRACT enables customers to reconsider the production methods and processes they use, due to the stability and precision of the Hydract actuator” states Peter Espersen, founder and CEO of Hydract.

Funded by the European Union
The EU-funded H2020 demonstration project HYDRACTFLEX involves a consortium of European companies, each of whom are contributing with knowhow and experience.

  • Carlsberg - brewing expertise
  • Hydract - water hydraulic process valves
  • ProLeiT - control software
  • ACM - laser refractometer technology

The HYDRACTFLEX project is aiming to demonstrate Carlsberg’s Smart-Mix concept in full scale.
