Atlas Copco’s Beer Foam Separator Increases Production Efficiency


Atlas Copco, a leading brand in the beer industry for air compressors and N2 generator systems, recently introduced a new innovative solution for the beer bottling process – the Beer Foam Separator (BFS 900). Built to be used in combination with its industry 4.0 ready GHS VSD+ screw vacuum pump, the addition of the beer foam separator is primed to improve energy efficiency, reduce lifecycle costs and lower the rejection rate of over and underfilled bottles in the process.


Atlas Copco has launched a beer foam separator with the intelligent GHS VSD+ rotary screw vacuum pump.

The beer foam separator was designed and developed in partnership with leading brewery customers and in direct response to the excess foam production that hampered the beer filling process. The high amount of foam generated at the end of the filling process would enter the vacuum line and disrupt the process, leading to poor quality, reduced output.

Through innovative engineering and rigorous testing, Atlas Copco’s Beer Foam Separator (BFS 900) actively solves the foam issue with its smart features and easy to maintain design – providing full protection to the vacuum pump and saving on costs too.

“Like we always say – we provide not just products, but solutions. Our new beer foam separator is an example of this. Our vacuum pumps and the systems we build contribute significantly to maintaining quality, shelf life and, ultimately, customer satisfaction. This also encourages more trust and reliability for consumers, vital for our valued customers,” said Pamela Cateland, Marketing Manager West at Atlas Copco Vacuum.

The BFS 900 is fabricated from 304 stainless steel for high durability with an auto-draining tank and associated logic control system. When the excess foam enters the vacuum system, it is effectively collapsed in the foam separator by a calming section with a large diameter for foam settling. The rising liquid level is detected by appropriate sensors and an automatic separation process is initiated by an air lock consisting of electro-pneumatic actuators and a receiver tank to enable drain in continuous operation.

The separator is also clean-in-place (CIP) capable. A shower ball mechanism ensures reach to all internal parts, granting compliance to required hygienic standards.

"Addressing process concerns for the beer industry effectivity with our innovative capabilities and application expertise is a focus point for us,” said Alesandro Villa, Applications Manager at Atlas Copco. "That’s why we spent a lot of time perfecting this particular component for the beer industry because we wanted to design a system that would not only protect the pump but would offer a higher level of energy-efficiency and savings for our customers."

The beer foam separator’s effective design delivers several benefits for manufacturers looking to make their beer bottling process more efficient and sustainable. Its prominent features include:

  • No water wastage: In comparison to other technologies, this unique system requires zero water. 
  • Auto-drain function: Control valves are in place to automatically drain, vent and isolate system components. 
  • Durable design: The stainless-steel construction ensures better resistance to corrosion and contamination. 
  • Energy savings: Coupled with GHS VSD+ efficient technology, it delivers up to 40% energy savings versus traditional technologies. 
  • Hassle-free maintenance: The system’s integrated cleaning cycle makes onsite cleaning easier. 
  • Reliable sensors: Level sensors measure beer collected in the drain tank and radar type sensors measure foam level.

High-quality beer, cleaner production floor and sustainable operations – The Atlas Copco beer foam separator effectively tackles the foam issue and provides several benefits for the overall bottling process. Along with the intelligent features of GHS VSD+, it’s a solution that brings a new level of efficiency for the beer industry.
