Brewery more than doubles filling capacity with VLT® FlexConcept®

07 June 2012
By installing a new KEG filling line using VLT® OneGearDrive® geared motors, frequency converters from the VLT® AutomationDrive series, and VLT® Decentral Drives, Rothaus AG has increased its filling capacity from 120 to 280 KEGs per hour with fewer drive types, and without increasing overall energy consumption.

Project manager Ralf Krieger and Filling Manager Roger Jäger from Rothaus AG, aided by their teams, selected Danfoss products for the drive systems of the new plant.

“We have used Danfoss frequency converters with success for several years and knew there was a potential to reduce the number of drive types in our production. The VLT® FlexConcept® also helps us to reduce our spare parts inventory,” explains Ralf Krieger, who also took the opportunity to start testing Danfoss VLT® OneGearDrive®.

Designed for efficiency

“The components used in the VLT® FlexConcept® have proven their worth in the plant up to now. All motors and frequency converters operate reliably, and their designs offer a number of benefits compared to conventional drives. The equipment may optionally be operated in a centralised, decentralised or combined structure. All drives are designed for extremely high energy efficiency and provide good starting point for us to consider other projects with Danfoss products,” concludes Ralf Krieger.
