Apatin Brewery: Saving electricity by implementing Danfoss VLT® FlexConcept®


  • Client need to reduce production and maintenance costs
  • Increasing the required maintenance budget from year to year
  • Increasing the number and timing of unplanned downtimes
  • Finding more and more expensive spare parts and quality technical support
  • Increasing the number and duration of unplanned downtimes


  • Replacing existing gear motors with a more modern and efficient solution (Danfoss One Gear Drive)
  • Installation of new frequency regulators (Danfoss FC302) adapted to work with new motor reducers
  • Replacement of existing power cables
  • PLC software modification
  • Parameterization of frequency regulators and commissioning of lines


  • Large electricity savings (32% -38%)
  • Short return on investment (3 years)
  • Long device life
  • Reduction of inventory costs (only 3 possible variants of gear motor)
  • Washable construction
  • VLT® OneGearDrive® can be cleaned quickly and easily, saving the brewery time and water and detergent costs.
  • VLT® OneGearDrive® is ideal for the food and beverage industries, as it complies with the high hygiene standards required.
  • VLT® OneGearDrive® is mounted directly on the conveyor shaft, which is an advantage in retrofit projects.
  • With the VLT® OneGearDrive®, the oil change is required only once every 35,000 hours of operation, thus reducing preventive maintenance costs.
  • VLT® OneGearDrive® and VLT® FlexConcept® provide maximum flexibility with a minimum of variation in gear ratios and frequency regulator power, reducing inventory costs by up to 70%.
