Knauf Integral KG has been eager to optimize and raise energy-efficiency potentials in its 12-level gypsum dryer. They primarily used DOL motors running 24/7 at full and partial load.

Knauf Integral KG is an independent company within the Knauf Group. At headquarters in Satteldorf they use a unique production method to manufacture the high density gypsum fibre drywalling material GIFAtec. The level of energy efficiencyin its 12-level gypsum dryer has been increased by the use of a synchronous reluctance drive system from Siemens.

• Highly efficient variable-speed operation with SIMOTICS synchronous reluctance motor and SINAMICS G120 converter
• The Siemens solution was the more efficient drive system compared to another system tested.
• In addition, the new engine was compatible with the previously used engines, which meant that no investment in a replacement kit was required.
