Pushing efficiency beyond its limits

Energy-saving covers minimize elastic deformation at idler rollers — reducing rolling resistance, energy loss and drive power cost. Only the bottom cover compound is modified, so it applies to existing lines with no structural change.

24–29% power savings Verified by ITA, Germany Patented · Green Tech certified

How It Works

①Less internal heat generation from deformation

②Minimized kinetic-to-thermal energy conversion

③Minimized energy loss to heat → power saving

Patent & Green Technology

Patent No. 10-1900663 (energy-saving belt with natural rubber + neodymium butadiene rubber); Green Technology Certification acquired in 2019. No loss in belt lifespan while cutting drive power.

Verified by ITA, Germany

Approx. 24–29% power savings achievable, based on DIN 22123 indentation rolling resistance testing (verified March 8, 2016). Actual savings vary with line conditions and operating environment.
