The energy costs for a Montech conveyor with conventional drive are 1.500 EUR per year at a transported weight of 120 kg in a 3-shift operation. The conveyor TB40 (with integrated drive into the drive roller) needs only 500 EUR for energy costs.

So users can save energy costs of 1.000 EUR per year.
