This motion technology delivers supreme opening ease with a single touch. Ideal for handless furniture featuring lift systems, pull-outs and fridge/freezers which then will seem to open by themselves. They then close again with soft-close BLUMOTION. Depending on your layout, one or two power supply sets may be all you need to power your entire kitchen! Don't worry, if there’s ever a power outage, drawers and lift systems equipped with SERVO-DRIVE can easily be opened by hand.
