This remarkable elevator hoisting machine based on permanent magnet synchronous motor is not only a major technical innovation, but also a significant contribution towards sustainable development.

EcoDisc powered KONE elevators offer superior customer value, including space savings, lower construction costs and dramatically reduced use of energy-ideal choice for modern, environmentally sound buildings.

Energy Efficient
The EcoDisc uses upto 60% less power needed by comparable conventational systems. High efficiency eliminates the need for cooling and air conditioning.

Environmentally safe
The EcoDisc uses no oil, removing the contamination and fire risks always present in hydraulic systems.

Super Compact
The disc like Eco-Disc weighs only half of conventional equivalents. The compact shape inspired the world's first real machine-room-less-elevator-KONE Monospace.

Velvet - smooth ride
Elevators powered by the EcoDisc run smoothly and quietly. Just one moving part, slow revs and gearless construction guarantee reliable operation for decades to come.
