Eco-efficient solutions from Kone Elevators

Supplier News

The power behind eco-efficient solutions is the Kone Elevators EcoDisc hoisting machine, which can save half or more of the energy consumed by an elevator. Kone solutions not only save energy when the elevator is moving, but also provide solutions that reduce standby energy consumption when the elevator is standing still. Working together, these solutions can save as much as three quarters of the elevator’s total energy consumption. Over the lifetime of the equipment, the energy savings can amount to more than the original cost of the elevator.

The Eco efficient solutions are made up of the following elements:

The EcoDisc Hoisting machine, which includes the following features:

  • Consumes 70% less energy than a hydraulic drive and50% less than a traction drive
  • Permanent magnet synchronous hoisting machine
  • Due to variable frequency drives used in our solutions, the peak starting current is 30–40% of that of equivalent hydraulic and traction units, reducing energy consumption and size of fuses
  • Thin and lightweight, requires less raw material and space compared to traditional hoisting machines
  • Energy saving: 4000 kWh/year compared to hydraulic elevator, 2000 kWh/year compared to traction 2-speed elevator
  • Carbon footprint reduction (based on OECD electrical energy mix): 2240 kg CO2/year compared to hydraulic elevator and 1120 kg CO2/year compared to traction 2-speed elevator
Halogen free cables, which offer the following features:
  • In case of fire they do not produce toxic gas and do not release corrosive acids
  • Plastics used in cables for electrification do not contain halogens
The Regenerative System includes:
  • Can recover up to 25% of the total energy used by an elevator
  • Recovers excess braking energy from the elevator and converts it for use e.g. in lighting the building
  • The counterweight or elevator car becomes the motor and KONE EcoDisc becomes a generator and converts the power into current
  • Produces clean and safe energy that does not damage the network
  • Energy saving: 13,250 kWh/year compared to a non-regenerative drive
  • Carbon footprint reduction: 6400 kg CO2/year compared to a non-regenerative drive
