ESCALATORS GO ECO-EFFICIENT
KONE is the first in the industry to offer an eco-efficient escalator, which combines a highly-efficient drive system with a compact drive to achieve new levels inenergy-efficiency, space saving, reliability and aesthetics. A KONE escalator can also save energy when there are no passengers on board. By using standby speed and energy-efficient LED lights, you can cut theescalator’s energy consumption considerably. Many of the solutions described here are available as easy to install retrofit packages.

1. MECHANICAL SYSTEMS ECO DRIVE
• Highly-efficient planetary gearwith spur gear for direct connections to main shaft and handrail drive shaft • Extended oil change interval of 30,000 hours (almost twice as long as for a conventional drive system) • Applicable forKONE EcoMaster escalators • Efficiency of 96% (conventional gear 87%) • Energy savings: 950 kWh/year* • Carbon footprint reduction: 460 kg CO2/year**

LUBRICATION FREE STEP CHAIN
• Permanent greasedand sealed chain links do not require extra lubrication with oil • No oil consumption, the truss stays oil-free • Reduced wear of chain links and bushings • Reduced fire risk • Average oil savings: –Commercial escalator: 1-2 litres/month – Transit escalator: 5 litres/month

2. ENERGY MANAGEMENT STAR-DELTA ENERGY SAVING
• A conventional energy saving feature as basic option • When there is lowescalator traffic the motor is switched to star operation and supplied with lower voltage. When several passengers enter the escalator the motor is switched back to delta operation. • Recommended for lowload situations • Energy saving: up to 25% depending on passenger load, motor and drive, 1400 kWh/year* • Carbon footprint reduction: 680 kg CO2/year**

POWER FEEDBACK UNITS
• Feedback ofregenerated power to mains provided from braking or downward running of passenger loaded escalator • Replaces brake resistors, which generate heat • Technology for extensively used escalators • Energy...
