Innovative Solutions for Energy Efficiency in New Generation Escalators
New generation escalator systems that optimize energy efficiency with innovative technologies both increase performance and provide long-term savings. Manufacturer company officials summarize the improvements made for energy savings as follows:
Technological Improvements:
- LED Lighting Systems: Longer lasting and more economical than traditional lighting.
-Operation System Modes: Energy consumption is optimized with modes such as Run-Stop, Run-Slow, Run-Slow-Stop.
- High Efficiency Motors: OMS brand motors, which provide over 95% efficiency, offer energy savings of up to 40%.
-VVVF Drives and Radar Systems: When no passenger is detected, the system minimizes energy consumption by reducing the speed to 0.10 m/s; when the passenger approaches, the staircase restarts and reaches high speed.
-Regenerative Inverter Technology: Energy is recovered by using the generator effect of the motor during stair ascent and descent.
Impact of Maintenance on Energy Efficiency:
Officials emphasize the critical role of planned periodic maintenance of escalators in energy savings. It is stated that by recommending predictive/ preventive maintenance methods for systems with intensive use, operational costs will be reduced and system life will be extended.
Smart Energy Management:
Escalators optimize energy consumption by switching to standby or sleep mode thanks to PLC software. They can also be integrated with smart building systems to share data on building energy management.
Energy Storage Systems:
Work continues on regenerative energy technologies to optimize energy consumption during peak usage hours. However, it is emphasized that the initial investment costs should be evaluated in detail.
Maintenance-Free Step Chains:
By using maintenance-free step chains that are resistant to external influences, wear and friction problems are reduced, energy savings are achieved and the life of the system is extended.
Company officials state that increasing energy efficiency in escalators is possible not only with component selection but also with the right usage methods. "With smart control systems and energy-efficient components, we provide major energy improvements in escalators. As a sector, we are undertaking an important role in increasing conscious use,” they say, emphasizing the importance of smart energy solutions for the future.
