This case study shows the implementation of an Energy Recovery System in a high-traffic elevator on a cruise ship.
The elevators installed on ships must adapt to extreme conditions that are not very friendly for elevators: humidity, sea salt, and constant movement. Furthermore, safety and energy efficiency are also crucial.
The elevator specs are:
- Elevator: Schindler.
- Distance/stops: 7 stops.
- Weight/load: 600 kg.
- VVVF drive: Variodyn VF33 BR.
ERS 2G. An efficient and easy-to-install solution for recovering energy from your elevator.
It was chosen to implement the Energy Recovery System for lifts (ERS 2G), equipped with supercapacitors to recover and store the energy wasted during braking.
This energy, once stored, is reused in short trips that generates consumption, to reduce the elevator’s energy demand.
This solution enabled a 34% reduction in motor energy consumption.
Benefits of installing an Energy Recovery System for Lifts (ERS 2G).
- Fast and easy installation: It was installed in less than one hour.
- Maximum compatibility: It works perfectly with any VVVF drive and fits existing elevators.
- Energy efficiency: It reduces the energy consumption and improves peak management.
- Minimum maintenance: The system is robust and requires not maintenance, making it ideal for the marine environment.
The implementation of the ERS 2G system has not only improved energy efficiency but also enabled more reliable and sustainable elevator.
