Energy Recovery System ERS
Take advantage of all the energy generated by the elevator during braking and save up to 64.8% on electricity.
The Energy Recovery System ERS stores the energy generated by the elevator during braking, reusing it for future trips to reduce consumption peaks.

What It Does
Harnesses the energy generated by the elevator for energy savings of up to 64.8%*
Significantly reduces consumption by capturing and storing the energy wasted when the elevator motor brakes, using supercapacitors. This stored energy is then reused in subsequent trips or during peak consumption periods.
The ERS Energy Recovery System can be easily connected to any elevator, whether new or existing, and requires no maintenance.
*Percentage based on measurements conducted by Epic Power.

- High-demand product in the market
- Guaranteed improvement in the elevator’s energy efficiency rating
- Easy installation via two cables to any drive
- Compatible with both new and existing elevators
- Significant increase in energy efficiency and reduction in electricity consumption
- Integrated storage system with ultracapacitors
- No energy feedback to the grid (avoids noise and harmonic distortion issues)
- Ability to connect multiple units in parallel
- Very low standby consumption, almost zero
- Long lifespan, even exceeding that of the drive itself
- Stores energy instead of returning it to the grid, ensuring network stability
How It Works
Energy Recovery System with Integrated Storage
- Stores the energy wasted during elevator braking and reuses it for the next trip
- No harmonic distortions and no added standby consumption
- The system can be easily connected to any new or existing drive, regardless of the brand.
