Sustainable. Responsible. Enviable.
What does an empty elevator going up have in common with a full elevator going down? An abundance of excess energy. Electrical power is generated when a heavily-loaded car travels in a ‘down’ direction or a lightly-loaded car travels in an ‘up’ direction.
Elevators with conventional non-regenerative drives waste the generated energy as it is dissipated in a set of resistors.
ReGen drives, featured in Gen2 elevators, convert this excess energy into electricity and feed this captured power back into the building’s electric grid for reuse by other building systems such as lighting. ReGen drives deliver substantial energy savings while meeting or exceeding established worldwide standards.
- Up to 75% energy savings as compared to conventional systems
- Produce clean power that minimizes impact on the building’s electrical system due to low harmonic distortion (typically below 5%)
- Operational cost savings through reduced peak power demand and decreased energy consumption
- Optimal performance — the drive operates with voltage fluctuations of up to 30 percent
Reduced energy consumption
Gen2 system with ReGen drive reduces energy consumption by 75% under normal operating conditions
