Green Energy Recovery Lifts

Premium Grade European Standard Lifetime Support

Experience unparalleled quality and innovation in elevator technology, designed for discerning clients who demand excellence in every detail.

Regenerative Drive Engineering

Green energy recovery lifts utilize a regenerative converter to turn mechanical energy into electrical energy. In a traditional lift, when a heavy car travels down or a light car travels up, the excess potential energy is dissipated as heat through a braking resistor. A regenerative drive captures this energy, filters it for harmonic distortion, and feeds it back into the building’s power grid to be used by other appliances. This technical process effectively turns the elevator into a small power plant during specific phases of its duty cycle. The system includes an AC/DC/AC converter that synchronizes the frequency and phase of the recovered energy with the main supply, ensuring high power quality and reducing the building's overall electricity consumption by up to 30% in high-usage environments.
