Elevator modernization by utilization of excess gravitational potential energy


Components of elevator system, depending on the situation, have excess gravitational potential energy that goes to waste. Our solution stores and utilizes this energy by hydraulic kinetic energy recovery system- KERS. This way, overall elevator electricity consumption is decreased by 10%. Not much per elevator, but there’re 80000 new elevator units each year so savings sum up significantly
