ENERGY RECOVERY
FOR ELEVATORS

Kinetic Energy Recovery System (KERS) - up to 70% energy savings & elevator efficiency improvement

Benefits of our solution

  • Up to 70% energy savings
  • Improvement of the efficiency class of the lift
  • Simple two-wire connection to any drive, new or existing
  • Maintenance free – 24 /7 /365 system

Challenge

Energy wasted in braking resistors & high energy consumption

  • Background
  • Elevators are counterweighted based on the average load
  • Lowering or empty lifting means waste of great amounts of mechanical energy through braking resistors
  • Highly cyclic operation, sometimes thousands of trips/day for one elevator
  • key challenges
  • Waste of energy in braking resistor
  • Energy efficiency is becoming more and more a key focus point of many economies
  • known consequences
  • High energy costs, as power is dissipated at each trip
  • High peak power absorption results in power quality issues and high cost
  • Low elevator efficiency, driving down building overall efficiency class
