The next step in building energy efficiency: ElevatorKERS
Skeleton's supercapacitors power ElevatorKERS, a module that captures the energy created by electric traction elevators while an elevator car travels down the shaft and re-uses the energy to lift it. The ElevatorKERS is a simple, efficient, and maintenance-free way to cut down the energy consumption of elevators by more than 50%.

The most important benefits of
using ElevatorKERS

Stand alone system from the main grid

Elevator outages are one of the most common problems that building occupants face. And, while elevator downtime is inevitable, there are ways to minimize the impact. ElevatorKERS helps to keep your building running smoothly and efficiently. There is no regeneration to the grid, meaning there are no harmonic problems.

The elevator will be more efficient

The elevator is a key component of any multi-story building, and its efficiency is crucial to the overall operation of the building. The elevator classification is determined by how much energy it uses in relation to its elevator service life. The higher the efficiency classification, the less energy the elevator uses. Granting an elevator an improved efficiency classification can be a complex process, but it is worth it in terms of energy savings. ElevatorKERS is granting improvement of the efficiency classification of the elevator.

Protect the environment by using less energy

We all know that elevator usage can be a huge energy drain. That's why it's so important to find ways to reduce energy usage and protect the environment. ElevatorKERS is a great way to do just that. In addition, these devices can also help to improve elevator efficiency, meaning that we can save even more energy in the long run. So if you're looking for a way to do your part for the environment, be sure to check out ElevatorKERS. It's a great way to save energy and protect our planet!

Easy installation to any drive

ElevatorKERS is an easy-to-install solution that can be used in new or retrofit projects to significantly increase the energy efficiency of buildings. The two-wire connection simply plugs into any existing elevator drive, making installation quick and easy. By retrofitting elevators with the ElevatorKERS, building owners can save money on energy costs while also reducing their environmental impact. With easy installation and a wide range of potential applications, ElevatorKERS is an ideal solution for increasing the energy efficiency of buildings.

Skeleton Technologies' industry-leading ultracapacitors allow for the recharging of electric traction elevators, cutting down on costly energy consumption by up to 70%.

With the installation of an ElevatorKERS, your electric traction elevator can now take advantage of regenerative driving technology to save energy in addition to reducing its carbon footprint. Unlike other methods that use resistors or batteries for braking purposes, these supercapacitors store up power until needed again during operation which helps reduce reliance on electricity from grids.

The ElevatorKERS is a revolutionary new way to save on energy costs while still utilizing all that clean, renewable power our country has been generating these past few years. By connecting an inverter-powered elevator with this device you can cut down your consumption by as much at 70%
