Knowsley Lift Services offer a complete solution in terms of pre- survey, supply and installation of a small and compact energy saving and transferable unit which can be added to new or existing traction lifts with a VF drive. The unit works by harnessing energy normally lost as heat or noise as the lift slows down. Our unit stores the energy created and all recovered energy is 100% recouped directly back into the lift from which it came ensuring the lift can then re-use this normally lost energy to run as opposed to drawing all the energy again from the power grid.
