The new generation of efficiency. This is the message that Gefran (Italy) launches at Interlift 2009, the top international event for the civil lifting market. A message that synthesises the main features of its new range of drives, designed to save energy and protect the environment.

Thanks to Gefran’s know-how from over 40 years in civil lifting, the new range is based on technology that ensures greater plant efficiency by recovering and regenerating energy for the grid, thereby achieving significant energy savings.

These new series of drives (ADL200, ADL100 and AVRy) are the result of an analysis of real needs of operators and of constant technical and practical cooperation with system integrators and builders of lift systems.
These are versatile, modular solutions that adapt to every type of system - roomless or traditional, with or without gear motor – and offer ad hoc control configuration for all types of automation architectures.

The ADL200 and ADL100 drives are available in a wide range of power levels and integrate specific advanced functions for the lift sector. These functions ensure high performance and make starting and stopping of the cabin extremely comfortable, precise, and safe in systems with asynchronous and synchronous drives and with the advanced configurations of modern civil lift systems.

The AVRy drives integrate state-of-the-art control for synchronous motors and sophisticated technology to recover “clean energy” for the grid. They exploit the energy potential generated by vertical movement of the cabin mass and convert it into electrical energy to be regenerated to the power supply.

Each drive offers significant benefits:
ADL drives increase system speed and reduce energy consumption and costs by up to 48%. With regard to environmental impact, ADL drives cut CO2 emissions by up to 1000 Kg/year.

These values are further increased when regenerative AVRy drives are installed. In this case, energy consumption is reduced by an additional 42%, for savings of up to 90%, while CO2 emissions are reduced by up to 6000 Kg/year.

With an advantageous motor-drive size in combination with the new range of high-performance TSM300H drives, AVRy offers significant benefits in terms of running costs.
