Lift inverters achieve higher efficiency levels
Gefran's new and exclusively designed ADL and AVRy lift drive inverters cover entry-level to advanced performance for power ranges up to 90kW with a strong emphasis on energy efficiency and application versatility. Designed with over 40 years of experience in civil lift engineering, the new drives offer reduced energy consumption and reduced CO2 emissions across the range with regenerative 'clean energy' power recovery technology available with the AVRy versions.
When compared to other lift drive designs, the ADL series can increase system speed and reduce energy consumption and costs by up to 48% as well as reduce CO2 emissions by up to 1000kg/year. AVRy regenerative drives can further reduce energy consumption by an additional 42%, for total savings of up to 90%, with CO2 emissions reduction up to 6000kg/year.
The ADL100 series features an advanced sensorless vector control to provide a cost effective solution for geared lift applications with speeds to 1.2 m/sec and use with asynchronous induction motors. The modular design includes a simplified I/O configuration but includes full featured lift control capability with integrated braking control and wireless remote interfacing for Bluetooth devices. An integrated RS232 serial communications port is also included with Modbus RTU protocol and set-up/diagnostics made easy with a PC programming wizard or an optional multilingual keypad. All Gefran lift drives are built for maximum lift cabin operational flexibility and extreme levels of comfort for lift passengers.
