Spotlight on Innovation: OTIS GeN2 Switch Technology

In 2014 Otis released the Switch elevator powered by patented GeN2 technology. The machine is pioneering in terms of its energy efficiency and ease of installation. Its highly efficient and compact qualities make the GeN2 Switch best suited for use in residential buildings, especially those that were built without an elevator.

How does the GeN2 technology work?

The GeN2 uses flat polyurethane-coated steel belts instead of the traditional steel ropes. They are 20% lighter and last three times longer than traditional ropes. The polyurethane-coat finish also serves to make the belts more flexible, which allows them to bend tightly around small diameter sheaves. This superior flexibility allows for a more compact gearless system that is 50% more energy efficient than a conventional machine.

What are the benefits of the GeN2 Switch elevators?

One of the clearest benefits of this machine is its energy efficiency. The GeN2 Switch elevator uses an electronic-battery pack to power the machine, the battery pack is charged by energy generated by the elevator when it is in use. When the motor is idle, the electronic -battery pack recharges and prepares to power the motor when it next comes into operation. This system produces significant savings to electricity bills. The electronic-battery pack also enables the elevator to continue in service in the event of a power failure, the elevator can make up to 100 trips after the power has failed.

The elevator has less movable parts than a conventional machine and provides a very comfortable ride for its passengers. The gearless system means there is minimal noise when the elevator is being operated. This benefit, combined with the fact that the GeN2 requires no specific electrical installation, makes it a great passenger lift system for residential buildings. The compact machine can be plugged in like any other electrical appliance in the building using a single-phase 220V power supply; making installation easy and affordable.

Compared with other conventional systems, the GeN2 also ranks highly in terms of environmental protection standards. The polyurethane-coated steel belts remove the need to lubricate the machine’s parts, thus avoiding the need for hazardous wastes.
