Closed-loop door operator

Consistent, smooth door operation

The Otis closed-loop door operator constantly monitors the speed and position of the elevator doors, and compares this data to pre-defined opening and closing profiles.

It works like a car’s cruise control — you set a particular speed and it adjusts the gas to ensure the car travels at the desired speed.

Peace Of Mind Icon

Peace of mind

Less moving parts means fewer repairs, saving you downtime and money

Environmentally friendly

This door system uses electronic communication and a permanent magnet motor which eliminates the carbon-brush dust found in traditional DC systems. In addition, the permanent magnet motor is more energy efficient than operators that use induction motors.

Furthermore, the systems sealed-for-life bearings do not require any lubrication making it cleaner for your elevator and the environment.
