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.
This innovative door system combines the latest technology with precision-engineered noise reduction techniques to deliver one of the fastest, quietest door systems in the industry.
Some installations show as much as a 46 percent improvement in door-opening performance - from 3.0 second to 1.6 seconds.
Closed-loop control compensates for variations that may cause doors to operate inconsistently
The Otis closed-loop system self-corrects and adjusts, so wind and temperature changes or even minor debris won't hamper the doors.
Less moving parts means fewer repairs, saving you downtime and money
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.
