Door Operators

Glide A Door Operator - Our Most Current Door Operator

SWIFT, QUIET OPERATION The Otis Glide A door operator is one of the most reliable door systems in the world. With door open times as fast as 1. seconds with 42” center opening doors, the system allows passengers to enter and exit elevators more quickly for faster floor to floor travel times.

RELIABLE PERFORMANCE The Otis Glide A door system significantly reduces the number of moving parts. It uses direct drive belt technology, eliminating linkages and cam mechanisms to minimize the chance that an issue will arise. The system’s high resolution encoder provides exact position data to the closed loop software in order to achieve consistent performance in variable environmental conditions such as wind, temperature and humidity extremes.

ENVIRONMENTALLY FRIENDLY The Otis Glide A 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 system’s sealed for life bearings do not require any lubrication making it cleaner for your elevator and the environment.
