PWM control system
By adopting a PWM
(pulse width modulation)
control system that is close to a sine wave,
noise and vibration are reduced
to provide a comfortable ride.

Economical elevator replacement time
| Construction Classification | Replacement time considering economic feasibility | Replacement work history |
|---|---|---|
| Design replacement work | 7 years after installation |
To create a cozy and sophisticated space, we replaced the elevator ceiling,
wall door and signal device. A construction to replace the dark and untidy atmosphere with a new, elegant design. |
| Model replacement work | 10 years after installation |
To reduce electricity bills and improve riding comfort according to the operation of the elevator,
replace it with a new model or Construction of replacing the control method with a new technology (*The electricity cost of the new technology is reduced by about 40% compared to the previous technology) |
| Demolition and replacement work | 15 years after installation |
Each part of the elevator deteriorates due to long-term use,
resulting in a surge in repair costs and lower reliability of safety. Complete replacement of elevators with reliable elevators by increasing the efficiency and safety of the elevator |
