Fast Commercial Passenger Lift / Passenger Elevator

Brief introduction:

DNDT traction passenger elevator applies multiple drive modes. It matches with multiple safety protection devices to ensure the secure running. Commercial passenger elevator uses VVVF technology with smooth speed adjustment, smooth and comfortable travel. It suits the requirement from modern high-rises.

It is safe and comfortable with the sound energy-saving and environment-protection. It creat a brand-new elevator space by humane design concept.

Communication technology
Advantages of DNDT commercial passenger elevator:

It adopts the network communication, which greatly reduces quantities of the wires, which brings about enhancement of reliability and reduction of the installation period.

Anti-interference

DNDT traction passenger elevator with its control system fully comply with the relevant electro-magnetic compatibility standards. It can effectively gets rid of the electro-magnetic pollution and grants you live and work in peace and content.
