Green Elevator
1. Motor Room Less
Our lifts incorporate machines room-less system, it allowed in designing a lower overhead for space saving, cost saving during construction and enhance architecture aesthetics. It also consumes less power thus more cost saving.
2. New Regenerative Energy-Saving Device
Regenerative Energy-Saving Device is an energy saving device to replace the usage of braking resistor with the features that could bring the advantage include:
- Advance IGBT & phase amplitude control PWM calculation method is used
- Improve declaration performance by inverter
- Motor to generate surplus electrical energy during lift deceleration (in generating back the energy to inverter)
- Lift system is operating by the regenerated energy for energy saving
- Inverter would have sufficient deceleration without using braking resistor
- 95% and above of regenerated electrical energy can be reused
- Regenerative energy is low harmonic energy with comply IEC61000-3-2 & GB/T14549
- Low noise sound created at the capacity of <60dB
- Component made by ROHS standard
In comparing to the traditional method usage of braking resistor for regenerating energy consumption during deceleration period in elevator, it is not only a waste of energy as well as the decrease of its operations efficiency, but also the heat would generate by the braking resistor that could warm up the environment.

3. Permanent Magnet Gearless Synchronizes Motor
EITA High Speed Elevator is driven with a permanent-magnet gearless synchronous motor. Its large torgue outputs at low revolutions resulted in smooth and low noise operation of the elevator. The high efficiency and power factor enable energy saving of up to 30% – 40% as compared to conventional warm geared machin
