GRPN20 machine roomless passenger lift
 
We know very well about the loss reduction and energy-saving, environmental protection ideas for GRPN20 machine roomless passenger lift.With great improving on design freedom of motion & full expressing on green humanities, we endeavor to save the building area,enhance the freedom in design,fully display a green and human concept.Compared with same loading level geared lift, it can save 25% of the electricity 10% of the building area. GRPN20 machine roomless passenger lift breaks through the premise that every lift needs to have a machine room.It offers an infinitely inventive possibility for the limited space in the modern constructions.
 
Permanent magnet synchronous gearless traction machine
We choose rare earth material and fully combine coaxial transmission technology and digital variable frequency technology with group computer combined control technology.With less running cost & less energy dissipated.Compared with the ordinary and traditional technology,gearless traction machine can save more than 30% of the energy.Gearless traction machine needs no renewal of lubricant.Without grease pollution,low noise,quiet & natural.
 
Energy-regenerating technology
From technically fulfilling  energy-saving to energy-generating revolution,energy feed-back technology represents another significant breakthrough of the elevator technology.It compensates a leak of which regular elevator consumes the electric energy of the motor by energy resistanc.It effectively feeds back the regenerative electric energy of resistance.It effectively feeds back the regenerative electric energy of the motor to AC electric grid.It supplies other surrounding power equipments.Single item can save as high as 30% of the electric energy.
 
Automatic lighting of LED energy-saving lamp
We use energy-saving LED lamp.When nobody uses the lift.The lighting in the car will turn off automatically & automatically turn on once receiving any calling commands.Saving the electrictly energy consumption sufficiently.
 
Voice reporting
Under normal running arrival,report the floor that is about to arrive by utilizing the voice device; before lift door closing,voice device will forecast next running floor,making the movement harmonious and natural.
 
Low noise
Offer a quiet space for you
 
Top advanced door operator system
Applies the advanced VVVF variable voltage and variable frequency control technology to the lift door operator system so as to ensure the smooth lift door and quiet switch.What is more,the self-learning door load detetor increases the sensitivity of te lift door switching on/off.It monitors the variation of lift door load on every floor.It automatically rectifies the most appropriate open/shut speed in every floor so as to guarantee the security and reliability.
