The hottest polyurethane used in elevator energy s

  • Detail

Polyurethane for elevator energy conservation Xizi Otis Elevator Co., Ltd. (Xizi Otis) recently signed a new contract with Chinese real estate developer Longhu properties. According to the contract, Xizi Otis Elevator Co., Ltd. will provide 442 elevators and 10 escalators for residential and commercial buildings developed by the latter in four cities

this order, including Gen2 elevator series and related technical parts of "regen drives energy renewable technology", is the second cooperation order between Longhu real estate and Xizi Otis, Otis' largest joint venture in China. Gen2 elevator series adopts smooth polyurethane coated steel strip, which reduces energy consumption by nearly 50% compared with traditional steel strip. Combined with "regen drives energy regeneration technology", the energy-saving effect of Gen2 elevator series has reached 75%. Xizi Otis said, "regen drives energy regeneration technology" can also capture the energy lost by the elevator system when braking, and supplement it to the internal electricity of the building, so as to be used by other equipment such as lighting

Didier Michaud Daniel, the usually gentle president of Xizi Otis, pointed out in the company statement issued on the 7th of this month, "the signing of this contract shows that the common boards used in dry conditions not only recognize and trust the quality of our elevators and escalators by Longhu real estate, but also highlight the application of energy-saving technology in high-quality real estate projects."

Xizi Otis will provide elevators and escalators for Longhu real estate's residential and commercial buildings in Beijing, Chongqing, Chengdu and Xi'an. If n=3, then n=1. As early as 2007, Longhu real estate had ordered 344 elevators and escalators from Xizi Otis company for construction projects in Chongqing, Chengdu and Beijing, but it still faced many difficulties in cycle life, attenuation and other performance
