ThyssenKrupp Elevator Korea has announced that three of its elevator flagships, the GL1, Evolution1 and Elejet, have been awarded VDI 4707 certification class A by TÜV SÜD, an internationally recognized German certification body.

VDI 4707 is an elevator energy efficiency evaluation and management system developed by the Verein Deutscher Ingenieure (German Association of Engineers) and is a Europe-wide guideline that categorizes elevators into seven classes, from A to G, based on their operating hours, energy use during operation, and average distance traveled. The guidelines introduce energy-efficient design for elevators to reduce their environmental impact.

ThyssenKrupp Elevator Korea's energy efficiency tests for the GL1, a low- to medium-speed gearless elevator, the Elejet, a high-speed gearless elevator, and the Evolution1, a machine room-less elevator, resulted in all three products receiving the highest grade of A, officially recognizing their eco-friendly technology.

In line with society's demand for green management and the ThyssenKrupp Group's 'Sustainable Efficiency' program, ThyssenKrupp Elevator Korea prepared for the VDI 4707 certification assessment since February this year, and succeeded in obtaining the certification in July after a rigorous evaluation at the Cheonan factory test tower on May 19th.

ThyssenKrupp Elevator Korea's products were found to be able to significantly reduce energy consumption, with both standby and operating power consumption below the standard, especially in standby mode, which was rated as the highest in Korea.

The products automatically shut down fans, lamps, indicators, etc. during standby to cut off unnecessary power, and as a result, they earned an A rating for standby power consumption, which means the highest efficiency. They also received the highest grade of A for power consumption during operation, thanks to the eco-friendly technology of the CPIK-R, a power-recovery inverter.

"Our A-rated products generate electricity from the movement of the elevator and can be used for other purposes in the building, reducing energy consumption by up to 50-60%," said Kwan-Cheol Yoon, head of the Engineering Center.

In January, Synergy, the company's machine room-less elevator, was also awarded an energy efficiency class A in the VDI 4707 certification by TÜV SÜD. Under the group-wide Sustainable Efficiency program, ThyssenKrupp Elevator is making systematic and ongoing efforts to reduce energy and CO2, from material selection to installation, service and recycling.
