This marked the successful completion of the overall equity restructuring project for Shanghai Sanden Behr Automotive Air Conditioning Co., Ltd., laying a solid foundation for the company's sustainable development in future.

In 2001, to align with the global trend of lightweight automotive air-conditioning compressors, the company independently developed the ultra-lightweight fixed displacement compressor—BX. By optimizing its structure and material applications, this product significantly reduces the compressor's size and weight while enhancing operational reliability.

To seize the strategic opportunity in future automotive technology and closely follow the new trends of the overall automotive industry development, the company commenced the R&D of electric scroll compressors in 2000. These compressors feature independent driving capability, as well as superior control, energy efficiency, environmental friendliness, and comfort.

On June 21st of the same year, the joint venture signing ceremony for Sanden (Shanghai) Automotive Air-Conditioning Co., Ltd. was held. This marked the company's first comprehensive collaboration with a world-class automotive air conditioning supplier through joint venture cooperation in technology, production, and sales.

In 1997, the company signed a technology agreement with Delphi Corporation of the United States for the manufacturing of V5 compressors and liquid-gas separators. After introducing this technology, the V5 compressor products reached the internationally advanced level of the 1990s, filling a domestic gap.

In 1998, the company also initiated a research and development project for the SE7PV16 automotive air-conditioning compressor and achieved a successful breakthrough in its development by year 2001, with its performance reaching the VDA standard which represented the highest level in the global automotive industry at that time.
