Brand Heritage: Jiefeng’s Journey in Magnetic Bearing Technology
MULTISTACK Jiefeng began its exploration of magnetic bearing technology in the 1990s. In 1992, the Australian MULTISTACK R&D team initiated the development of oil-free magnetic-bearing centrifugal refrigeration compressors, establishing the dedicated TURBOCOR R&D division the following year to focus on technological breakthroughs. As the cradle of magnetic bearing compressor technology, MULTISTACK Jiefeng became a pioneer in its commercial application after successfully launching the world’s first product.

In 2005, MULTISTACK Jiefeng produced China’s first magnetic-bearing chillers, which were initially deployed in a Singapore commercial project, validating the technology’s stability in Southeast Asia’s high-temperature, high-humidity environments. Since then, MULTISTACK Jiefeng’s magnetic-bearing cooling technology—centered on "oil-free operation, intelligence, and high adaptability"—has expanded into diverse sectors, including data centers, rail transit, commercial complexes, new energy, healthcare, and cold-chain logistics, delivering energy-efficient cooling solutions across industries.

Conclusion
The collaboration with Astra Group not only marks another solid step for MULTISTACK Jiefeng in the Indonesian market, driven by its technological prowess, but also signifies the opening of a new chapter for high-efficiency cooling in Southeast Asia. As the world advances toward "dual-carbon" goals, Jiefeng will continue to empower industries with its leading magnetic-bearing technology, driving energy efficiency upgrades and contributing to a sustainable future.
