Kingfit’s self-developed variable frequency magnetic centrifugal low-temperature chiller earned a spot on this list—its second consecutive year of inclusion. This recognition proves that Kingfit Magnetic Chillers Gain National Recognition through innovation and long-term sustainability.
On May 22, 2025, the China Refrigeration Society held its annual conference in Xi’an under the theme “Smart Cooling, Low Carbon, Green Future.”The event focused on green transformation and innovation in the refrigeration industry, attracting experts from government, academia, and leading enterprises. During the conference, the 2025 China Refrigeration Society Energy-Saving and Carbon-Reduction Product List was announced.
Revolutionary Technology: Variable Frequency Magnetic Chiller
Kingfit’s award-winning product addresses the lack of high-efficiency cooling in the pharmaceutical and chemical industries. It can achieve outlet water temperatures as low as -15°C while delivering more than 30% energy savings compared to traditional screw chillers.
This breakthrough combines permanent magnet frequency conversion with reverse cascade heat exchange technology. Kingfit also secured a national invention patent for this innovation, now in use at Jiangsu Zhengdan Chemical, saving up to 35% energy.
Setting Industry Standards: A Leading Role in Regulation
On March 28, 2025, Kingfit assisted in drafting China’s first national standard for oil-free magnetic centrifugal chillers. The new standard establishes benchmarks for energy efficiency, noise, and vibration, paving the way for a more regulated industry.
With over 3,500 magnetic chillers sold, Kingfit Magnetic Chillers Gain National Recognition technology has helped reduce carbon emissions by 600,000 tons globally. Through innovation and standardization, Kingfit is actively supporting China’s dual-carbon goals and the transition to greener manufacturing.
