Brand Story

Twenty years ago, in the tide of the vigorous development of industrial manufacturing, a group of dreamers gathered together. Mr. Ren Zhanzhi, the founder, wrote in his diary: "We are not about cold machines, but systems that can sense temperature and care for life." With this Original intention, the first factory building was completed in Dezhou, Shandong Province, and the first independently developed commercial central air conditioning was rolled out， starting our persistent pursuit of "precise temperature control".

After four years of dedicated research and development, we overcame the core technology of efficient heat exchangers and launched the "Energy Efficiency Pioneer" series, with an energy efficiency ratio leading the industry by 15%. That year, our products were exported to Southeast Asia for the first time, marking the first step of internationalization.

The first overseas project - the Vietnam Hanoi International Conference Center was successfully delivered, marking our beginning to step onto the international stage. The veteran workers on the production line still remember: "To achieve a temperature difference accuracy of 0.1℃, we tested hundreds of times, and finally broke through the foreign technical monopoly."

With the rise of the Internet of Things technology, we were the first to integrate intelligent control systems into central air conditioners， launching the industry's first smart units that can be remotely monitored and self-adjusted.

We established a national-level laboratory and formed a joint research center with three universities. The number of patents exceeded 200. And we were the first to propose the concept of "Air Conditioning as a Service", launching the industry's first smart cloud control platform.

In 2015, we completed a fully automated sheet metal production line, increasing production capacity by 300%. During the pandemic in 2020, we urgently provided negative pressure room-specific air conditioning systems to multiple hospitals and won the "Outstanding Contribution to the Fight Against the Epidemic" award.

Facing the global climate change challenge, we fully committed to the research and development of environmentally friendly refrigerants, launching a full series of carbon-neutral product lines.

The factory completed solar energy renovation, reducing carbon emissions by 3，200 tons per year, and was awarded the "National Green Factory" title.

Today, we have a 120-acre digital production base, with an annual production capacity of over 5 million units of high-end central air conditioning equipment and accessories, and a service network covering 40 countries and regions around the world. But what remains unchanged is the faded slogan at the entrance of the workshop: "Each unit of equipment is our commitment to temperature."
