Dunan Central Air Conditioning, founded in 1987 and affiliated with Dunan Environment, is an integrated provider of HVAC and air conditioning equipment, specializing in research, development, manufacturing, sales, and service, as well as offering system energy-saving solutions. The company holds a significant market share in the field of nuclear power plant air conditioning, being a pioneer in setting the standards. It leads in the market share for dry-type finned tube coolers in the industrial purification sector and is a promoter of energy-saving technology for elliptical tube heat exchangers. The company serves as a major supplier for energy-saving air conditioning systems in the data communication industry, catering to three major operators. It is also an excellent supplier of air conditioning equipment in the rail transit industry, providing integrated environmental control system equipment for rail platforms and air conditioning equipment for rail vehicles, establishing numerous benchmark projects in key cities nationwide.
Entrepreneurship, creation, and innovation are ingrained in the blood of Dunan people. The technical personnel of Zhejiang Dunan Mechatronics Technology Co., Ltd. are proactive, bold in breakthroughs, and have independently developed high-efficiency, low-resistance air purification units using elliptical tube heat exchangers, two-stage compression centrifugal chillers, redundant heat exchanger chillers with falling film evaporators and parallel screw compressors, and high-tech products such as nuclear-grade safety-rated nuclear power units.
With a people-oriented approach, Dunan has gradually established a technical support system with independent intellectual property rights. To achieve this, the company has engaged in extensive cooperation and exchanges with well-known Chinese universities and research institutions. In collaboration with Hefei General Machinery Research Institute, Zhejiang University, Xi’an Jiaotong University, and other top research institutions, Dunan has jointly established the “Dunan Central Air Conditioning Research Institute.” The institute has gathered elite professionals in the domestic refrigeration industry, aiming at leading levels and development trends in the domestic and international refrigeration industry. They work diligently to ensure that Dunan Central Air Conditioning products maintain technological leadership. The institute’s independently developed precision constant temperature and humidity units, environmentally friendly water (heat pump) units, ducted air conditioning units with air duct delivery, and purification combined air handling units have all passed provincial evaluations and received high praise from industry experts. The company strives for novel product designs, superior performance, high energy efficiency, easy installation, and simple operation. In particular, its advanced features in intelligent control, energy conservation, environmental protection, and remote telephone control applications have been recognized by Chinese authoritative experts, earning the evaluation of being “ahead of similar products in China and reaching international advanced levels.” Many of its technologies have filled gaps in China’s technical knowledge.
Quality is our character and the life of our enterprise. Dunan people deeply understand that an uncompromising commitment to quality and strict quality management are powerful guarantees for building the Dunan brand and providing a solid foundation for business development. In the early 2000s, Zhejiang Dunan Human Environment Equipment Co., Ltd. became the first central air conditioning enterprise in China to pass ISO9001:2000 quality system certification and took the lead in introducing the TQM large quality management system. Adhering to the philosophy of “a common society, a common home, a common responsibility, and a common Dunan,” the company actively implements environmental system management and has smoothly passed ISO14001 environmental system certification.
