Company Profile

Dezhou Chengyun Air Conditioning Equipment Co., Ltd. was founded in 2008 and is located in Dezhou City, Shandong Province—a city renowned as the "Gateway to Heaven and the Gateway to Beijing-Tianjin." The company enjoys a superior geographical location and convenient transportation access. With a registered capital of 10 million yuan and covering an area of 30,000 square meters, the group employs 50 people. In 2024, it achieved sales revenue of 200 million yuan and generated profits and taxes totaling 20 million yuan. As one of China's leading HVAC and refrigeration enterprises, the company boasts strong capabilities in the development, research, and production of complete sets of central air-conditioning equipment as well as related products such as ventilation systems and composite ductwork.

For many years, Chengyun has taken it upon itself to “revitalize the national industry,” continuously pioneering and innovating, and steadily growing to become one of the few large enterprise groups in China’s industry. Chengyun Group is dedicated to the research and development of energy-saving, environmentally friendly, and low-carbon air-conditioning products. It has successfully launched a series of packaged air-conditioning units—including underground-loop, groundwater-based, sewage-source, seawater-source, and ultra-low-temperature water-source heat pump units; rooftop modular air-conditioning units; and constant-temperature and constant-humidity units—as well as such products as ultra-low-temperature air-source heat pumps, multi-split air-conditioning systems, centrifugal water-cooled chillers, and seismic-resistant brackets. Some of these products have reached domestically advanced levels, achieving an overall energy savings of 30%. Chengyun has fully implemented and rigorously operates the ISO9001 quality management system, the ISO14001 environmental management system, and the GB/T28001-2011 occupational health and safety management system. Its packaged units, water-source heat pump units, and air-source heat pumps have all obtained China’s Energy-Saving Product Certification. In 2020, Chengyun was awarded the AAA-level Enterprise Credit Rating Certificate.

In 2024, Chengyun Group invested heavily in the construction of a new-energy charging station project, which was designated by the Dezhou Municipal Government as a key project for that year in Dezhou City.

In 2020, the COVID-19 pandemic struck with great ferocity, deeply worrying people across the country. Under central decision-making and nationwide mobilization, China launched a vigorous battle to contain and control the epidemic. As a leading player in the domestic air purification industry, Dezhou Chengyun Air Conditioning responded promptly and swiftly stepped up to provide assistance. The 600 air handling units produced by Chengyun Air Conditioning were transported to Wuhan at lightning speed and quickly put into service on the front lines of epidemic prevention and control equipment production. Drawing on the full strength of its workforce, Chengyun Air Conditioning manufactured negative-pressure room air purification equipment needed by frontline anti-epidemic institutions—including Wuhan Huoshenshan Hospital, Leishenshan Hospital, Beijing Xiaotangshan Hospital, and the Xi'an Public Health Center—thus building an unbreakable wall of solidarity against the pandemic. This effort sparked widespread acclaim from all sectors of society and also drew the attention of China’s leading medical teams.

All products are developed, designed, manufactured, and inspected strictly in accordance with the requirements of the quality management system, environmental management system, occupational health and safety management system, national standards, and industry standards. From contract review and raw material procurement to final product testing, every stage is rigorously controlled and meticulously documented, ensuring that records for each quality control step throughout the entire production process are fully traceable. We never allow substandard components to proceed to the next stage of production, thereby guaranteeing a 100%合格 rate for all products leaving our facility.
