Dezhou Yatai Group is located in the Dezhou Economic Development Zone, which is situated in the northwest of Shandong Province and is known for its reputation as "the Gateway to the Capital and the Thoroughfare of the Nine Provinces." The total area of the group covers 7.7 million square meters, with a total investment exceeding 1 billion yuan, fixed assets worth over 700 million yuan, an annual sales volume of 3.3 billion yuan, and nearly 400 million yuan in tax revenue. The group currently has 3,200 employees, 37% of whom are technical personnel, including 10 professor-level senior engineers. The group owns three wholly-owned subsidiaries and one joint venture, and has invested in establishing several economic entities such as Shandong Huayu Vocational and Technical College, Yatai Real Estate Development Co., Ltd., and Dezhou Huachen Driving School. China's refrigeration industry began in the 1950s, based on the introduction of Soviet refrigeration technology, and has developed through the dedicated research of several generations. After the reform and opening up, China's refrigeration industry experienced unprecedented growth, especially since the 1990s when the central air conditioning industry rapidly expanded. It was during this period that Dezhou Yatai Group was established, riding the wave of development. Since its establishment in 1994, Yatai Group has always adhered to the entrepreneurial goal of "creating world-satisfying brands," following the business philosophy of "surviving through the market, taking quality as the foundation, ensuring credibility, leading with science and technology, and putting customers first," and persisting on the path of combining production, education, research, and trade. Integrating R&D, production, sales, installation, and service, the group strives to build a top-tier national brand. After 20 years of development and construction, Yatai has forged a unique path of its own. Especially since entering the 21st century, the overall scale of the enterprise has undergone tremendous changes. It is now a diversified large-scale enterprise group that integrates the design, production, installation, and service of central air conditioning equipment, clean air conditioning equipment, and environmental technology materials. Yatai's products mainly fall into three major series, comprising over 300 types and more than 800 items, covering the entire range of equipment in the fields of central air conditioning, fire protection and ventilation, clean engineering, and air conditioning accessories. With strong production technology, exquisite craftsmanship, advanced production equipment, and a full range of high-quality air conditioning products, the group has established four national-level testing centers equipped with advanced testing methods. In 2002, Yatai Group participated in the "China Refrigeration Exhibition" held in Shanghai for the first time, successfully showcasing its overall strength and corporate culture, and was hailed by peers as the "Dark Horse of China's Refrigeration Industry," marking the beginning of Yatai's development legend! Yatai's central air conditioning products include: main units, terminal products, fire protection and ventilation products, clean air conditioning products, fiberglass composite material products, and air conditioning accessory products. Among them, the main units include water-cooled and air-cooled series. Water-cooled units include water-cooled chillers, water-source and ground-source heat pumps, surface water, and sewage source units; air-cooled units include air-cooled heat pump units, air-cooled modular units, and air-cooled household units; industrial units include rooftop combination units, constant temperature and humidity units, and humidifiers. All main units adopt screw heat pump technology, achieving a reasonable match and technical processing, meeting the national policy requirements of energy saving, environmental protection, and low carbon, with an energy-saving rate of 30-35%, and an energy efficiency ratio of 5.5-6.0. Terminal products include fan coil units and air conditioners, with the fan coil units being produced in a full series, all certified by national authoritative departments, and are one of the leading products with independent intellectual property rights owned by the Yatai Group. Air conditioning units are independently developed and manufactured, strictly following national standards, and currently occupy a significant market share, exporting to many countries in Europe and America. Yatai's fire protection and ventilation products, starting from the early production of fire smoke exhaust fans, have now developed into dozens of varieties, including subway-specific fans, nuclear power special fans, and industrial fans, becoming a new growth point for business development. These products are widely used in subway projects, nuclear power projects, civil air defense projects, and other fields. Fire dampers, smoke exhaust dampers, and silencers are exported in large quantities to neighboring countries such as India, Pakistan, Vietnam, Myanmar, and some African countries. In recent years, Yatai has made significant investments in the R&D of clean air conditioning products. In 2006, through technical cooperation with Apollo Company of the Netherlands, the clean air conditioning technology of Yatai was greatly enhanced, particularly in the field of cleanroom purification, where it has become highly competitive. Currently, we can independently complete local Class 100 and Class 1000, as well as medical Class 100 and Class 1000 operating rooms. Fiberglass composite material products are the original products of the Yatai Group, with very mature technology, and the company is also involved in the drafting of many national standards. Our current fiberglass technology is the third generation, solving the technical problems of traditional fiberglass products, such as chlorine return and easy powdering. "To do a good job, one must first sharpen his tools." Over the past 20 years, Yatai Group has introduced more than 100 sets of advanced equipment and production lines from countries such as the United States, Germany, Italy, and Japan, fully ensuring product quality and performance. In terms of quality control, in 2002, the group invested heavily in setting up four national-level testing centers, strictly manufacturing according to the requirements of the ISO9001 quality management system and the ISO14001 environmental management system. In terms of brand building, Yatai is a well-known trademark in China, a famous trademark in Shandong Province, and a Shandong brand. Yatai is one of the first enterprises in China to obtain an industrial product production license and has been successively admitted as a member unit by the Chinese Society of Refrigeration, the China Association of Refrigeration, the China Fiberglass Association, the Clean Technology Branch of the Chinese Institute of Electronics, and the China Quality Inspection Association. Yatai's central air conditioning main units and terminal products have been rated as trustworthy products by the State Administration for Market Regulation, and the group has been awarded the title of "National Trustworthy Enterprise in Refrigeration Equipment Quality."
