On April 22, 2025, Zhejiang Sanwei Energy-Saving Technology Co., Ltd. successfully won the bid for an industrial land parcel and its above-ground buildings in the Zhongdian Smart Valley Industrial Park, Huangwan Town, Haining City, officially marking the company's establishment in the Jiaxing region. As a branch of Zhejiang Sanwei Electric Appliance Co., Ltd., the company is dedicated to the manufacturing of refrigeration and air-conditioning equipment.

      The new base covers an area of 752.85 square meters and is located in Building 13 of the Zhongdian Smart Valley Industrial Park in Huangwan Town, Haining City, with an investment intensity of 7.96 million yuan per mu. As an important part of Sanwei Electric Appliance's strategic layout in the energy-saving and environmental protection sector, Sanwei Energy-Saving Technology will leverage its parent company's technological expertise and market resources to focus on developing high-efficiency energy-saving heating and cooling equipment.

      Since its establishment, Zhejiang Sanwei Electric Appliance Co., Ltd. has been committed to the research and application of energy-saving and environmentally friendly technologies. Its water-source and ground-source heat pump units have demonstrated strong performance in terms of energy efficiency. According to technical data, water-source and ground-source heat pump technology currently achieves one of the highest coefficient of performance (COP) values among air-conditioning systems for both cooling and heating. In actual operation, the COP can reach 4–6, meaning that with 1 kW·h of electricity consumption, users can obtain 4.3–5.0 kW·h of heat or 5.4–6.2 kW·h of cooling capacity.

      Zhejiang Sanwei Energy-Saving Technology Co., Ltd. will continue the technical approach of its parent company, focusing on developing more energy-saving and environmentally friendly heating and cooling products. The company plans to launch a range of products, including water chillers, air-cooled water chillers, screw-type water chillers, and air-source heat pump water heaters, to meet market demand for high-efficiency energy-saving equipment.

      Located in the core area of the Yangtze River Delta, Haining City enjoys a superior geographical position and convenient transportation, providing favorable locational conditions for the development of Sanwei Energy-Saving Technology. As a key industrial platform in the local area, the Zhongdian Smart Valley Industrial Park is home to a cluster of high-tech enterprises and offers a well-developed industrial chain supporting environment.

      A company representative stated that Sanwei Energy-Saving Technology will fully leverage the parent company's accumulated expertise in energy-saving technologies, combined with the industrial policy advantages of the Jiaxing region, to develop more energy-saving and environmentally friendly heating and cooling products and provide customers with more efficient solutions. At the same time, the company will actively collaborate with other enterprises in the park to jointly promote the development of the regional energy-saving and environmental protection industry.

      With the deepening implementation of China's energy-saving and emission-reduction policies, market demand for high-efficiency energy-saving refrigeration and air-conditioning equipment continues to grow. The establishment of Sanwei Energy-Saving Technology not only enriches the product line of Zhejiang Sanwei Electric Appliance Co., Ltd. but also provides the market with a greater selection of energy-saving equipment options.

Looking ahead, Sanwei Energy-Saving Technology will rely on the technical support of its parent company, continuously strengthen product research, development, and innovation, and provide customers with more energy-saving and environmentally friendly heating and cooling equipment solutions, contributing to China's energy conservation and emission reduction efforts.
