Tianjin Sandian Automobile Air Conditioning Co., Ltd. is a joint venture with Japan Sandian Co., Ltd., a micro-channel heat exchanger and its components and automotive air conditioning system manufacturer integrating development, production and sales. The company is located at No. 8 Saida 2nd Avenue, Xiqing Economic Development Zone, Tianjin. It was built in 1994, covering an area of ​​54,428 square meters, and has an internationally-level modern experimental center. At present, the company's production capacity is 3.2 million units of automobile heat exchangers per year and 1 million units of automobile air conditioning systems per year.

Since its establishment, with the support of Japan Sandian, it has been committed to the research and development and manufacturing of automotive air conditioning systems and heat exchangers. Technical personnel and operators in key positions of the company were sent to the Japanese headquarters for training. The company's main production and experimental equipment are imported from the United Kingdom, the United States, Japan and other countries, and can carry out product development, experiments and production according to different needs of customers. The high-quality product performance and good after-sales service have won the company's high reputation in the automotive air conditioning market.

Based on experience in the application of microchannel heat exchangers and considering the impact of future environmental changes, the company began to study the application of automotive air conditioning all-aluminum heat exchanger technology in home and commercial air conditioners since 2006. We believe that compared with traditional copper tube aluminum fin type, the application of aluminum copper technology products has the following advantages: 1) Reduced refrigerant usage, green and environmentally friendly, and low carbon emissions; 2) Improved heat exchange performance; 3) Volume of air conditioning system Reduce the cost of logistics and transportation; 4) Reduce the fan volume and reduce noise; 5) Improve the energy efficiency ratio of air conditioners; Given the above advantages, we have seen the prospect of aluminum copper technology in the application of household and commercial air conditioners, and are committed to widely promoting and applying it All-aluminum parallel flow heat exchanger contributes its own strength to environmental protection and low-carbon economy, and our company can also gradually grow in the process. At present, our company has signed development agreements with many world-renowned air conditioners manufacturers.

The internationally advanced production line for domestic and commercial air-conditioning micro-channel heat exchangers will be completed in April 2010. This production line has the ability to produce large commercial parallel flow heat exchanger cores.

Tianjin Sandian is committed to providing customers with innovative, reliable and cost-saving solutions through microchannel technology innovation to meet end customers' pursuit of energy-saving and environmentally friendly products.

In May 2021, Hisense Home Appliances completed the acquisition of Japan Sandian Holdings Co., Ltd. and became the controlling shareholder of Sandian Holdings.
