Over the course of several decades of development, the company has evolved into an integrated enterprise that specializes in independent research and development, production, sales, and import and export trade of self-control refrigeration components.

During its many years of operation, the company has established a proficient refrigeration technical team that boasts of rich practical experience and has developed a unique welding assembly line and specialized testing equipment. Furthermore, the company has acquired advanced filling technology and invested in various high-tech equipment, including high-precision CNC machining lathes and automated assembly lines to ensure the consistency and stability of products.
