Question 1

Our Commitment

Accepted Answer

With over 15 years of proven expertise, four state-of-the-art production bases spanning 150 acres, 
                        and more than 100 patents to our name, we specialize in providing high-performance climate control 
                        systems that address the complex challenges of modern facilities.

Question 2

Four Advanced Production Bases

Our strategically located facilities in Qingdao, Dezhou, Ningbo, and Qingyuan form an integrated 
                    manufacturing ecosystem equipped with cutting-edge technology. Each base features five international-standard 
                    production lines, advanced laser cutting systems, robotic welding stations, and national-level testing 
                    laboratories that simulate real-world conditions from -40°C to +55°C.

This infrastructure enables us to produce a comprehensive range of HVAC equipment including water-cooled 
                    and air-cooled chillers, air source and ground source heat pumps, precision air conditioners, fan coil 
                    units, air handling units, and specialized systems for cleanrooms and extreme environments. Our modern 
                    storage facilities and automated inventory management ensure rapid order fulfillment and consistent 
                    product availability.
