With the ministerial and provincial-level automotive air conditioner R&D center, our team of 120 seasoned professionals is large enough to handle complex jobs and independently develop all types of HVAC, cooling units and heat exchangers for various vehicles through our multiple designing platforms. As it turns out, we have more than 20 national technology patents registered every year. In 2002, our company has been approved by ISO9001, QS9000, ISO14001, ISO/TS16949 certifications.

We established China domestic advanced auto air conditioner and heat-exchanger testing Laboratory, Currently, our R & D center has over 90 sets of testing equipment, which can meet the demand of various vehicle air conditioners’ and heat-exchangers’ developing, producing and testing.

In 2009, our testing center has been successfully approved by China National Accreditation Service for Conformity Assessment (CNAS), thus the testing reports issued by our testing center will be recognized in over 46 countries world-widely. In the same year 2009, our laboratory has been approved by China Certification Center for Auto Products (CAP) as CAP’s subcontracted testing laboratory. This is the highest award in auto air conditioner industry in China.
