Suzhou Kangqi Environmental Technology Co., Ltd., is located in Suzhou, the birthplace of China's cleanroom industry. It is recognized as an outstanding leading talent enterprise in Suzhou, a national high-tech enterprise, a standard-setting unit for the national standard "Cleanrooms and Associated Controlled Environments Part 3: Test Methods," and an ISO9001 quality management system certified company. The company’s products are CE certified for export, and it was awarded the first prize in the 2023 "Sci-Tech Innovation Suzhou" Youth Science and Technology Entrepreneurship Competition, the 2023 Industry Outstanding Contribution Award, and holds an AAA credit rating. It is also certified under the Intellectual Property Management System and is recognized as a top 100 quality supplier in the clean industry.

Founded by a technical team deeply rooted in the cleanroom industry, the company’s core product components, such as sensors, are developed by a postdoctoral team from the Chinese Academy of Sciences (CAS), which has dedicated decades to the study of condensation nuclear particle counters (including one CAS postdoctoral researcher and three CAS PhDs). Driven by technological innovation, the company has obtained dozens of core invention and utility model patents. Adhering to a customer-centric philosophy, the company aims to achieve win-win outcomes with its clients and is committed to advancing the cleanroom industry.

The company specializes in the research, development, production, and sale of cleanroom testing instruments (such as laser particle counters, airborne microbial samplers, air volume instruments, high-efficiency filter leak detectors, pure water fog generators, pressure relief valves, clean environment testing components, etc.) and online monitoring systems for clean environments. These products are primarily used in clean environments like pharmaceutical factories, electronics factories, semiconductors, hospitals, laboratories, precision manufacturing, aerospace, cosmetics, food factories, new materials, and automotive industries. Our typical clients include leading enterprises such as CSPC Pharmaceutical Group, BYD Group, Sichuan Dongcai Technology Group, Wuxi Lead Intelligent Equipment, Changxing Aviation, Tsinghua University, Sanjinkuang Optoelectronics, Gansu Hailiang, Hisense Group, and Zhenqu Semiconductor, to whom we provide cleanroom environment testing, IoT online monitoring solutions, as well as training, calibration, metrology, testing, and validation services.

"Breathing Life into the Cleanroom!" With continuous innovation and dedication, Kangqi is committed to providing customers with more comprehensive technical guidance, cost-effective products, high-quality cleanroom system solutions, and meticulous application support services.
