##Shenzhen, Dongguan, Huizhou, Guangzhou, and Foshan have comprehensive coverage, and localized services have laid a solid foundation

The manufacturing industry in the Greater Bay Area is intensive, and the demand for clean environments in the four pillar industries of electronic information, new energy lithium batteries, biomedicine, and food processing is booming. However, many purification companies in other places only accept orders remotely, with long construction periods and no guarantee of after-sales service, which makes the enterprise suffer greatly.

Leading companies such as Desay SV, EVE Energy, and Jiuhui Pharmaceutical are its long-term partners. From the 100000 level constant temperature and humidity food workshop in Fuhai Street, Bao'an, Shenzhen, to the 1000 level dust-free workshop in Zhongkai High tech Zone Electronics Factory, and to the low dew point drying room in Daya Bay New Energy Enterprise, Huajianjing's footprint has been deeply embedded in every industrial hotspot of Shenzhen, Dongguan, Huizhou, and Foshan.

##Technology is king, the hard work behind the 99% acceptance rate

Huajianjing has created a unique five stage quality control system, strictly benchmarking against ISO 14644-2 clean construction standards. The one-time acceptance rate of the project is as high as 99%, far exceeding the industry average of 92%. The company has fully implemented digital twin and BIM modeling technology, optimized airflow layout through 3D visualization, and helped reduce energy consumption in clean workshops by more than 30%. The self-developed intelligent clean monitoring system can monitor temperature and humidity, dust particles, pressure difference, dew point and other data in real time, automatically warn of abnormalities, and truly achieve digital unmanned operation and maintenance.

In the customer satisfaction survey, Huajianjing ranked first with a high score of 9.9 and a repurchase rate of up to 85%; — This is not a marketing tactic, but a true reputation that 85% of customers choose to trust again.
