Jiafeng Environmental Protection Air Conditioners (Industrial Air Coolers) have passed 17 quality inspections by the Guangdong Quality Supervision and Inspection Institute, proving to be incredibly robust!
We all know that quality inspection agencies come in various levels: private, municipal, provincial, and so on. Jiafeng has passed the very authoritative provincial quality inspection unit!
The Guangdong Testing Institute of Product Quality Supervision, also known as the Guangzhou Electrical Safety Inspection Institute of the National Administration for Quality Supervision, Inspection, and Quarantine, and the Guangdong Institute of Testing and Certification, is a sub-ministerial-level public institution directly under the Guangdong Administration for Market Regulation (Intellectual Property Bureau).
JiaFeng Water-Cooled Air Conditioning (Evaporative Cooler) quality inspection is not only conducted by authoritative institutions but also includes up to 17 inspection items!
If one quality inspection is a mere formality, two are sheer luck, and three are fate, then seventeen inspections are confidence and strength!
