Safety is always our most important commitment to customers. As accessories or equipment used under high pressure for a long time, passing the world's highest level of safety certification is our guarantee for customers. After more than half a year of revision and improvement, engineers from EU certification have issued MD certifications to the full range of column packing machines produced by Zhansa, and PED certifications to the full range of prepared packing column tubes. In the future, we will implement stricter product production control within the EU certification system and provide customers with the safest and most efficient tools.
