Recently, Hanas completed the installation training of three washing screens for residual materials in a domestic carbon black factory. The on-site training content includes equipment usage, product testing process, and analysis of common problems.

The NDA-VACU washing screen residue detection equipment developed by KRAHNEN and assembled and sold by HITEC meets the relevant testing standards of ATM D7724, especially playing an important role in the washing screen residue detection of special carbon black. The NDA-VACU has no smoke, low noise, and no sewage splashing during the entire testing process, which greatly improves the testing environment compared to traditional washing screen residue equipment.
