The dynamic drainage analyser, DDA, simulates drainage conditions on paper machines and is sold to papermakers, chemical manufacturers and R&D companies worldwide. Earlier this year this equipment was upgraded to model DDA 5 with features like drainage speed, initial drainage and temperature readings presented for chosen time intervals. The productivity has increased as the equipment is automatically cleaned after each analysis.

The total number of DDA units sold is now close to one hundred, with the most recent one delivered to Nalco USA. The company has used a DDA equipment for a number of years and is now replacing the old one with the new DDA 5 model in order to make use of its new features and improved efficiency.
