In the manufacture of paper, be it when using pure pulp or when using old paper, most different kinds of contamination occur on felts, screens and all machinery deployed.
JULIUS HOESCH offers a comprehensive selection of different cleaning agents for very diverse contaminations.
In this field we work together since 1997 with our longstanding partner, the CORAG AG.
