The quality at ZELU stems from responsibility. We use only carefully selected raw materials from qualified suppliers in Europe and Asia. Using product-specific incoming tests we check every raw material before it is released for use in production. Everything is subject to outgoing controls to help us maintain the quality of our products at a consistently high level. This has been the case for many years. Thus we can guarantee our customers reliable production and processes. That’s what ZELU stands for.
