The electronics manufacturer VTQ Videotronik produces electronic components and complete electronic devices. The core of the production consits of several soldering systems. These are filled with nitrogen (N2) to avoid oxidation on the circuit boards. In the course of modernization measures in the production, onsite nitrogen generation was also optimized. In addition to two INMATEC generators, an additional hydrogen catalyst now provides high-purity nitrogen. By using the NKat system, a significant reduction in compressed air consumption and energy costs was achieved.
