Productronic - Nitrogen Improves the Quality of Residual-Current Devices
Nitrogen Generator of Type IMT PN 8820 PAN Ecotube Supplies 40 NM3 Nitrogen Per Hour to the Soldering and Welding Systems
Doepke Schaltgeräte uses various soldering and welding processes in the production of residual-current devices. The nitrogen (N2) required for such processes is produced by an INMATEC nitrogen generator directly on-site at the plant. The self-generated nitrogen not only reduces costs, but also improves the quality of the electronic components installed.
Residual-current devices are used to protect persons against electric shock and to prevent electrically-ignited fires. For example, residual-current devices (RCD) switch the power supply off immediately in the event of dangerously high residual currents occurring. This could be the case if a person touches an electronic device which does not have proper insulation. The RCD measures the incoming and outgoing current in a circuit to this end. The current flow is interrupted if there is any difference. Due to increased safety standards, RCDs must now be installed in all socket circuits in new buildings. For Doepke, founded in 1956, the quality of the sensitive electronic components is thus the top priority when producing life-saving RCDs.
