Highlights POWERFLOW e N2 - Full-Tunnel Wave Soldering System

  • Compact full-tunnel wave soldering system for cost-optimized wave soldering under a nitrogen atmosphere with a fast ROI
  • Precise and economical flux deposition through freely defined spray pattern
  • External fluxing module with separate exhaust unit, separated from process tunnel
  • Modular preheat configuration for flexible and reproducible heat transfer   
  • Ideal solder nozzle combinations for all application requirements
  • Robust, heavy-duty, durable and automatically lubricated chain conveyor system 
  • Insulated, gas tight process tunnel manufactured from stainless steel raises energy efficiency 
  • Intelligent Nitrogen control ensures optimized N2 consumption and cost efficiency
  • PC-control to manage solder programs and documentation of the process parameters
  • Universal integration in existing peripheral systems



With the Ersa nitrogen-atmosphere wave soldering system POWERFLOW e N2, Ersa presents a basic system for demanding, cost-optimized wave soldering processes. The system focuses on proven machine concepts and offer future oriented and innovative solutions, which provides to its user an optimized process.


The easily accessible fluxer area offers excellent maintainability. With the upper and lower preheaters, the well-insulated tunnel ensures that the boards are completely heated through, even with high-mass assemblies. The coated solder module offers, on account of the availability of different wave formers, for each application the best solder quality and a high degree of repeatability. Nitrogen control with the rest-oxygen monitor maintains the O2 level in the nitrogen atmosphere level at the desired level, thereby saving the media nitrogen.
