Plasma spraying with extreme throughputs

Hybrid water/argon-stabilized plasma (WSP-H) technology at a glance:

  • Evolution of the original Water-Stabilized Plasma (WSP) torch concept which has been serving in the industry for heavy-duty plasma spraying for more than 30 years.
  • Hybrid concept combines benefits of water-stabilization and conventional gas-stabilization principles.
  • System was completely redesigned to bring major improvements to the reliable day-to-day operation, easy "click and spray" operation and maintenance of the torch, higher reliability and longer continuous operation.
  • Developed and supported by Institute of Plasma Physics CAS & ProjectSoft HK, a.s & local dealers.
  • Versatility of the technology and choice of spraying routes allow optimization of coatings microstructures and functional properties for various applications.
  • Technology is ready to be integrated into your sprayshop.

Main benefits

High plasma energy

Enthalpy of WSP-H torch  is more than order of magnitude higher than for  conventional torches based on gas-stabilization.
