CaviJet® Cavitating Liquid Jets | ||
The CaviJet® technology deliberately induces cavitation in front of the nozzle to produce extremely high, very localized stresses on a surface due to bubble cavity collapse in the jet stagnation region. This provides:

StratoJet® Self- Resonating Jets | ||
The StratoJet® technology utilizes a passive acoustic resonance created by flow interaction with the nozzle and upstream chambers to induce the formation of large vortical ring cavities which collapse on the target. These jets:

DynaSwirl® Cavitating Swirling Jets | ||
The DynaSwirl® nozzle employs a rotating flow to create a very low pressure at the center of the vortex core which cavitates. This cavitation can form a helicoidal shape with a vortex breakdown at the subjected surface near the orifice. This nozzle has several advantages:
Successful applications include:
