Pulse Water Jet (PWJ)

For any industry that practices surface preparation or coatings removal, our technology is faster, operates longer and costs less to maintain.

Technology Summary

Ultrasonic vibrations created by a transducer are used to modulate a stream of water as it transforms a continuous water jet to a fully developed pulse water jet. The pulses serve to rapidly load and unload a force on the targeted surface. Depending on the application and the parameters used, these pulses can be used to strip coatings or prep the surface prior to coating.

Features Benefits & Highlights:

  • VLN Advanced Technologies’ PWJ has multiple patents and is a secured technology
  • System is Clean Green - no additives, chemicals or abrasives are used - just water which can be recycled and reused in most cases
  • Improved performance over high-pressure water jet systems – cheaper to operate, incorporates lower operating parameters to do the same work, higher operating times, lower maintenance costs
  • Exacting precision, repeatability and reliability delivered by programmable robotic manipulations
  • Multidimensional system – can be operated as PWJ or a typical water blaster system when the pulse is turned off
