SweepZone® Technology


SweepZone® Technology

L&R’s SweepZone technology uses “Smart Circuit,” a custom-engineered electronic component that creates Constant Power Output (CPO) for consistent, uniform cleaning. This technology incorporates Pulse Width Modulation (PWM), which enables SweepZone Ultrasonic Cleaning Systems to sense cleaning loads, solution level and voltage fluctuations. What does that mean? L&R’s SweepZone cleaning systems automatically adjust to different conditions to create uniform cleaning power—eliminating hot spots and weak areas.

SweepZone systems:

  • Use a special cleaning wave of +/- 2KHz energy that sweeps back and forth through the tank
  • Provide complete cavitation
  • Provide aggressive cleaning action
  • Are backed by our unprecedented 2 1/2 year warranty
