Ultrasonic & Megasonic Cleaners

Ultrasonic Cleaning Technology

How Ultrasonic Cleaning Works

An ultrasonic cleaner generates high-frequency sound waves, typically in the range of 20 kHz to 200 kHz, which travel through a cleaning liquid such as water or a mild solvent. These sound waves create millions of microscopic cavitation bubbles that collapse rapidly, releasing energy that dislodges dirt, grease, and other contaminants from surfaces.

This process is non-abrasive yet extremely effective, making it suitable for both heavy-duty parts and delicate instruments. Ultrasonic cleaning reaches areas that traditional cleaning cannot, including small holes, blind channels, and fine threads.

Advantages of Ultrasonic Cleaners

• Deep, consistent cleaning with minimal manual effort

• Reduced use of harsh chemicals or aggressive solvents

• Short cycle times, improving productivity

• Safe for complex geometries and delicate materials

• Environmentally friendly and cost-efficient operation

Proftek’s ultrasonic systems are available in bench-top, single-tank, and multi-stage configurations, allowing integration into manual, semi-automatic, or fully automated cleaning lines. Each system can be customised for specific applications, tank sizes, and power outputs.

Common Ultrasonic Cleaning Applications

• Automotive: engine components, injectors, valves, bearings

• Medical & Dental: surgical tools, implants, and reusable instruments

• Electronics: printed circuit boards, solder flux removal, sensors

• Laboratory & R&D: glassware, precision tools, test samples

• Manufacturing: moulds, dies, and precision metal parts

Megasonic Cleaning Technology

When to Choose Megasonic Cleaning

For the most delicate or high-precision components, a megasonic cleaner offers an even gentler and more controlled cleaning process. Operating at frequencies up to 1 MHz, megasonic cleaning replaces violent cavitation with smooth acoustic streaming, which removes sub-micron particles without damaging the surface.

This makes megasonic cleaners essential in fields like semiconductor manufacturing, optics, advanced materials, and medical device production, where contamination can compromise performance or yield.

Benefits of Megasonic Cleaners

• Ultra-gentle action safe for fragile or sensitive components

• Superior removal of microscopic particles and residues

• Reduced particle redeposition and improved cleaning uniformity

• Compatible with deionised water, solvents, and customised chemistries

• Suitable for cleanroom and critical-environment applications

Megasonic cleaning is often used as a final cleaning stage before assembly, coating, or sterilisation, ensuring that every component meets stringent cleanliness specifications.
