High Power Ultrasonics

NTS Ultrasonics has developed expertise in the design and building of high power ultrasonic systems. In particular, we can custom design and build protoype high power ultrasonic systems for clients interested in exploring applications in their own R&D.

Recent examples of R&D systems built by NTS Ultrasonics include systems for:

High power ultrasonic technology is suitable for a wide variety of applications including:
ultrasonic cleaning
sterilizing
production of stable emulsions
dispersion of powders in liquids
extraction of oils from organics
increasing yield and reducing processing times for a range of chemical processes
The key to high power ultrasonic applications is the transducer. NTS Ultrasonics designs and builds transducers and sonicators in-house, as discussed on our high power ultrasonic transducer page. We design high power ultrasonic equipment for special applications, and some of our systems can be used for ultrasonic cleaning. We offer consulting services on the design and application of ultrasonic equipment. See below for custom designed transducers and assemblies.
mineral processing (2 different projects)
scale mitigation in pipework in a mineral processing plant
particle separation in slurries for filtration experiments

Custom Designed High Power Ultrasonic Systems

An important part of any custom designed ultrasonic system is the electronic driver, as discussed on our ultrasonic drivers page. NTS Ultrasonics takes an ultrasonic engineering approach to new designs. The application is analyzed and drivers and transducers (or sonicators) are designed accordingly. NTS Ultrasonics is happy to explore new and unusual applications with clients to see if an ultrasonic solution can be developed. We often develop prototypes to allow clients to explore new ultrasonic applications.

Examples of Special Applications of High Power Ultrasonics

NTS Ultrasonics is happy to work with clients on special projects to investigate potential new applications of high power ultrasonics.

Mitigation of solids buildup in pipes.


As an example of a special project, we have recently been involved with field trials investigating the use of high power ultrasonic instrumentation for mitigating the buildup of scale in pipes. Initial results look promising, as shown in the following photographs. These show buildup in the test pipe after 6 weeks, with and without ultrasound. The pipe has 323 mm ID, 5.5 mm wall thickness, and the material is 316 grade stainless steel. The material transported in the test pipe is a slurry found in a mineral processing plant.
Currently, the plant where the test pipe is located shuts the loop down every 4 weeks for cleaning, at a cost of $100,000s in lost production per year. There will be significant savings if the loop can operate for 6 or 8 weeks, or even longer, before shutting down, and high power ultrasonics looks like it will help achieve this.

This technology is new and not guaranteed to work in every situation and so trials are necessary. Contact us if you are interested in discussing a trial on ultrasonic scale mitigation.

Ultrasonic separation.


NTS Ultrasonics was asked by a client to develop a prototype system to demonstrate using ultrasound for particle separation in fliuds. A small high power ultrasonic system was built and, with the use of standing waves, separation was demonstrated.

NTS Ultrasonics can design and build various styles of high power ultrasonic transducer and inverter electronics. All of our transducers and electronics are designed in-house. We specifically design high power ultrasonic equipment for special applications, although some of our systems can be used for ultrasonic cleaning. We offer consulting services on the design and application of ultrasonic equipment.
