Telsonic offers a range of ultrasonic cleaning components and modules, including tube resonators, immersible transducers, generators, and compact cleaners.

Tube resonators can be integrated into either pressure or vacuum cleaning systems, with the radial radiation characteristics of these units providing an intense and homogeneous sound field – an essential element for reliable and thorough cleaning.

The company’s RS25 resonator range has been developed to meet Atex standards for installation in potentially explosive environments.

Frequencies of 20, 25 and 40kHz and resonator lengths of between 335mm and 1,700mm enable this range of products to be applied across a broad spectrum of applications.

The robust design and construction of these resonators is said to make them easy to integrate and ensures long-term reliability in arduous operating conditions.

The ‘bolt-on’ concept is a good option for manufacturing, process or maintenance teams that may be considering in-house system build, using ultrasonics to replace an alternative cleaning technology, or retrofitting as a means of upgrading an existing system.

Depending on the application, immersible transducers may be a preferred solution.

These can be custom made to suit the tank size and also incorporate up to 30 transducer heads if required.

Capable of operating at high temperatures and with frequencies of 20, 30, 40 and 80kHz, Telsonic immersible transducers can be matched to any application.

The company also offers a range of compact, fully integrated bench-top cleaning tanks for use in both industrial and laboratory environments.

Ultrasonic technology is used to clean a multitude of component types and sizes.

Miniature parts such as clock mechanisms, delicate items such as circuit boards and optical lenses, or large engineering components can all have dirt, grease, oil or swarf removed using ultrasonic energy.

When it comes to cleaning components within the general mechanical engineering industry, ultrasonic activity has been incorporated for many years as an essential part of solvent and aqueous-based cleaning processes.

The cleaning effect of ultrasound is due to ‘cavitation’.

The ultrasound process generates saturating clusters of miniature gas bubbles, which in turn implode causing local scrubbing shock waves, loosening product contamination and removing it from the surface.

A benefit of this technology is that it can easily penetrate difficult to access areas ensuring the component is completely clean without laborious mechanical and often damaging cleaning actions on the component surfaces.

This ability to reach otherwise inaccessible areas makes ultrasonic cleaning a suitable process for medical components or surgical instruments.

An ultrasonic cleaning system will remove dirt and debris from threaded areas, hinges and serrations on an instrument, leaving the item clean and ready for sterilisation.

With the focus on eliminating hospital-acquired infections such as MRSA and C.diff, ultrasonic cleaning is finding its way into new application areas within hospitals.

Large items, such as trolleys, wheelchairs and bed frames, which are usually steam cleaned, are all capable of being cleaned in an ultrasonic bath.

One of the main benefits of this process is the fact that it is highly repeatable.

Once the parameters such as ultrasound frequency, generally between 20 and 40kHz, operating temperature and time have been established, the hospital can be assured that items will be cleaned to exacting standards.
