Managers and process engineers at industrial facilities can use ultrasonic cleaning solutions to reduce the use of chemicals and improve cleaning performance. While turnkey solutions that include ultrasonic generators, transducer and tanks are available, specific industrial cleaning applications often require a more flexible solution. A portable immersible ultrasonic transducer is ideal for meeting these kinds of cleaning requirements.
Drop-In Immersible Ultrasonic Transducer
Kaijo offers several models of immersible ultrasonic transducers. These units can be dropped into existing tanks and they work with any Kaijo ultrasonic generator. They are available in 600 Watt and 1200 Watt versions and operate at frequencies from 26 kHz to 160 kHz. The transducers are hermetically sealed and welded and the enclosure is polished 316L stainless steel. The stainless steel enclosure does not suffer from cavitation erosion and the transducers maintain their performance characteristics over time without degradation.
Typical applications include cleaning parts and components in existing tanks or cleaning items too large to fit in the standard tanks of turnkey systems. Additional requirements involve ultrasonic cleaning at several different frequencies and with different transducer configurations. Kaijo’s immersible ultrasonic transducers can be placed in any tank in single or multiple configurations. They can be mounted horizontally or vertically and transducers can easily be changed to handle different cleaning problems.
Using Immersible Ultrasonic Transducers
Facility managers and process engineers faced with industrial cleaning tasks can save time and money by replacing chemical-based cleaning and mechanical scrubbing with ultrasonic cleaning. Immersible transducers can often be placed into the tanks already used for cleaning. Instead of using harsh chemicals, the tanks can be filled with water only or water with a mild solvent. The transducers generate tiny bubbles that clean rapidly and thoroughly.
A key factor in ensuring effective cleaning with ultrasonic transducers is to select the correct power and frequency. Low frequencies such as 26 kHz and 38 kHz generate comparatively large cavitation bubbles that may damage delicate parts when the bubbles collapse during the cleaning action. High frequencies such as 130 kHz and 160 kHz produce smaller bubbles that collapse with less energy and result in finer, gentler cleaning. The power of the transducer affects the number of bubbles the transducer generates. A larger tank will require higher power transducers or several transducers to handle the required cleaning.
For typical industrial cleaning applications a plant may have to clean many types of components and remove various materials. Immersible ultrasonic transducers can provide the flexible cleaning solution required for such situations. For small, delicate parts, a single high frequency transducer might be placed into a small tank. For robust parts with heavy contamination, a low frequency transducer can be placed into the same tank. For large items, several transducers of an appropriate frequency can be placed into a large tank. When a company keeps several transducers of different frequencies and powers on hand, it can respond to various cleaning requirements easily and efficiently.
Companies that replace their chemical and mechanical cleaning systems with ultrasonic cleaning can reduce chemical costs, environmental contamination and improve facility productivity. The immersible transducers are easy to install and move and provide reliable service and trouble-free operation. The flexibility of immersible ultrasonic transducers means companies can start with one or a few transducer for a specific cleaning application and add additional models when they become convinced of the effectiveness of ultrasonic cleaning.
