Types of Ultrasonic Units and How to Choose the Right Model

Ultrasonic units are devices that use ultrasonic waves to clean debris and contaminants from items or surfaces. They provide precision cleanliness while reducing cleaning time and are utilized in a wide variety of industries, including aerospace, electronics, healthcare, manufacturing. Ultrasonic units come in a broad range of types and sizes, each designed to fit different needs. Here, we discuss the different types of ultrasonic units and how to choose the right model for your specific application

Aqueous Cleaning

Types of Ultrasonic Units

Industrial ultrasonic units range in size from smaller benchtop models to large multi-tank automated models. Let’s explore some of these options. 

Bench Top Ultrasonic Cleaner

Bench top ultrasonic units (also called table top ultrasonic cleaners) are relatively small, often portable devices designed for cleaning small items. They are ideal for use in laboratories, manufacturing facilities, machine shops, and other environments requiring ultrasonic cleaning for small parts. Bench top tank sizes range from 2 gallons to 50 gallons and beyond. They are easy to use and tend to be manually operated. Bench top ultrasonic cleaners are usually used for light-duty application such as cleaning surgical instruments, optical parts, and machined components, but using the right cleaning solution, they are suitable for use with heavier duty cleaning such as that required for certain automotive parts. 

Large Ultrasonic Cleaner

As their name suggests, large ultrasonic cleaners have a higher capacity than bench top models and are designed for cleaning larger items. They are often used for precision cleaning of automotive parts, machinery, and large musical instruments. While these units have larger tanks, they operate at the same standard frequency as other units (40 kHz). Although, similar to other models, other frequency options (25, 68, 170 kHz) are available. These units have a larger tank allowing for cleaning of larger items quickly and effectively.  

Immersible Ultrasonic Cleaner

Immersible ultrasonic units (immersible transducers) are designed for use with existing systems. UPCorp’sVibra-bar transducers can be bonded and wired to an existing stainless steel container that is sealed with a stainless steel lid. Multiple types of immersible transducers are available, including bulkhead, bottom mount, wall hanging, and custom options. These units can be customized with different frequencies and power levels to meet specific cleaning needs. 

Custom Ultrasonic Cleaner

While there are specialized ultrasonic cleaners available such as those specifically designed for cleaning musical instruments or firearms, with so many unique applications for ultrasonic cleaners, there are many cases when a standard model simply isn’t suitable. Custom ultrasonic units can be designed for a vast range of applications, for example, projects that involve unique process flows or unusual object sizes, or that demand superior cleanliness. Custom units can be designed to meet specific size and power requirements and can be equipped with different options, such as temperature control and filtration systems.

Automated Ultrasonic Cleaner

Automated ultrasonic cleaning units are typically designed for high-throughput cleaning operations. They are often used in automotive and aerospace manufacturing, where thousands of parts need to be cleaned quickly and efficiently. Automated units are equipped with robotic arms and other features that allow them to clean parts automatically. 


Factors to Consider When Selecting the Ideal Unit

Tank Size 

The size of the ultrasonic unit's tank is one of the most critical factors to consider when selecting a unit. The tank should be large enough to accommodate the item or items to be cleaned, but not so large that it wastes cleaning solution or energy. Note that for thorough cleaning, the object must be fully submerged in the cleaning solution. 

Ultrasonic Power and Frequency 

The power output of the ultrasonic unit is another critical factor to consider. Higher power units are more effective at removing dirt and grime from items, but they also consume more energy and can be more expensive. The frequency of the ultrasonic waves can also affect cleaning effectiveness, with higher frequencies being more effective at removing smaller particles. 

Cleaning Solution 

The type of cleaning solution used with the ultrasonic unit can impact the effectiveness of the cleaning process. Different solutions are designed for different types of cleaning tasks, such as removing grease, oil, or dirt. It is essential to select a cleaning solution that is compatible with the ultrasonic unit and the item being cleaned. 


If you’re opting for a multi-tank unit, the configuration of the system will be top of mind. The stages required will depend on the application, but might include a cleaning stage, multiple rinse stages, and a drying stage. The configuration can affect the cleaning effectiveness and the amount of energy required to clean items. 


Durability is another critical factor to consider when selecting ultrasonic cleaning equipment. The unit should be built with high-quality materials that can withstand the rigors of the cleaning process. It is also essential to consider the durability of the tank, transducers, and other components, as these parts can wear out over time and require replacement. 


The manufacturer’s warranty is an important consideration when selecting an ultrasonic cleaning unit. A warranty can provide peace of mind and protect the investment in the unit. It is essential to review the warranty carefully and understand the coverage and terms before making a purchase. Related to this, you'll ideally want to select a manufacturer with a reputation for providing excellent customer service. 

Final Comments

Ultrasonic cleaning is a powerful method used to clean a wide variety of items and surfaces. When selecting an ultrasonic unit, it is important to consider factors such as tank size, power output, configuration, and durability. By carefully evaluating these factors and selecting the right unit for your needs, you can achieve optimal cleaning results and extend the life of your items and equipment.
