VEVOR 30L Ultrasonic Cleaner Dual Frequency Ultrasonic Cleaning Machine with Heater Jewelry Cleaner for Parts Jewelry Eyeglass Ring Denture Record Circuit Board 28/40KHz

Stainless Steel Tank for Long-Lasting Corrosion Resistance 

The VEVOR 30L ultrasonic cleaner has a tank made of high-quality stainless steel, designed to withstand repeated exposure to water, solvents, and cleaning products. The tank's anti-corrosion, rust-proof design keeps its structure strong even after long-term daily use in harsh environments such as industrial labs and professional workshops. A durable material choice is not just for looks; it also extends the unit's useful life by blocking chemical breakdown that would damage a lower-quality material over time.

In addition to the tank, the stainless steel shell creates a sealed, leak-proof enclosure that safeguards interior parts and maintains stable liquid levels during each cleaning cycle. Whether you are running continuous operations in a medical setting or cleaning jobs here and there in a small shop, this machine's solid construction means that it will work reliably every time. Because the materials are long-lasting and manufacturing standards are strict, your investment will last for a long time.

Dual 28/40KHz Frequency Modes for Thorough Ultrasonic Cleaning 

A key feature of this 30L ultrasonic cleaner is its dual-frequency operation at two frequencies, 28KHz and 40KHz, allowing users to adjust the cleaning action to the item they are working on. The 28KHz sweep mode produces larger, stronger cavitation bubbles, which are ideal for degreasing heavy-duty metal parts, engine parts, and thick materials. When you switch to 40KHz Turbo mode, the bubbles are smaller and more numerous, which makes them softer and better at cleaning delicate items like jewelry, circuit boards, and optical lenses.

Because of this frequency flexibility, you do not need more than one machine for different cleaning jobs. By changing the frequency mode, a single unit can work with tough industrial parts in one cycle and delicate precision instruments in the next. This makes the machine very useful in many fields, such as manufacturing electronics, maintaining dental and medical equipment, servicing watches, and cleaning food-grade tools, all without losing cleaning effectiveness or risking damage to delicate items.

600W Ultrasonic Power with 10 Transducers for Deep Penetration 

With a total output of 600W, the 30L ultrasonic cleaner features 10 high-performance transducers that work together to create uniform cavitation energy throughout the tank. This setup helps distribute ultrasonic energy evenly. The large number of transducers also spreads mechanical stress more evenly, which prevents hotspot wear and makes the unit more reliable over time.

Contaminants stuck in long channels, narrow crevices, blind holes, and recessed geometry are especially easy for the 600W power output to remove. Many of these areas are difficult to reach using conventional cleaning methods. The ultrasonic transducers create microscopic cavitation bubbles that remove oils, waxes, residue, and contaminants. The result is a deep, contact-free clean that preserves the surface structure and meets standards that are hard to reach with traditional methods.

Adjustable 0–80°C Heating for Optimized 30L Ultrasonic Cleaner Performance 

The 500W built-in heater lets users set the liquid temperature from room temperature to 80°C. This allows users to match cleaning temperature to different contaminants and materials. Higher temperatures make liquids less viscous, break down grease and biological contaminants faster, and make cleaning detergents work better. This makes the 30L ultrasonic cleaner much more useful than non-heated models. 

The machine also has an auto-standby mode, a sleep mode, and a memory function that retains temperature and time settings if the power goes out. This is especially helpful in workplaces where shifts or operators need consistency. The memory function makes sure that every new cycle starts with the same validated settings. This reduces setup time and operator variation. Once the cycle is complete, the unit automatically enters sleep mode, protecting components and saving energy without any user intervention.

Degas, Sweep & Turbo Modes for 30L Ultrasonic Cleaner Control 

Users have fine-grained control over the cleaning process through three working modes. The Degas mode removes dissolved gases from the cleaning solution before operation begins. This is an important step when working with delicate parts or when getting the most out of cavitation is critical. Dissolved gases can prevent bubbles from forming and reduce cleaning effectiveness, so degassing the fluid first makes a big difference. This feature is particularly useful for laboratory, pharmaceutical, and electronic applications. 

The Sweep (28KHz) and Turbo (40KHz) modes provide different cleaning intensities for various applications. Users can create effective multi-stage cleaning routines that use a single machine. For example, they can use a degassed solution to pre-treat highly soiled parts, sweep mode to remove surface grime, and turbo mode for fine cleaning. This level of operational control is what sets the VEVOR unit apart from other units that operate in only one mode.

User-Friendly LED Display and Portable Design for Easy Operation 

The LED screen displays the current temperature and elapsed time, allowing operators to monitor cleaning progress. The 0–30-minute timer lets you precisely control the cycle, and the panel's layout makes it easy to set up without consulting a manual, which is helpful in busy business settings or for people who are just starting to use it. 

The unit's design shows that considerable thought went into usability. The portable carry handle makes it easy to move, even though it holds 30 L. While it is working, the machine stays stable on workbenches thanks to rubber, non-slip feet. The built-in water drain plug makes it easier to empty the tank after each cycle, and the included lid retains heat and prevents splashing. Heat-dissipation vents help protect internal components from overheating.
