2L Mechanical Ultrasonic Cleaner – 0.5 gal 40 KHz Stainless Steel Ultrasonic Cleaning Machine for Industrial and Jewelry

Introduction

The U.S. Solid 40kHz Ultrasonic Cleaner features a professional-grade stainless steel tank with intuitive knob-controlled digital timer and heater (up to 80°C/176°F), delivering fast, thorough cleaning through effortless operation. Its high-end transducers generate intense high-frequency sound waves that create cavitation bubbles in the cleaning solution. When these bubbles collapse, they release energy that removes dirt and grease from all surfaces – including hard-to-reach areas of jewelry, tools, and small industrial parts – without requiring scrubbing. This efficient process, combined with durable stainless steel construction, makes it ideal for both professional and personal use.

Applications

• Wide Applications: You can use the machine to clean glasses, jewelry, dentures, razors, coins, PCB, carburetor, gun parts, automotive parts, brass,injectors, or even chemical fiber material.
• Reliable Quality: FCC, CE, and RoHS certified with 1-year warranty.

FAQ

Problem 1: Why does the actual temperature sometimes exceed my set value?

The ultrasonic cleaning process naturally generates heat through cavitation, which can raise the liquid temperature above your preset level. For best results, we recommend setting the heater 5-10°F (3-5°C) lower than your target temperature to account for this additional heat input.

Problem 2: Can it run continuously?

No. The maximum continuous operation time is ≤30 minutes per cycle. After each cycle, allow the machine to rest for 20 minutes before restarting to prevent overheating and damage.

Problem 3: Can items be placed directly into the tank?

No. Always use the provided basket—never place items directly on the tank bottom. Direct contact may scratch the tank or damage the transducer.

Problem 4: Are there any liquid requirements?

• Never use mineral acids (e.g., hydrochloric acid, sulfuric acid), as they corrode the tank.
• Fill liquid above the 2/3 mark in the tank (mandatory if heating is enabled).

Problem 5: Can it run empty (without liquid)?

Absolutely not. Operating without liquid will damage the ultrasonic generator. Always ensure sufficient liquid before starting.
