What frequency is best for ultrasonic cleaning?

The optimal frequency depends on your application. Lower frequencies (20-40 kHz) provide aggressive cleaning for heavy contamination, while higher frequencies (40-80 kHz) offer gentler cleaning for delicate items. Our transducers are designed to match specific cleaning requirements.

How do I install an ultrasonic cleaning transducer?

Installation involves mounting the transducer to the cleaning tank bottom using the provided bolt holes, ensuring proper electrical connections, and waterproof sealing. We recommend professional installation and provide detailed mounting instructions with each product.

What maintenance is required for ultrasonic cleaning transducers?

Regular maintenance includes checking electrical connections, inspecting the transducer surface for damage, monitoring performance parameters, and ensuring proper cooling. We recommend annual professional inspection for optimal performance.

Can these transducers work with different cleaning solutions?

Yes, our transducers are compatible with water-based cleaning solutions, mild detergents, and specialized ultrasonic cleaning chemicals. Avoid highly corrosive solutions that may damage the transducer materials.

What is the typical lifespan of an ultrasonic cleaning transducer?

With proper use and maintenance, our ultrasonic cleaning transducers typically last 5-10 years in industrial applications. Lifespan depends on operating conditions, duty cycle, and maintenance practices.
