28 kHz ultrasonic frequency for deep and aggressive cleaning items both inside and out

Under the same ultrasonic intensity, 28 kHz ultrasonic wave can create more cavitation and make much better in penetration than the ultrasonic wave close to 20 kHz. Therefore, 28 kHz ultrasonic wave works well in cleaning products with complex surfaces or blind holes. Especially, 28 kHz the ultrasonic wave causes much less noise than ultrasonic waves close to 20 kHz.

Heat to Remove Oil and Wax

Heating can decrease the adhesive strength of oil and wax to certain stuffs to be cleaned, make the cleaning solution much easiler to create cavitations under ultrasonic wave and strengthen cavitation so as to increase the cavitation level of cleaning solution, and then enhance the cleaning effect.

Note: the best cavitation temperature of water is 60 degrees celsius.

SUS304 Stainless Steel Tank

SUS304 stainless steel does better in resistance to alkali solution and most organic and inorganic acid than SUS201 or other SUS200 stainless steel series. However, SUS304 stainless steel has no resistance to solution with chloridions, such as hydrochloric acid, and hydrofluoric acid.

Note: Please don't use flammable, explosive or volatile cleaning solution.

A Seperate Power Switch and A Backup Fuse

A separate power switch can ensure a longer service-life, while the fuse in the power socket can prevent the ultrasonic cleaner from being damaged by an instantaneous over-high voltage, especially there is a backup fuse in the socket which can bing the ultrasonic cleaner back to work once the fuse in use is burnt by an instantaneous over-high voltage accidently.
