FAQ:

What is ultrasonic?

Ultrasonic is sound generated beyond human audible level. In real life, high pitch sound is created by high frequency, and alternatively, the low and base tone is created by low frequency. Frequencies above 16 kHz in general are being considered as ultrasonic. Typical ultrasonic frequencies used for cleaning purpose are from 20 kHz to 80 kHz.

 

How a sound can clean?

A physical effect called "cavitations" ultrasonic generates in liquid is responsible for the cleaning process. Cavitations form when ultrasonic travels through liquid. When a sound wave travels through water, it stretches and compresses the water medium to transmit sound. When the amplitude of such sound wave increases to a level when water can't hold the stretch, the sound literally tears the water apart, and millions of vacuumed "bubbles" are formed under such negative pressure.
The sizes of vacuumed "bubbles" increase until their equilibrium are reached; the "bubbles" then rapidly compress by water and create millions of tiny liquid jets.
The jet actions release tremendous amount of energy stored within vacuumed bubbles; each "bubble" is estimated to have a temperature of more then 5000 degree Celsius and a pressure of more than 10,000 PSI at molecular level when such implosion takes place. The huge amount of pressure releases at each "bubble" provides an ideal physical phenomenon responsible for the effective cleaning action ultrasonic cleaner offers.

 

Ultrasonic cleans cracks

Cavitation takes place everywhere liquid can reach; during the cleaning process, the article being cleaned is submerged into water or cleaning solution, millions of micro-sized "bubbles" created by ultrasonic are capable of reaching into fine trends or cracks to clean.

 

Ultrasonic Cleaning: frequency higher the better?

The frequency of an ultrasonic cleaning device has nothing to do with the cleaning power. The ideal cleaning frequency is determined by what is going to be cleaned. Simply speaking, the higher the frequency the more capable it is to remove smaller particles.

 

Ultrasonic, the answer to environmental-friendly cleaning for home

Although ultrasonic has been an effective industries' cleaning solution for decades, environmentally unfriendly, chemical-based cleaning method is still widely used at home. Codyson believes ultrasonic will be the next generation cleaning solution for home.
