Dry ice is manufactured to perform different functions which includes cleaning. From residential to commercial environments, dry ice can be used to clean in a sustainable and cost-effective manner.

Here are the surprising cleaning benefits of dry ice:

For AC motors, the stator and rotor are the most critical parts, and these parts need to be cleaned and maintained often to keep a motor working smoothly.

Carbon deposits, debris, and other things like oil, grease, and paint chippings can clog and rust both stators and rotors over time. The longer this residue is allowed to accumulate, the more it might degrade efficiency and even cause breakdowns.

Using common household cleaners runs the risk of exposing the motor to harmful chemicals and accelerating corrosion. Manual cleaning methods, such as scrubbing or sandblasting, can further hasten the wear and tear on the components.

Therefore, it is recommended that you use only dry, non-abrasive techniques. As such, a stator and rotor are best cleaned with dry ice blasting.

Using a pressurised air stream, dry ice pellets measuring 3 millimeters in diameter are driven towards the surface to be cleaned. Upon impact, the dry ice sublimates, leaving a dry, clean surface.

When treating a surface with dry ice, thermal shock occurs due to the temperature difference between the ice and the surface. In doing so, the relationship between the two incompatible materials is broken.

In order to clean a surface, compressed air is used to accelerate pellets of dry ice to speeds of up to 300 meters per second before blasting them onto the surface. Impact from kinetic energy is the second step in the cleaning process.

When it comes to cleaning whole electric motors, stator or rotor windings, AC or DC, dry ice cleaning is considered to be the procedure that is the most efficient, safest and cost-effective.

Cleaning with non-conductive, non-abrasive, moisture-free dry ice is an effective method for removing winding contaminants such as grease, dried paper, dirt, dust and carbon.

After being cleaned with dry ice, the Mega-Ohm and PI tests reveal significant improvements in the windings of the motor, and the temperature at which they operate drops.

Below are some additional benefits to using dry ice blasting on rotors and motors:

There is no rubbing, scrubbing, or other form of friction involved. Because of this, there is a substantially lower chance that the components of the system will be damaged.

Dry ice blasting is a technique for removing muck and buildup that does not leave any residue behind, in contrast to other procedures that use particle matter, like sandblasting. As a result, this way of maintaining a stator and rotor is the one that is the quickest, the easiest and the cleanest.

Dry ice poses no threat to people, animals, or machinery and can therefore be used in a variety of settings. Because of this, it is an excellent choice for use in sensitive settings.
