Dry Ice Cleaning
The process works as follows:
Compacted dry ice particles (compressed recycled CO2 in its solid state) are accelerated in a stream of compressed air and used as an abrasive. Dry ice blasting consists of 3 phases.
The mechanical phase
This is the phase in which the dry ice particles accelerate in the air stream and make contact with the unwanted deposit, thereby removing it.
The thermal phase
This is the phase in which the dry ice particles reach a low temperature of -79 °C. This low temperature makes the deposit brittle. When the particles make contact with it, cracks appear in its surface and the deposit can easily be removed.
The sublimation phase
When the dry ice particles strike the surface, they sublimate from solid to gas. As a result, their volume expands by 700 times and the deposit ‘explodes’.
The use of dry ice cleaning has many advantages:
100% natural product
Dry ice cleaning is fully environmentally-friendly. No chemicals or solvents are used during the cleaning process. This means that there are no costs for the removal and storage of chemicals or solvents. Dry ice cleaning does not produce any extra waste substances. All that must be cleared is the contamination. This can be vacuumed or swept away.
Fast, efficient and thorough
Dry ice cleaning is a fast cleaning method. It is ideal for the removal of rust. This technique is also an excellent option when it comes to preparing machinery for audits.
Safe to use on machinery
Dry ice cleaning is a fully dry process because the dry ice consists of CO2 and therefore evaporates when it makes contact with the target surface. This is one of the reasons why it is ideal for cleaning electric motors and electrical, pneumatic or hydraulic components. Dry ice cleaning does not have a damaging abrasive effect. Surface cleaning is gentle because the use of steel brushes, spatulas, scrapers, and blasting materials like sand, glass or plastic is avoided. Many machines used in the food processing industry and medical and care sector cannot get wet under any circumstances. In such cases, this form of cleaning offers the ideal solution.
Lower cleaning wage expenses, lower equipment depreciation costs thanks to less wear, less downtime, more effective production time, no waste removal costs and no costs for storing chemicals or solvents all have a positive economic effect.
To sum it up, you can no longer put off making this innovative cleaning solution part of your company’s cleaning process.
