Comparison with other cleaning methods
The need for improved productivity and cost efficiency, more stringent environmental protection requirements and, last but not least, safety of staff performing industrial cleaning and maintenance works today require the deployment of more advanced technology.
As a method able to satisfy all those expectations, dry ice cleaning is becoming a prominent alternative to conventional cleaning. Dry ice blasting of machine parts brings significant time saving since no disassembling and reassembling works are needed.
Advantages of dry ice cleaning
Using only non-toxic carbon dioxide and compressed air, dry ice cleaning technology is absolutely environmentally friendly and well suited for food industry applications. No hazardous chemicals are released during the cleaning process – a fact that significantly contributes to the protection of employee’s health.
Dry ice blasting minimises the disassembling and reassembling of machine parts and thus substantially reduces downtimes and outages. Another cost saving comes from elimination of the expensive use, removal and disposal of chemical preparations.
Dry ice pellets immediately vaporise (sublimate) in the cleaning process. Therefore, no secondary waste remains after the cleaning; only the removed dirt that is easy to sweep or vacuum-clean. As dry ice is non-conductive, it is suitable for the cleaning of electrical installations.
Dry ice has ideal non-abrasive properties. It perfectly removes dirt while being mild to surfaces and leaving them undamaged.
Cleaning with toxic solvents
Solvents are subject to strict requirements for special disposal, or even post-disposal treatment.
Halogenated carbohydrates as well as other cleaning substances have harmful effects on human health and on the environment.
The use of toxic solvents is mostly restricted by law!
The use of dry ice is not subject to any legal restrictions.
with glass beads or plastic granules
The abrasive elements (glass beads or granules) used in cleaning damage the surfaces being cleaned and thus impair the durability of parts. Dry ice pellets are non-abrasive and absolutely mild to surfaces.
Persisting blasting medium residues may significantly disturb the course of production. Since dry ice pellets immediately vaporise, this risk is eliminated.
Secondary waste from blasting requires special disposal, and often even costly treatment. The dry ice cleaning process does not generate any secondary waste since dry ice immediately sublimates.
High-pressure water jet cleaning
High-pressure water jet cleaning is damaging to surfaces being cleaned.
Dry ice pellets are non-abrasive and non-harmful to surfaces.
Water jet cleaning is unsuitable for electrical installations.
Dry ice is non-conductive and as such, it is suitable for the cleaning of electrical systems and installations.
Water and removed dirt must be separated for disposal.
The dry ice cleaning process does not generate any secondary waste.
Cleaned areas need prolonged times to dry out.
Dry ice cleaning is a dry process, which significantly reduces downtimes.
