1.4 CLEANING WITH DRY ICE
1.4.1 Cleaning in the industry
In industrial processes pollution, impurities of all kinds, adhesion of contaminants on
machines, casting molds etc. in different concentrations do exist and can have impact
on the environment. The reliability of production related equipment, the quality of the
products and the safety for personnel are very important issues.
Plant managers and all other personnel in charge are therefore looking worldwide for
new cleaning technologies which are quality improving, cost saving and at the same
time environmentally-safe. In today's world the classical cleaning methods don’t always
meet the cleaning needs or have considerable drawbacks.
Some examples:
• High pressure cleaning and the use of solvents and other toxic chemicals increase
disposal costs dramatically.
• Grit blasting has its limitations because it is abrasive and there is always danger of
grit entrapment in moving parts.
• Tedious manual labour (i.e. scraping, scrubbing,…) results in a lot of man-hours and
is thus very expensive.
Cleaning with dry ice offers you a perfect, environmentally-friendly alternative.
1.4.2 The technology
The ASCOJET uses little pellets of carbon dioxide as blasting media. Liquid carbon
dioxide (CO
2
) is expanded in a production unit into carbonic snow which is extruded
under high pressure through a die. That way we produce hard and identical shaped
CO
2
pellets (approx. 0.12'' (3 mm) Ø). The dry ice pellet has a temperature of approx.
-110.2 °F (- 79 °C) and has a very special feature.
