Degreasing with dry ice blasting: An innovative and eco-friendly solution
Degreasing with dry ice blasting is an innovative technique that uses dry ice to effectively clean and degrease various surfaces. In this article, we will examine the advantages of this degreasing method, as well as how it works and its areas of application.
It is an industrial stripping and cleaning process by projection of
- Industry: industry
- Treatment purpose : machine tools
- Equipment used : ATX80 replaced by ATX25-E V2
Le cryogenic cleaning is a cold stripping process based on projecting dry ice particles onto surfaces to be cleaned. These particles are obtained by solidifying gaseous CO2 at very low temperature (-78°C).
The projection of pellets of Carbon dioxide ice is performed using a cryogenic blaster, clean and dry compressed air, and a projection gun equipped with a supersonic or subsonic nozzle.
During dry ice blasting degreasing operations, 85% of services are performed at pressures of 5-6 bars, for compressed air volumes of 3 500 to 5000 l/min (depends on pressure and nozzle type).
How dry ice blasting degreasing works
The dry ice blasting degreasing technique is based on a combination of three effects:
- The thermal effect: The thermal shock caused by the impact of dry ice particles on the surface weakens the layer of dirt or grease adhering to it, making removal easier.
- The mechanical effect: Particles hit the surface at high speed, creating an effect similar to sandblasting or high-pressure water projection, which helps break the bonds between impurities and the surface.
- The sublimation effect: Upon contact with surfaces to be cleaned, dry ice particles sublimate (that is, they transition directly from solid to gaseous state), causing rapid expansion that lifts off and removes adhering residue.

Advantages of dry ice blasting degreasing
This degreasing process offers several advantages, such as:
-
- Eco-friendly cleaning: Dry ice blasting does not use chemicals or solvents harmful to the environment. Additionally, it generates very little secondary waste, as dry ice particles sublime into carbon dioxide, a naturally occurring harmless gas present in the atmosphere.
- An effective and fast solution: Dry ice blasting delivers excellent results even on heavily soiled surfaces. It also allows work in hard-to-reach areas thanks to the flexibility and precision of its projection nozzle.
- Non-abrasive and safe treatment: Unlike traditional sandblasting or shot blasting methods, dry ice blasting does not cause wear or deterioration of treated surfaces. Additionally, there is no need to disassemble equipment to perform cleaning, which limits damage risks and reduces downtime.
- Economic savings: The high efficiency of dry ice blasting can significantly reduce costs related to labor, waste, and equipment downtime.

Applications for dry ice blasting degreasing
Dry ice blasting can be used across a wide range of industrial and commercial sectors. Among the main applications are:
Maintenance and renovation of industrial equipment
This technique is particularly suitable for regular maintenance of machine tools, production equipment, motors, and other mechanical components. It enables the removal and elimination of grease deposits, oils, paint residue, dust, and other contaminants without damaging equipment or sensitive parts.
Cleaning and stripping of resistant surfaces
Dry ice projection is highly effective for cleaning and stripping floors clogged with grease, cement, adhesives, or paint. This environmentally responsible process offers an attractive alternative to chemical or mechanical stripping, such as shot blasting.
Decontamination and sanitization
Finally, this degreasing method can also be used in sanitization or decontamination work in professional facilities, such as industrial kitchens, cold storage rooms, laboratories, or food processing plants.
In summary, degreasing with dry ice blasting is a modern and innovative technique offering numerous advantages in terms of efficiency, speed, and environmental impact. It finds its place across multiple sectors, allowing each industry to benefit from the advantages offered by this revolutionary cleaning method.
