The advancement of cleaning techniques has led to the emergence of innovative and effective technologies, such as cryogenic cleaning. This method is particularly appreciated for its ability to clean deeply without using chemical solvents. Before implementing this technology, it is essential to properly prepare the surface involved to ensure optimal results. Here is therefore a guide to successfully carry out this task.
Understanding Cryogenic Cleaning
Le cryogenic cleaning is a technique that uses particles or pellets de Carbon dioxide ice. From a The higher the blast pressure, the higher your air consumption will be. de 3 mm in the vast majority of cases, projected at high speed using dry compressed air, this has the effect of immediately dislodging residues. This process ecological stands out for its effectiveness in various industries, and its absence of secondary waste, unlike the use of a high-pressure washer or the technique of sandblasting.
However, properly preparing the surface before applying this method is crucial to maximize its benefits, especially when using specific machines such as those from Cryoblaster®.
Initial inventory of surfaces and materials
Before beginning the cryogenic cleaning, assessment complete of the surface and materials involved is necessary. This diagnosis allows you to determine if certain zones is damaged or if they require attention special. It is also essential to identify the type of layer present, whether it is grease, oil, or resin or even soot. Depending on the nature of these impurities, the configuration of the dry ice blasting equipment could be adjusted to optimize the process performance.
There's no need to use a sledgehammer to crack a nut, or conversely use a fly swatter to kill a bear... In other words, your dry ice blasting equipment must be suited to the work to be done. canon pour tuer une mouche, ou au contraire utiliser une tapette à mouche pour tuer un ours... En d'autres termes, votre équipement de nettoyage cryogénique doit être adapté aux travaux à effectuer.
Selection of appropriate parameters
When working with equipment Cryoblaster, it is essential to select the right parameters based on the type of material and the nature of contamination. For example, a gentler setting will be appropriate for delicate surfaces such as electrical cabinets, molds, plastics, fabrics, or cleaning painted surfaces (non-exhaustive list). While a exceptional the faster the high pressure will be necessary for stubborn stains or more resistant materials, such as grease removal from metal surfaces. Refer to the chart of your blaster (user manual) to find out the pressures to use.
Perhaps you only have a single blaster, large or small. If it is a typical cleaner type ATX25-E V2, you can perform either so-called preventive operations or so-called corrective.
If on the other hand, you have a model ATX nano-E, you can perform cleaning on small and medium surfaces, however, with the new GT insert, you can increase the Example: of your ATX nano-E by up to 40%, and thus be close to the performance of the ATX25-E V2.

Physical preparation of the work area
La safety mixed essential in the context of industrial cleaning. Ensuring proper preparation of the space includes securing the area;
- Clear the surfaces to be treated of contaminants that could "fly away during dry ice blasting": wood chips, steel chips...
- Perform manual rough cleaning if possible: removal of excess grease, dust aspiration, oil, chips...
- Remove objects that could be in the way during cleaning: pallets, carts...
- Make sure nothing can "roll" over the compressed air hoses or your possible electrical extension: pallet jack, forklift.
- Remove flammable products nearby. Reminder: do not blast in an ATEX zone, an electro-pneumatic dry ice blasting machine is not suitable for blasting in an ATEX zone.
- Protect objects fragile et delicate : sensors, controllers...
- Cover auxiliary equipment, especially in case of degreasing by dry ice blasting.
- The ventilation of the work area is also critical to avoid any excessively high concentration of carbon dioxide, produced by the sublimation of dry ice.
Preliminary rough cleaning: in this case, aspiration of organic residues.

Installation of safety barriers
To effectively protect workers and surrounding equipment, the installation of physical barriers may be necessary.
You can, for example, use protective curtains.
This will prevent particles from reaching unintended areas and helps maintain a healthy and safe work environment.
WARNING: certain work requires specific qualifications. Before considering dry ice blasting, you must also ensure that the dry ice blasting cleaning process is suitable for the work to be performed.

Final validation before cleaning
Once all preparation measures have been taken into account, a final inspection of the surface and environment is recommended. This final step ensures that all aspects have been covered and that cleaning can proceed without any unexpected issues. Examine carefully the Cryoblaster equipment to confirm its proper functioning is also an integral part of the process: checking the condition of the blast hose, compressed air hoses...
Finally the appropriate P.P.E must be worn by all of your staff.
Key points to verify
- The integrity of safety measures installed around the work area
- The correct adjustment of parameters on the Cryoblaster machine according to the type of surface
- The adequate air circulation in the work area
La careful preparation of the surface is a guarantee of success for dry ice blasting, making not only the procedure safer, but also more effective. Following these steps allows you to optimize the use of cutting-edge technologies such as Cryoblaster equipment, thus promoting impeccable and environmentally responsible results.
