GREENER CLEANING

TO PROTECT US AND OUR WORLD

Cryogenic cleaning
This process involves directing a current of pressurized air containing frozen CO2 or dry ice over the surface of the part.
The effect is similar to sandblasting:
- Mechanical shock (projectile pressure)
- Thermal shock (ice cooled to 80°C)
- Sublimation (converting from solid to gaseous state)
Cryogenic cleaning uses only CO2. The technique is already used in several industrial processes but it will need to be analyzed and qualified on our products om prder to maintain the integrity of our coatings and substrates. The aim will be to testing the technique on our parts, accessories, modules and complete engines.
The results of all the tests carried out on specimens and parts show that cryogenic cleaning with optimised parameters does not alter any material or coating (paint, OAS, cadmium plating, etc.).
This process can be used on mechanical assemblies as well as on electrical accessories.
The process is currently being industrialised in our repair workshops.
