Ever-increasing demands regarding the cleanliness of component surfaces call for increasingly effective cleaning methods. With its innovative dry cleaning technology using a jet of CO2 snow, acp GmbH has developed an in-line process that is capable of removing particulate and filmy contamination (e.g. dust, ablation residues, flitter, flux residues, smoke residues from laser processes, oils, fingerprints, cutting emulsions, polishing paste, etc.) from almost any material in a gentle but effective manner. The process can be used not only to clean large surface areas but also to selectively remove contamination from tiny defined functional areas with the highest cleanliness requirements.
CO2 snow cleaning quattroClean™ Technology
Whether for use in connection with painting plastics, manufacturing precision mechatronic products, in electronics or the semiconductor or optical industry, in order to achieve high-quality results in coating, painting, joining or other processes, surfaces need to be free of particles, oils and grease.
The patented CO2 snow cleaning technology cleans sensitive component areas using a dry, environmentally-friendly, residue-free process. By utilising a supersonic cleaning jet, optimum cleaning results can be achieved with a minimum consumption of CO2.
Automation of CO2 snow cleaning
Together with the option of a direct supply of liquid CO2 these features make the process especially suitable for automated applications. We offer a wide variety of solutions, ranging from portable cleaning systems, such as the JetWorker, through ready-assembled cleaning modules, right up to fully-automated production platforms.
CO2 snow cleaning functional principles:
- Dissolving of filmy residues (solvent-free)
- Rinsing (increase in volume of approx. 500x during sublimation)
- Embrittlement of the contamination through rapid cooling
- Detachment due to the transmitted forces of pressure and shearing
CO2 snow cleaning advantages:
- Dry cleaning process
- Solvent free
- Cleaning is non-dependent on material
- Residue-free cleaning
- Reduction in costs
- Improves product quality and process efficiency
- Enables one-piece flow and lean-production
- Process fits well with the execution of the Smart Factory for Industry 4.0
- Environmentally-friendly and non-toxic
Thinking of the environment
Liquid CO2 is recovered as a by-product from the chemical industry and from biodigestors. Using CO2 as a cleaning agent replaces toxic cleaning agents. Kinder to you and the environment!
