The acp - advanced clean production GmbH is worldwide the only provider of cleaning systems based on an innovative CO2 Snow-Jet Cleaning Process. The specific characteristics of this cleaning process are approved to new areas of application in different fields of technology. Such systems are able to be easily adapted on various production environments.

CO2 Snow-Jet Cleaning systems use solid CO2 ice crystals as a jet medium. With its combination of mechanical, thermal and chemical properties, CO2 snow is able to gently detach and remove a whole variety of surface contamination. Developed at the Fraunhofer IPA in Stuttgart, Germany, the sublimation-impulse technique is the most efficient process to date for cleaning with CO2 snow worldwide.

As the liquid CO2 expands at the nozzle outlet, CO2 snow is formed which is accelerated to supersonic speed using a compressed-air jacketed jet and blasted onto the surface to be cleaned. The CO2 snow cleans gently, is dry, residue-free and suitable for use for a wide variety of materials and material combinations. CO2 gas is non-flammable, non-corrosive, non-toxic and environmentally-friendly.

The CO2 Snow-Jet Cleaning technique can be integrated into a wide variety of cleaning systems.

Dry cleaning process

Non-abrasive

Liquid CO2 supply

Environmentally-friendly and non-toxic

Cleaning is material non-dependent

Residue-free cleaning

The CO2 snow-jet nozzles designed by acp - advanced clean production GmbH have been developed for a broad range of application. Nozzles with a dot-shaped jet enable functional surfaces, e.g. bonding and sealing surfaces, welded seams, etc., to be cleaned in a targeted and selective way without having to clean the complete part. Particularly small nozzles have also been designed for cleaning areas which are difficult to access.

Nozzle arrays and flat nozzles are available for cleaning larger areas. The advantages of the CO2 snow-jet cleaning technique are, that it is environmentally friendly, residue free, solvent-free, and can be used in a cost optimised way to clean large delicate surfaces, e.g. plastic components before application of paint.
