ACP Systems AG is the first manufacturer of a non-wet chemical cleaning technology to receive the "Green Screen" certificate for cleaners and degreasers from Clean Production Action for its QuattroClean snow blasting technology in combination with CO2 gas from Linde. Green Screen is a globally recognized tool for evaluating and benchmarking chemicals based on their hazards. With the certificate, Clean Production Action (CPA) has created a benchmark specifically for cleaning media used as process chemicals in manufacturing. The focus is on the electronics industry. The background is the IPC-1402 - Standard for Green Cleaners Used in Electronics Manufacturing, jointly developed by the IPC (Association Connecting Electronics Industries), Apple and other international companies, which has been available since mid-2022. It defines the criteria that a "green" cleaner must meet in the electronics industry. The certification ensures that products tested by an independent organization according to scientifically sound and freely accessible criteria are free of PFAS (perfluorinated and polyfluorinated alkyl compounds) and other chemicals of concern. The test limits are 100 ppm. In the scalable QuattroClean snowblasting technology, recycled liquid carbon dioxide produced by chemical manufacturing processes and biomass energy generation is passed through a dual-substance annular nozzle. As it emerges, the CO2 expands to form fine snow particles, which are bundled and directed at the surface to be cleaned by a jacket jet of compressed air at supersonic speed. In the process, the jet unfolds four mechanisms of action that reliably remove particulate contamination down to the sub-micrometer range and filmic contamination. The process is used in the electronics and, semiconductor industry and communications technology as well as in medical and pharmaceutical technology, battery and fuel cell production, microsystems technology and other industries.
