In June of last year, the (International Promoting Council of Industrial Coating, IPCO) brought in the cleaning technology of the dry ice blast facility produced by the German company Karcher. It is conducting tests to remove grime and paint accumulated inside gas drying furnace in lines for painting for industrial use. If this technology were to go into full scale use, the painting industry could emerge as a new demand for dry ice blasting.

Conventional chamber cleaning first involves the use of hand tools such as Scotch Bright (file) and a spatula. After this in large, 30m type large furnaces, up to 100kg of solution are used each time, then applying adhered waste cloth and cleaners. All of this involves manual labor. Daily cleaning has been required up to now to prevent poor painting due to scrapings from the surface of the wall inside the furnace and to improve quality. However as this involves several workers per drying furnace, depending on the size, so that in reality this was carried out at the rate of once every 6 months.

In the case of dry ice blast cleaning, pretreatment is unnecessary and the belt conveyer inside the chamber is not dismantled. This means that blasting can be done while the facility is still operating. No new waste material arises either. It turns out that all that is left to be done is just to recovery of the old, scrapped off coating of paint. This results in a great reduction of time and labor expenses.
