The maintenance costs are negligibly low as the CO2 snow blasting machines do not have any maintenance parts. The working parts which need to be replaced are kept to a minimum. We have automated systems in operation that have already been running more than 10,000 operating hours without failure. There is no wear on nozzles and hoses. We do recommend, as far as possible, to have every CO2 snow blasting machine checked by us once a year. For cost accounting purposes, generally accepted annual maintenance costs of, for example, 1 % of the investment costs should be accounted for.
