Abstract (en)
In a method of cleaning surfaces, especially surfaces of electric devices under voltage, using a dry ice method, a stream of compressed air is applied onto a cleaned surface at a safe distance. Before applying, the compressed air is dried to humidity of 0,008 - 0,0002 g/m 3 and then, is passed through a container with dry ice of the temperature from -70°C to -30°C and granulation from 1,5 to 5 mm. A set for cleaning surfaces comprises a nozzle embedded on a lance connected by a house with a dispensing device (6) of a dry ice and compressed air supplied by a compressor (2). Between the compressor (2) and the dispensing device (6) of dry ice there is mounted a dehumidifier (4) of compressed air connected by a hose (3) with the compressor (2) and by a second hose (5) with the dispensing device (6) of dry ice.
