Abstract

A tube (8) to be cleaned is fitted with an end cap (7) arranged to take a hollow rod (6) with a scraping head (9) fitted with a water discharge spray. The loosened dirt and scale is discharged through a tube (10) into the tank (2) which contains a filter element (15). The filtered water is recirculated by means of the high pressure pump (1) which recirculates the water through the tube. The space above the recirculation tank is kept under slight vacuum by the extractor (14) which draws air from the tank (12) connected to the water tank by the pipe (11).
