At Lampo-Lab, trials on a coffee-machine heat exchanger used a manual Venturi sandblasting machine to remove deposits from channels and difficult surfaces without altering component geometry. Remove substantial limescale deposits from hard-to-reach areas while preserving aluminium geometry and surface characteristics. The operator needed precise, localised control. Tests identified suitable media and parameters. A blasting gun support held the jet in position, leaving both hands free to move the component accurately beneath it. Manual blasting, the tested medium and gun support enabled targeted treatment. The operator concentrated on moving the exchanger and controlling jet action in each area. The trials removed limescale and deposits without altering component geometry, leaving clean, uniform surfaces in difficult areas. Media and parameters were defined before machine configuration.
