The single dry ice particles are accelerated by the compressed air stream through the total length of the hose, it increasing the kinetic energy and the aggressiveness of the cleaning system. one hose is leading from the hopper to the applicator and there is a feeder system that feeds the dry ice particles and compressed air into that single hose. advantage of single-hose machines is an option of using a longer hose, which allows an operator to be further from the machine with little reduction in blast aggression. Single-hose system aggression is also ideally suiting for removing heavier build-up the dirt or for blasting at a vertical elevation where the machine is at a lower level than the blasting surface.
