A dry ice blasting machine is a revolutionary blasting method that uses small, compact dry ice pellets as the blasting material. The dry ice pellets are accelerated in a jet of compressed air similar to that used in traditional blasting methods. Dry ice blasting is designed to replace high-pressure hosing and other traditional blasting methods that use materials such as sand, glass, and plastic as abrasive agents. In addition, however, a wide range of other cleaning methods that involve the use of hazardous chemicals, solvents, etc., can with advantage be replaced by dry ice blasting. The unique feature of dry ice as a blasting material is that it vaporizes on contact with the surface to be cleaned. Treated surfaces are therefore left dry and clean, without residues of detergents or blasting materials. As the process is completely dry and non-conductive, dry ice blasting can be used where other methods are unsuitable. For example, electric motors and equipment with electric, pneumatic or hydraulic components can be cleaned direct using dry ice blasting.
The system produces no waste products. Only the coating that has been removed remains to be disposed of, and this can usually be swept or vacuumed from the floor beneath the treated object. Dry ice blasting is ideal for removing coatings such as adhesives, varnish, oil, grease, coal dust, soot, mould release agents, and bitumen – to name but a few of the materials we remove daily using the process. Dry ice blasting will often allow a company’s production equipment to be cleaned while in operation without the need for dismantling and costly downtime. Dry ice blasting is non-abrasive, and surfaces are therefore treated gently. The system can thus be used on easily damaged surfaces like nickel, chromium, and soft aluminum. The process is dry, and no waste materials are produced. This means that cleaning can be carried out even during short production shutdowns.
What is the difference between a single hose and a Two hose (dual hose) ice blasting machine?
There are two basic types of dry ice blasting systems:
- Single-hose systems
- Dual-hose (venturi) systems
Single hose system, dry ice is mixed with compressed air in the machine itself. This allows the dry ice pellets to attain a higher velocity (kinetic energy) and thus provides greater cleaning effectiveness. In a two-hose system, dry ice pellets are sucked into the blasting gun through a venturi system. As the pellets are first mixed with compressed air in the blasting gun, their velocity is lower than in a one-hose system, and their cleaning effectiveness is thus lower.
In single-hose systems, there is one hose 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. The dry ice particles are then accelerated by the compressed air stream through the entire length of the hose, dramatically increasing their kinetic energy and the aggressiveness of the clean. A key advantage of single-hose machines is the 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 ideal for removing heavier build-up or for blasting at a vertical elevation where the machine is at a lower level than the blasting surface.
In dual hose systems, compressed air is supplied to the blast applicator through one hose, while dry ice is supplied through a second hose running from the applicator to the hopper. The passage of compressed air through the applicator creates a suction on the second hose that pulls the dry ice particles from the hopper into the compressed air stream at the applicator. The dry ice particles and compressed air are then blasted together. As the dry ice particles are only actually accelerated the length of the applicator by the compressed air, the dual hose system has a relatively small kinetic effect and offers a much less aggressive clean than single hose technology.

Two hose systems also have the following limitations for blasting :
- length of the hose is limited by the two-hose suction capability, which then limits how far away the blasting can take place from the machine
- limited aggression of the two-hose system will not allow for vertical blasting because the suction would also have to overcome gravity
- allowable diameter of two-hose nozzles is limited by the lower efficiency and impact velocity created by pulling particles into the nozzle by suction
