Expert Mold Inspections & Environmental Testing in Centre Wellington, ON

Sandblasting is like using an ice pick, whereas dry ice blasting is like using a spatula. Sand cuts or chisels away the contaminant, while dry ice lifts it away.

The range of cleaning applications for dry ice is phenomenal and is easily demonstrated in just a small sampling of our customer base: core boxes for Ford; delicate wiring in copy machines for Xerox; conveyors for Nabisco; tire molds for Michelin; dry ice blasting shines in cleaning production equipment online, because it eliminates the need for masking, cool down and disassembly. Users minimize downtime which maximizes production efficiency. We have achieved outstanding results cleaning production equipment for foundries, molded rubber producers, food processors, printers, and the semiconductor industry. Dry ice blasting is also widely used in the nuclear industry for decontamination. Wherever waste volume or health risks are a concern, the viability of dry ice should be examined. Because dry ice disappears on impact, it creates no additional waste. Competing processes such as grit blasting or solvents often present disposal problems or health hazards.

The process cleans best hot. Most contaminants have weaker adhesive strength when hot. In many applications, you may be able to clean three to five times faster hot than cold. In addition, because dry ice sublimates on impact, entrapment of the blasting media is not an issue. Grit entrapment is an important reason those who clean with sand, walnut shells, or other grit media cannot clean online.

In a two-hose system, the dry ice travels in one hose and the high-pressure air in another. The two are not mixed until just before the pellets exit the end of the nozzle. The primary advantage of a two-hose system is simplicity. In a one-hose system the pellets and air are mixed together in one hose at an air lock and travel the complete length of the hose. Although generally a one-hose system uses more ice, in the Triventek Triblast-3 one-hose system, ice consumption can be adjusted to permit very low ice consumption. In areas where there is a substantial thickness of contaminant the single hose system can permit added blasting aggression and faster cleaning. With the Triblast-3 system, customers receive the advantages of simple design, ease of maintenance, and adjustability all in one unit.

One person can easily roll all the Triventek portable blaster around the shop floor without any special equipment. The Triblast-2 is small enough to carry upstairs for complete blasting freedom.
