Cold Jet, Loveland, Ohio, introduced the latest model in its SDI series of dry-ice mold-cleaning machines at NPE2012. The unit can use either shaved ice or pellets. Operators can convert from one to the other in less than 10 min without any change parts. Cold Jet claims the SDI series is the first industrial dry-ice cleaning machine to use single-hose technology across the entire dry-ice cleaning-media spectrum, which in turn enhances flexibility to perform delicate or more aggressive cleaning as needed with a single machine. The machine accepts a standard 90-lb block or 50 lb of pellets, and can run 50 to 250 cfm.
