To be fair, that stuff is not so great for the environment not to mention it's a consumable so not so great on the wallet eithe, it's best to look at alternatives. For actual dusting then use an air compressor. For freeze testing components, suppose a freezer could work. If you want to target it I guess some kind of air hose that sucks air from a freezer at high velocity? Either way anything beats pumping ozone depleting and/or greenhouse gases in the air.
