Dry-ice blasting is nonabrasive, non-conductive, nonflammable, and non-toxic. Dry-ice blasting is an efficient [3] [verification needed] cleaning method. Dry ice is made of reclaimed carbon dioxide that is produced from other industrial processes, and is an approved media by the EPA, FDA and USDA. It also reduces or eliminates employee exposure ...

Pumpable ice can be produced in one of two ways: either by mixing crushed ice with a liquid or by freezing water within a liquid. The primary way is to manufacture commonly used forms of crystal solid ice, such as plate, tube, shell or flake ice, by crushing and mixing it with water. This mixture of different ice concentrations and particle
Illustration of an ice storage air conditioning unit in production. Ice storage air conditioning is the process of using ice for thermal energy storage. The process can reduce energy used for cooling during times of peak electrical demand. [1] Alternative power sources such as solar can also use the technology to store energy for later use. [1]
His 1856 patent was for a vapour-compression system using ether, alcohol, or ammonia.
