For more than a decade, Calnetix Technologies has been at the forefront of turboexpander technology, designing, implementing and manufacturing some of the most innovative solutions for expanders across many industries. Calnetix was the first to bring a self-contained, fully integrated expander solution for industrial waste heat recovery to market and subsequently licensed the technology to GE and other OEMs. Since then, Calnetix has developed other turboexpander solutions for oil and gas and industrial applications, including cryogenic fluids, such as hydrogen, to broaden the market impact of its technology. Calnetix's subsidiary company Sapphire Technologies' turboexpander is hermetically sealed and utilizes non-contact magnetic bearings to eliminate the need for lubrication. In addition, special encapsulation and canning technologies enable our products to be cooled by corrosive process fluids.
