Nitrogen, an inert gas comprising 79% of the atmosphere, can be distilled from ordinary air. However, companies that use this product in their everyday operations know that it’s not quite that simple and much more expensive than the stuff we breathe. The primary means of obtaining nitrogen for industrial use is to transport it onsite in liquid form, which must be shipped and stored at cryogenic temperatures. But, really, what’s the point of turning nitrogen into liquid for shipping, transporting it to where it’s used, and then turning it back into gas?
The concept offers new possibilities for generating positive pressure or vacuum in a variety of applications. “By applying screw compressor technology to low-pressure air compression, we’ve greatly improved efficiency,” said Pierre Noack, President and CEO of Aerzen USA. The Delta Hybrid has seven patents or patent applications, making it one of the most innovative products in compression technology.
