This is a two-part article looking at factors impacting decisions on whether to use air or water-cooled air compressors. It also provides heat recovery guidelines for both situations. Part 2 will provide a review of alternative cooling water system options and their approximate operating costs.
To continue meeting demand for air compressors, Doosan Bobcat invested heavily in U.S. manufacturing facilities including its one-million-square-foot manufacturing operation in Statesville, North Carolina. The $70 million expansion of the facility amplified its operations, where it now employs 930 people in office and factory positions and manufactures its line of portable air compressors from 185 cfm to 1,600 cfm, in addition to other Bobcat products like compact tractors, generators, light towers and mini track loaders. It also assembles and stocks the expanding line of Doosan Bobcat industrial air compressors.
Over the last two decades, there has been a significant increase of manufacturing facilities deciding to produce their own nitrogen on-site, using compressed air systems and nitrogen generators. They are choosing on-site nitrogen generation, instead of purchasing and receiving deliveries of nitrogen by the cylinder or having a “Nitrogen Over the Fence” supplier.
A ‘Process’ application, is one where it’s all about controlling the contents of a vessel, pipeline, or chamber. What is the gas makeup inside the vessel? How much of it is in there? All means to control a chemical and/or thermodynamic reaction so that we add value to some base ingredients to convert them into a marketable product.
