Compressed air is dried to prevent condensation and corrosion which can disrupt manufacturing processes and contaminate products. Water is the primary promotor of chemical reactions and physical erosion in compressed air systems. A myriad of desiccant dryer designs have been devised to provide “commercially dry” air, air having a dew point of -40°F or less, to prevent corrosion. Desiccant dryers use solid adsorbents in granule form to reduce the moisture content of compressed air.
Nuclear power plants produce electricity for people, business and industry. Electricity is produced in a similar fashion as fossil fuel (i.e., coal, oil, etc.) power plants, using steam to drive a turbines which spin an electrical generator, producing the electricity.
Industry standards serve a very important purpose for the end users of compressed air equipment. If the standards are well written, they can help to promote the equipment that they govern, as long as the equipment manufacturers properly apply and promote the standards.
Boeing Canada has replaced their onsite membrane style Nitrogen generator with a new more modern system with increased capacity and higher efficiency. As a result, the company is now using minimal amounts of expensive liquid Nitrogen, and has reduced the energy cost per unit of gas produced by 83%.
Compressed Air Practices interviewed Mark McKean (National Sales Manager) from Prevost Corporation.
Motor Coach Industries, headquartered in Schaumburg, Illinois, is the largest manufacturer of intercity tour coaches for the tour, charter, line-haul, scheduled service, commuter transit and conversion markets in the U.S. and Canada. The company operates a four screw-type air compressor system at its Clarence Avenue plant in Winnipeg. To maintain adequate system pressure at the plant, Motor Coach was forced to run all four compressors 24 hours a day, seven days a week.
New Flyer Industries is a Winnipeg based heavy duty bus manufacturer, supplying vehicles to the US and Canadian markets. The company specializes in vehicles with†alternative-fuel drives such as electric trolleys, gasoline-electric and diesel-electric hybrid vehicles; as well as standard diesel buses.
The NFPA 99 (National Fire Protection Agency) Standard for Healthcare Facilities (2005 Edition) is the current Code by which Healthcare facilities in the U.S. design their compressed air systems. The NFPA 99 Standard covers many requirements for medical gases, with compressed air being just a component of the Standard.
