Book Description

Compressed air has many applications in industry. Delivering compressed air to a manufacturing facility is an expensive operation and it requires costly equipment that consumes significant amounts of electricity and needs frequent maintenance. Roughly 80 to 90 percent of the electricity used to operate compressed air systems is converted to low-temperature waste heat. This lost energy can quickly add up, each year costing individual facilities as much as double the purchase and installation cost (first-cost) of the entire system. The ideal time to think about your compressed air system is before it is installed.Air Compressors deserve independent treatment due to many reasons. There is a wider choice of different types of compressor designs each operating at different efficiencies and suitable for specific application. The type of compressor decided upon has direct implications on the lifetime energy costs. Also the decision as to a single compressor of large capacity versus multi-compressor installation where each compressor has a smaller capacity than the demand influences the possible energy savings considerably. This 6 -hour Quick Book Course provides comprehensive information on the compressed air systems. This course is relevant to anyone needing to know more about compressed air production and use, relevant health and safety issues, legislation and energy efficiency. Previous knowledge of the subject is not required.The book includes a multiple type quiz comprising 30 questions at the end.
