In terms of electrical power usage and direct electrical power costs, the air compressor installation is probably the highest and most inefficient in terms of energy usage. 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 manufacturers as much as double the purchase and installation cost (first-cost) of the entire system.

Most manufacturing facilities use compressed air for at least some functions; for many plants, energy for compressed air systems can account for up to 35% of the total electrical power billing of a facility. Over 15% of total motor energy in the industrial sector goes to producing compressed air, yet compressed air systems are inherently inefficient, producing only one unit of useful work for every 8 units of energy input. It is obvious that the electrical costs of your particular installation need to be fully understood.

Energy efficiency measures can achieve significant energy savings, as high as 50 percent in some cases. Because of expensive operating costs, improving the energy efficiency of compressed air systems often payback investment in short time.

This six-hour course explains how the selection, control and maintenance of compressed air plant can improve energy efficiency and reduce running costs. It is applicable to mechanical engineers, energy auditors, facility managers, operation and maintenance personal and others in the design and renovation of facilities.
