Energy Conservation measures in compressed air system

• Keep the minimum possible range between load and unload pressure settings.             

• The compressor(s) with the highest part-load efficiency is placed in trim service to handle variations in load.

• Retrofit with variable speed drives in big compressors, say over 100 kW, to eliminate the ‘unloaded' running condition altogether.

• Reduce compressor delivery pressure, wherever possible, to save energy.  Reducing and controlling system pressure downstream of the primary receiver can reduce energy consumption, leakage, demand for new capacity, as well as cause less stress on components and operating equipment.

• Use blowers instead of compressed air to provide cooling, aspirating, blow guns, air lances, agitating, mixing, or to inflate packaging

• Provide extra air receivers at points of high cyclic-air demand which permits operation without extra compressor capacity.

• Pressure drop is the reduction in air pressure from the compressor to the actual point of use.  A properly designed system should have a pressure drop of below 10 percent of the compressor's discharge pressure.

• Eliminate inappropriate air users-Use brushes, blowers, or vacuum systems instead of compressed air to clean parts or remove debris

• Cooler air is denser and provides more mass for each compression cycle with no additional power use. Lower inlet air temperature will result in less compressor work.

•   Use outside air for cooling reciprocating and lubricant-free screw compressors when it is cooler than indoor air.
