Eliminate Air Leakage Calculations show that a tiny hole of 1 mm² under 7 bar pressure creates a leakage rate of approximately 1.5 L/s. Inspect all transmission pipelines and gas consumption points, especially joints and valves, and repair leakage points promptly.

Control Pressure Drop Install pressure gauges on pipeline sections to monitor pressure and inspect pressure loss in each pipeline segment; maintain problematic pipelines timely. Generally, the total pressure drop from the air compressor outlet to gas consumption points shall not exceed 1 bar. Under strict standards, the limit is 10% (0.7 bar). The typical pressure drop across refrigerated dryers and filters is 0.2 bar. Factories are recommended to adopt loop piping networks to balance gas pressure at all consumption points.

Match Pressure Setting with Demand of Pneumatic Equipment Evaluate pressure requirements of gas-consuming equipment, and lower the compressor discharge pressure as much as possible while guaranteeing normal production. Every 1 bar reduction in discharge pressure delivers roughly 7%~10% energy savings.

Rectify Irrational Compressed Air Usage Authoritative statistics indicate only around 10% of electric power consumed by air compressors is effectively utilized, while nearly 90% is lost as heat. Assess on-site pneumatic equipment to see if electric drives can serve as alternatives. Furthermore, compressed air shall never be used for routine cleaning.

Adopt Centralized Control System For a small number of compressors, one variable frequency air compressor can be used for pressure regulation. For multiple units, implement centralized coordinated control to avoid stepped rise of discharge pressure caused by inconsistent parameter settings of multiple compressors.

Regular Equipment Maintenance and Cleaning Improve heat dissipation of air compressors, enhance heat exchange efficiency of water-cooled or air-cooled heat exchangers, and maintain clean lubricating oil.

Waste Heat Recovery for Air Compressors Recover heat from the compressor oil circuit to produce hot water for production processes or domestic auxiliary facilities.

Retrofit or Replace Drying System New-generation drying equipment utilizes waste heat of compressed air to dehydrate compressed air, achieving an energy saving rate of over 80%.
