Air Station Cuts Specific Power 30% at a Precision Maker in Anhui

The precision manufacturing facility in Anhui faced significant challenges in balancing energy supply and demand. The energy supply side — the distribution room, air compressor station and refrigeration station — was not efficiently matched with the energy demand side, the production workshops, so the air compressor station alone accounted for 35% of energy consumption. The station provided compressed air for four core production areas, with an instantaneous flow rate of 1100m³/min, making it a major energy consumer. Despite having experienced engineers and a dedicated operations team, the station's energy consumption remained high.

Equipment: SIND SILVERLUBE-VPM series PM VSD screw compressors

SIND partnered with the precision manufacturing facility in Anhui to implement a comprehensive energy-saving strategy. The solution included equipment upgrades, AI intelligent control, and optimised operations management. The equipment upgrades involved replacing old screw compressors with high-efficiency centrifugal compressors, and optimising the compressed air distribution network with pressure sensors. AI intelligent control was implemented to monitor and adjust the air supply based on real-time data, ensuring optimal energy efficiency. Operations management was streamlined with professional engineers providing on-site support, standardising processes, and making billing transparent.

The precision manufacturing facility in Anhui achieved a 30% reduction in specific power consumption within three years. The energy consumption per kilogram of gas decreased by 7% for the centrifugal compressors. The facility saved over 18 million kWh of electricity annually, reducing carbon emissions by 14,951 tons of CO2e. These improvements significantly reduced operational costs by 10% to 30%. The facility's efforts in adopting digital transformation and advanced technologies have led to a significant reduction in energy consumption and carbon emissions, positioning it as a national-level green factory.
