Atlas Copco is committed to improving the energy efficiency of air compressor stations in the industry, in addition to unremittingly improving the energy efficiency of its products. Energy-saving of compressed air system can not only reduce the manufacturing cost and save money for enterprises, but also help enterprises realize the value-added of carbon assets. Since the group standard of CGMA 033001-2018, approved by China General Machinery Industry Association, was officially implemented on January 1, 2019, Atlas Copco has successively provided first-class energy-efficient air compression station energy-saving products for enterprises from different industries. So far, 14 first-class station buildings and one second-class station building have been certified.
Next, let’s review Atlas Copco’s first-class energy-efficient air compressor station house series solutions through some cases in different industries ~

The first class I energy-efficient compressed air station in PCB industry in China
From August 12 to August 13, 2021, Hefei General Mechanical and Electrical Products Testing Institute Co., Ltd. conducted a 24-hour measurement on the PCB multi-layer board air compression station of E building in Yidun. After 24-hour continuous measurement and statistics, the transmission efficiency of the PCB multilayer circuit board air compressor station in E building of Yidun is as high as 58.2%, which meets the requirements of the first-class energy-efficient air compressor station and is superior to the first-class index of 5.7%.
Atlas Copco provided the product combination of ZH710 high efficiency centrifuge and ND2000 compressed heat zero gas consumption drum dryer in this project. As the standard configuration of the first-class energy efficiency station building, ZH+ND can easily achieve the first-class energy efficiency index.
Dare to be the best in the world # Fuzhou Textile Industry # Class I energy-efficient compressed air station
Fuzhou is a textile town with many textile enterprises, and the textile industry is also a big energy consumer. The listing of the first-class energy-efficient station buildings of Fujian Wanhong Textile Co., Ltd. and Fujian Changle Yongde Textile Co., Ltd. has a strong role in energy-saving demonstration and promotion, which can vigorously promote the energy-saving and emission reduction work of the whole industry. # Fujian Textile Co., Ltd Using Atlas Copco’s professional product chain, we choose the configuration of efficient centrifugal compressor+rotary drum compression heat dryer to provide customers with the overall solution.
After 24-hour continuous measurement and statistics, the transmission efficiency rate of Fujian Wanhong Textile No.1 air compressor station is as high as 57.4%, which meets the requirements of the first-class energy-efficient air compressor station, and is superior to the first-class index of 4.9%. The transmission efficiency rate of Fujian Wanhong Textile No.2 air compressor station is as high as 59.5%, which meets the requirements of the first-class energy-efficient air compressor station and is superior to the first-class index of 4.5%. # Fujian Changle Textile Co., Ltd. In 2020, Yongde Textile invited suppliers to make a systematic analysis and comparison between the existing system and the actual gas demand at present, and successfully transformed the past five-level energy efficiency station building into the first-level energy efficiency station building.
Atlas Copco independently developed and designed the unique heat exchanger technology of environmentally friendly refrigerant freezing dryer, which ensures low pressure drop and low energy consumption. Combined with a series of energy-saving functions, it can reduce carbon emissions and operating costs. Before the transformation, the annual electricity consumption of customers was 3,168,400 kWh, after the transformation, the annual electricity consumption was 2,152,500 kWh, and the energy saving rate was as high as 32%. At the same time, the installed heat recovery device provides customers with 24 tons of hot water every day for free.

The first class I energy-efficient compressed air station in lithium battery industry # New Energy Technology Co., Ltd. # Industry keywords: lithium battery
Due to the expansion of production in ningde new energy and the low efficiency of old equipment, engineers Atlas Copco were invited to discuss the preliminary plan, and finally it was decided to add centrifuges and matching compression heat zero gas consumption energy-saving suction dryers to replace some old oil-injection screw compressors of other brands to improve the level of energy efficiency.
The actual demand air compressor is 240m³/min, and the zero gas consumption compression heat suction dryer needs ≥ 260m/min (the required pressure is reduced, the floor space is small) and the matching precision filter. The specific process gas is divided into three steps to realize the current production demand: First, adjust the gas consumption, use the old equipment, and use the old oil injection screw to balance the gas volume; Secondly, 100 m/min is used to replace the old oil injection screw machine with high energy consumption; Third, expand the capacity of 140m³/min production line to increase the new gas consumption.
Finally, it was appraised by Hefei General Mechanical and Electrical Products Testing Institute, realizing a leap in energy efficiency utilization quality of compressed air. It is wise to successfully replace the backward compressor and dryer through Atlas Copco’s energy consumption measurement and comparison, and it is also deserved that the project will eventually become the first-class energy efficiency station building in lithium battery industry. First-class energy-efficient compressed air station in glass industry # Fujian Automobile Glass Industry Co., Ltd. # Industry keywords: automotive glass Fujian Automobile Glass Industry Co., Ltd. wants to transform the original air compressor station building in order to reduce the energy consumption of production gas.
Atlas Copco Engineering Department went to the site, made some series of tests on the flow rate and power consumption of the original equipment, and finally decided to replace the original micro-oil screw air compressor with centrifuge+air dryer to realize centralized air supply for production. This scheme can not only improve the energy efficiency of the air compressor station building, and help improve the production efficiency, but also reduce the standby cost and production cost. In addition, the designed waste heat recovery system can shorten the investment return period of the project to one year, helping to further reduce the enterprise cost. Finally, appraised by Hefei General Mechanical and Electrical Products Testing Institute, the comprehensive efficiency rate of air compressor station building reached 60.6%, which was 3.1% higher than the first-class energy efficiency index.
