In medium and large-scale manufacturing plants, multiple air compressors operating in parallel is a common configuration. However, many enterprises still rely on a rough management approach of “manual start-stop of individual units.” This often results in multiple machines running at full load during peak demand and partial-load operation during off-peak periods, leading not only to significant energy waste but also to pressure fluctuations that affect production stability.TECBELL’s multi-unit linkage control system enables intelligent and coordinated operation of air compressors. By automatically adjusting output based on real-time air demand, the system significantly reduces energy consumption and operating & maintenance costs.
Industry Background
Power battery manufacturing is a highly complex engineering system that relies heavily on automated equipment. From electrode preparation and cell assembly to electrolyte filling and final testing, each process requires stable, clean compressed air.However, in many factories, the compressed air systems that provide production power suffer from issues such as “insufficient quality” and “poor energy efficiency.” Traditional compressed air systems are characterized by high energy consumption, frequent pressure fluctuations, and excessive waste. These issues not only increase operating costs but also directly affect production stability and the final product qualification rate.Addressing compressed air system bottlenecks has become a critical step in enhancing manufacturing competitiveness.
Customer Requirements
The customer for this project is an enterprise specializing in the R&D, manufacturing, and sales of power batteries. With rapid capacity expansion and increasingly stringent quality requirements, the customer three core demands for the new compressed air system:
High Efficiency & Energy Saving
The compressed air system must feature fast and precise load-following capability to efficiently respond to periodic load fluctuations in processes such as electrode coating and winding. By matching air generation with actual air consumption in real time, the system fundamentally reduces unloaded energy loss and delivers substantial energy-saving results.
Clean Compressed Air
Provide stable, 100% oil-free compressed air to meet the strict air purity requirements of battery production, ensuring zero contamination risk and safeguarding product quality.
Reliable Operation
The system must adopt a high-reliability design and integrate intelligent predictive maintenance functions to minimize unplanned downtime and reduce total lifecycle costs.
Solution
TECBELL delivers not a single piece of equipment, but an integrated, efficient, stable, and intelligent system solution.The core configuration consists of three 700 kW centrifugal air compressors operating in coordination with two 315 kW dry oil-free screw compressors, providing a total air capacity of 510 m³/min, fully meeting the large-scale air demand of power battery manufacturing.
Coordinated Operation with Precise Air Demand Matching
The system adopts an optimized combination in which centrifugal compressors handle the base load, while screw compressors regulate load fluctuations.Centrifugal compressors provide stable base air supply with high efficiency and constant pressure characteristics. Variable-speed dry oil-free screw compressors respond in real time to load changes, enabling fast and precise airflow adjustment.This operating mode ensures continuous air supply while minimizing energy losses caused by unloading or overloading.
High Airflow Capacity with 100% Oil-Free Air Supply
With a strong supply capacity of 510 m³/min, the system easily supports high-load equipment such as electrode preparation and cell assembly lines, ensuring continuous and stable production.At the same time, dry oil-free screw technology guarantees 100% oil-free compressed air, completely eliminating the risk of oil contamination and fully meeting the stringent cleanliness requirements of battery manufacturing and precision assembly processes.
Intelligent Operation & Predictive Maintenance
The compressed air station is equipped with an intelligent centralized control system, integrating remote monitoring and predictive maintenance functions.By continuously monitoring equipment operating status and issuing early warnings for potential faults, the system effectively reduces failure rates, maximizes equipment utilization, and optimizes energy efficiency.
Through comprehensive reductions in energy consumption and maintenance costs, the system helps enterprises achieve a virtuous cycle of “one-time investment, long-term returns,” with annual electricity savings reaching millions of RMB.
TECBELL remains committed to driving high-quality development in the manufacturing industry through technological innovation. Looking ahead, TECBELL will continue to deepen its expertise in intelligent compressed air systems, continuously optimizing product performance and energy efficiency.By providing power battery manufacturers with safe, reliable, green, and sustainable compressed air solutions, TECBELL helps customers gain a competitive edge in an increasingly demanding market and jointly advance the industry toward a more efficient, low-carbon, and sustainable future.
