Against the backdrop of the high-end energy-saving air compressor market being dominated by foreign brands for a long time, domestic brands are rapidly rising with technological innovation and localized service advantages. Recently, Shanghai SaZhen Compressor Co., Ltd. announced that its compressed air station, built for a large manufacturing enterprise, has successfully passed the certification of an authoritative organization and been listed as a "Level 1 Energy Efficiency Compressed Air Station", achieving significant results of saving about 700000 kWh of electricity annually, becoming an important milestone for domestic air compressors in the high-end energy-saving field.
In depth analysis of the case: How was 700000 kWh of electricity saved?
The key to the success of this project lies in the systematic design of energy-saving solutions, rather than just replacing a single device. The solutions provided by Sa Zhen mainly include the following aspects: Core equipment upgrade: adopting its flagship product - permanent magnet variable frequency two-stage compression screw air compressor. Compared to traditional single-stage compression, this model has increased energy efficiency by more than 10% and maintains high efficiency even under low load operation.
Intelligent Joint Control System: Multiple air compressor intelligent joint control systems have been deployed to automatically optimize the operation combination based on the tidal gas consumption changes in the factory's production rhythm, avoiding the phenomenon of "big horses pulling small cars".
Pipeline optimization and leakage control: The compressed air pipeline network of the entire plant was surveyed and optimized, reducing pressure loss and repairing multiple leakage points. According to statistics, untreated pipeline leaks can cause 10% to 30% of energy waste.
Waste heat recovery and utilization: An air compressor waste heat recovery system has been installed to convert the large amount of heat generated during the compression process into hot water, which is used for employees' daily life or production processes, achieving the cascading utilization of energy.
This successful case not only demonstrates the breakthrough of domestic air compressors in core technology, but also reflects their ability to provide customized and systematic solutions. As emphasized by the news on SaZhen's official website, cultivating the local market and responding quickly to customer needs are one of the core competitiveness of domestic brands.
