Atlas Copco’s compressed air solutions help Kao Group realize safe, energy-efficient production
Wilrijk, Belgium, June 2014. As Japan’s largest producer of chemicals for consumer use, Kao Group has been committed to environmental protection and implements this throughout its development and production processes. Atlas Copco equipment provides 100% pure, clean air that complies with ISO 8573-1 Class 0 certification and boosts energy efficiency at Kao.
Heat recovery units save 52 tons of diesel oil per year
However, Shanghai Kao’s requirements were not just limited to production demands. The company also closely monitors the energy consumption of its air compressors. When Shanghai Kao discovered that energy consumption accounts for over 75% of the life cycle costs of the compressors, they began to consider recovering this energy to heat water used in their production processes.
As much as 94% of the electrical energy used by an air compressor is converted into heat and loss through radiation in the compression process. The remaining 6% is converted into compressed air heat losses. Therefore, a properly designed heat recovery unit can recover up to 94% of this available thermal energy to heat air or water (up to 90°C or 140°F). Preheated water can be used in the application process to reduce the use of traditional energy sources.
Kao uses pure water at a temperature of 80℃ in the filling process. They previously used a diesel boiler to heat the water. Since the installation of energy recovery units in the two ZR 110 compressors, they are able to preheat the process water to 40℃ using this system. As a result, Kao estimates it saves 52 tons of diesel oil per year.
Central controllers ensure optimal compressor performance
“After 10 years of use, our technicians have confirmed the quality of Atlas Copco. The service team of Atlas Copco also responds and helps quickly.” said the chief facility manager at Shanghai Kao
The service team also provides optimized service products such as an annual energy audit, which can help Kao save up to 30% on energy and ensure that all equipment operates at maximum efficiency and minimal cost.
“A growing number of customers have begun to pay attention to lifecycle costs, and they all want to realize the benefits of energy savings and emission reduction at their companies,” Wang Tingzhong, Sales Engineer in the Atlas Copco Service Department, said. “Energy savings and emission reduction are priorities for Atlas Copco, and our company has been devoted to meeting the demands of our customers with sustainable solutions."
