In Zhang Jian Industrial Park, located in Rudong's Dayu town, Jiangsu Yuntian Energy Storage Technology Co Ltd has developed an advanced energy storage and heating device. This innovative system converts electricity into thermal energy during slack hours at night, which can be released as steam, hot air, hot water, or thermal oil when needed.

Li Jie, the company's boss, highlighted the device's versatile capabilities. "The equipment can provide continuous heating, scheduled heating, charging while in use, or charging before use," he explained. This flexibility makes it suitable for a variety of applications.

"The system can keep energy losses below 5 percent, and it features automatic alarm, shutdown, and startup capabilities as well as remote data transmission and monitoring."

Li also emphasized the environmental benefits of the device. "Our equipment operates purely on electricity, is unaffected by climate conditions, and produces no pollutants. It can help industrial enterprises reduce their carbon footprint."

Yuntian has established energy management contracts with several enterprises, with Yuntian providing the equipment and the cost savings on electricity shared between the client and Yuntian.

Yuntian has completed the construction of an 18,000-square-meter production base for its energy storage equipment. This facility can produce storage units ranging from tens of kilowatts to several megawatts, meeting the heating needs of various industrial enterprises.
