Xiangshui Lianyi Thermal Power Co., Ltd. is a coal-fired power plant located in the Coastal Economic Development Zone of Xiangshui County, Jiangsu Province. The project includes two 130T/h high-temperature, high-pressure boilers, and the compressed air system is designed to support the centralized air supply for two 300,000-ton coated whiteboard paper machines.

Founded in 2001, Ningbo Agsun Products Inc. is headquartered in Ningbo, Zhejiang Province. The company specializes in the production of grills, fireplaces, stove components, plastic parts for electronic ignition guns, and gas appliances.

Based on their actual air demand across the entire factory, Deman replaced the original air compressors with AI Intelligent GGVe series compressors. As a result, the factory achieved an average energy saving of 30 kWh per hour.

Under China’s dual-carbon goals, Xinao, a global leader in wool spinning, stays committed to sustainability and green innovation in wool processing. Deman custom-designed the first ＞40 m³ "Class 1 Energy Efficiency Compressed Air Station" in the fine wool textile industry for Xinao, achieving a power transmission efficiency of 65.1%, exceeding the Class 1 energy efficiency standard by 12.24%.

Compressed air powers modern textile equipment, directly contacting yarn, requiring high quality and large consumption. Optimizing its use is key to energy management.

Deman built the first "Class 1 Energy Efficiency Compressed Air Station" in Jiaxing for Zhejiang Newchuwa Wool Co., Ltd., achieving annual electricity savings of ≈190,000 kWh

Fuzhou Changle Huaya Textile is one of China’s top ten polyester yarn brands. It covers over 300 acres, with more than 1,000 employees, and an annual output value exceeding 5 billion yuan. Deman upgraded the air compressor systems in their No.1 and No.3 spinning workshops. It’s been running stably for over a year since the upgrade with an annual electricity savings ≈ 350,000 kWh

As a photo frame manufacturer, the company strictly controls production because every step affects product look and durability. However, the original air compressors and dryers had high oil and impurities. During chamfer cleaning with air blowing, stubborn oil stains remained, causing frequent quality problems. Products didn’t meet customer standards, leading to many reworks. They heard that Deman machines rank high in quality and offer one-stop systematic solutions. Recommended by friends, they contacted us to consult about upgrading their air compressor station.

This company has been a long-time customer of our distributor—we’ve known each other for over a decade, and there is a strong foundation of mutual trust and familiarity. With the active efforts of our Quzhou distributor, we jointly built the brand new first "Class 1 Energy Efficiency Compressed Air Station" in Quzhou, which is of great significance.

Jieli, a cosmetic packaging company, mainly uses compressed air for UV printing and injection molding. Committed to green development and energy saving, Jieli started working with Deman in 2003 and has trusted Deman’s energy-efficient air compressors ever since. As the factory expanded, Jieli requested Deman to build a new air compressor station to meet increasing air demand.

The customer is a high-tech enterprise specializing in the development, production, and sales of kitchen appliances. Since the first collaboration with Deman in 2017, recognizing Deman’s energy-saving achievements, they have engaged in over ten energy-saving projects.

This well-known home appliance manufacturer based in Cixi reached out to us after hearing about Deman’s strong reputation. We provided a customized air compressor room upgrade using our GGVe series air compressor and 5DV PM VSD refrigerated air dryer. As a result, the factory achieved an annual energy savings of 89,000 kWh.
