Case Study – Zhejiang Xinao Textiles Inc. (Wool Textile Industry)

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%.

Zhejiang Xinao Textile Inc., founded in 1995 and located in Tongxiang, Zhejiang Province, specializes in the R&D, production, and sales of fine wool yarns and intermediate wool top products.

Compressed air powers modern textile equipment, coming into direct contact with yarn. This makes it essential to ensure high air quality and meet large consumption demands. As a key element in energy efficiency management, compressed air plays a vital role in our operations. Under the "dual carbon" goals, Xinao, as a global leader in the wool textile industry, has always upheld the concept of sustainable development, actively exploring innovation in wool and green transformation.

With high recognition of Deman’s capabilities, they approached us to upgrade their old air compressor station. So we conducted multiple on-site surveys and in-depth assessments at Xinao, thoroughly analyzing their compressed air usage challenges and identifying key pain points.

Customer Challenges Before the Upgrade:

1. High energy consumption of old units; poor overall efficiency

2. Refrigerated dryer + dessicant dryer

① Insufficient water removal performance, affecting product quality

② The dessicant dryer consumed a large amount of energy

3. The existing drains caused air loss, resulting in energy waste

Based on our findings, we provided a professional and comprehensive solution for high-efficiency air usage across the entire plant.

Deman's Air System Comprises of:

1. Deman Energy-saving Ultra-high Efficiency Air Compressors

① Withstands high pressure and high temp

② Strong operational stability

③ Long service life

2. 5DV Intelligent PM VSD Refrigerated Air Dryer

① Excellent water removal capability with stable PDP

② Maximizes efficiency utilization

3. Deman Aluminum Alloy Super Piping System

① Significantly reduces energy loss and maximizes energy efficiency

② Exceptional safety, reliability, and durability

4. Zero-air-consumption Drainage System

As a result, the "Class 1 Energy Efficiency Compressed Air Station" built by Deman for Xinao delivered remarkable results and made a significant contribution to China’s environmental protection efforts.
