Fuzhou Changle Huaya Textile Co., Ltd., located in Changle City, Fujian Province, was established in 1999. It covers over 300 acres, with more than 1,000 employees, and an annual output value exceeding 5 billion yuan.

The company specializes in the manufacturing of knitted and woven textiles, including polyester yarn and polyester-cotton blended yarn. So far, it has become one of China’s top ten polyester yarn brands.

Due to the high air quality requirements of textile products and Huaya’s growing production scale, the original compressed air system had become outdated.

Customer Challenges Before the Upgrade:

1.Slow after-sales service response

2.Aging machine, frequent shutdowns from overheating

3.Air dryer pressure loss, poor water removal performance

4.Old galvanized pipes and rubber hoses corroded fast, lost pressure, and reduced air efficiency

The Deman team promptly visited Huaya’s factory on site and developed a detailed compressed air system upgrade plan for their No.1 and No.3 spinning workshops.

Deman's Air System Comprises of:

1. 2*110kW+2*90kW Deman air compressors (three for regular operation, one as a backup)

①Flexible allocation and staggered air supply

②Stable system operation

③Significantly reducing no-load energy consumption

2. Two Deman 5DV PM VSD refrigerated air dryers

①Match workshop specific needs precisely

③Boosts air efficiency by over 15%

The installation of the Deman compressed air system has provided a solid foundation for Huaya’s high-quality production.

While significantly improving air quality, it has also led to substantial cost savings.
