Customized Professional Ventilation Solutions

Safeguarding the Production of China Railway Fourth Bureau

China Railway Fourth Engineering Group, a large state-owned construction enterprise and a Fortune Global 500 company, holds four Class-A general contracting qualifications for railway and highway projects. Due to factors such as workshop ceiling height, crane layout, steel structure characteristics, and equipment heat sources, the facility has long faced challenges of high temperatures and stifling humidity. In response, Dawang Ventilation’s permanent-magnet industrial mega-fans swiftly conducted on-site surveys and tailored a customized installation solution for industrial cooling fans designed specifically for this workshop.

1. The factory building has a high ceiling and overhead cranes, making it impossible to install enclosed partitions.

2. Environmental constraints prohibit the arbitrary installation of cooling pipelines and air ducts.

3. The combination of equipment heat sources and steel structures results in high overall cooling energy consumption and low efficiency, compromising operational safety and productivity.
