Recently, the plant ventilation project of APP IKK Industrial Park, contracted by Hunan Three Craftsmen Technology Co., Ltd., has been fully completed and passed the acceptance inspection in one go. The project covers the installation and commissioning of industrial fans, anti-corrosion air ducts, and a complete set of ventilation pipelines, which is tailored for the high-temperature, high-humidity and highly corrosive working conditions in papermaking buildings. During the project, the Chinese technical team, together with a local construction team of over 100 people, overcame difficulties such as the rainy season's hot and humid weather and strict construction standards, and recently delivered a project that meets all standards. This delivery deepens the cooperation with APP Group and lays a solid foundation for the subsequent implementation of chilled water and supporting ventilation projects.
