Recently, with the last humidification unit put into operation in the post-processing section, Huzhou Xin Tianwai Green Packaging Printing Co., Ltd. has fully completed the upgrading of its workshop humidification system. The upgraded system consists of variable-frequency high-pressure micro-mist humidifiers, steel-pipe spray systems, and purified water treatment equipment. Through an intelligent control system, it automatically and precisely regulates equipment start-up and shutdown according to real-time workshop humidity, achieving refined management of humidity in production workshops.
The company’s original workshop humidification equipment had been in service for many years and showed signs of aging, which had a certain impact on the workshop production environment and humidity control. In June 2025, Xin Tianwai officially launched the humidification system upgrade project. To ensure smooth implementation, the company took advantage of the commissioning period of certain production lines and first carried out a pilot upgrade in Workshop No. 3 to verify the stability and reliability of the new humidification technology. During the trial operation phase, the technical team continuously fine-tuned and optimized equipment parameters to ensure that zoned humidity control and overall system performance met the precise humidity requirements for different product categories.
Building on the mature pilot experience, and in response to dry winter air and insufficient workshop humidity for production needs, the humidification system upgrade covering 30,000 square meters in Building No. 1 was gradually and systematically rolled out. In early October, the new system was applied to the “Huishang” New Concept production line; by late October, it had been extended to offset printing and flexographic printing workshops; and by late November, it covered gravure printing, hot stamping, and die-cutting processes. The new humidification system now fully covers all production workshops of Xin Tianwai Company, providing humidity assurance throughout the entire production process.
Following the upgrade, the use of purified water has significantly improved production water quality. Temperature and humidity control in production workshops has remained stable, which is expected to play a positive role in improving product quality, enhancing customer satisfaction, and boosting production efficiency.
