The world of flexographic printing is particularly sensitive to air quality. The fumes from inks and solvents, thermal load, and humidity peaks not only affect the comfort of workers but also the operational reliability of the equipment and the quality of production. Therefore, at the Poli-Union Zrt. printing house in Szeged, two, Blauberg heat recovery air handlers<\/strong> have been implemented in a modern ventilation and air conditioning system: BlauAIR BL15<\/strong> (\u224810,000 m\u00b3\/h) and BlauAIR BL45<\/strong> (\u224848,000 m\u00b3\/h). The larger capacity BL45 maintains stable air exchange and a uniform flow pattern even during peak times when multiple printing machines are running simultaneously, while the BL15 is optimized for serving smaller zones, preparation areas, and accompanying functions. The system connected to cooling thus creates a comfortable<\/strong> modern technologies operationally reliable<\/strong> environment.<\/p>\n\n\n\n

\n Flexographic printing and air quality\n <\/h3>\n\n

\n The world of flexographic printing is particularly sensitive to air quality. The fumes from inks and solvents, thermal load, and humidity peaks not only directly affect the comfort of workers but also the operational reliability of the machines and the quality of printing.\n <\/p>\n\n

\n Flexography is a high-speed printing process that works with flexible printing plates, used in the production of packaging materials, films, papers, and labels. The drying of the ink, its viscosity, and color retention strongly depend on temperature and the composition of the air.\n <\/p>\n <\/div>\n\n <\/div>\n<\/div>\n\n\n\n

Why is printing air technology critical?<\/strong><\/h5>\n\n\n\n

In a printing environment, three factors dominate the design of air technology: heat<\/strong>, a steam\/odor<\/strong> and the solid or liquid aerosol<\/strong> (oil and ink mist) presence. Together, these factors influence not only employee comfort but also the reliability of equipment, reproducible color retention, and the rate of defects. If thermal load is not under control, viscosity and drying profiles fluctuate; if odors and vapors \u201eleak\u201d from the technological zone, the olfactory footprint appearing in the guest area or warehouse poses a reputational risk. heat recovery (HRV)<\/strong> and in today's energy costs, it is not a luxury: it provides a balanced climate and measurable operational savings.<\/p>\n\n\n\n

The key in this project was that the large-volume printing hall receives<\/strong> continuous, even air exchange, along with local exhausts and inflows, all of this draft-free<\/strong> modern technologies at low noise levels.<\/strong>. The Blauberg \u201equiet-tuned\u201d aerodynamics (optimized impeller, laminated air duct, modern heat exchanger geometry) played a significant role in this: with the same air volume, lower pressure drops can be achieved, resulting in lower RPM and less noise entering the space.<\/p>\n\n\n\n
