Control strategy for Koehler Paper not only ensures product quality, but also has a positive impact on sustainability and energy efficiency.
Koehler Paper and airinotec have already worked together successfully in the past. The current project concentrated on the new construction of a winder line and an adjacent hall, with the focus on developing an efficient ventilation solution that meets both the climatic requirements and the customer's sustainability goals.
New ventilation system for the long-established company Koehler Paper in Kehl.
Koehler Paper is a globally active family business in the paper industry that can now look back on 216 years of history. It all began with a paper mill in Loh. Otto Koehler Paper acquired it in 1807 and founded the global company that exists today. Although a lot has changed in the last 216 years, the core areas have basically remained the same: the production of specialty papers and cardboard using state-of-the-art technology. A total of 2,500 employees work at four locations to produce over 500,000 tons of specialty paper and flexible packaging. A hall for the new winder line (RM17) was planned and built for the Kehl site. In the past, airinotec had already designed and installed ventilation systems at Koehler Paper. Due to the excellent cooperation to date, it was decided to start this project together as well. The EnergyOpt Paper control and monitoring system developed by airinotec took a major step towards sustainability, energy efficiency and hygienic production back in 2020.
Initial situation and project scope: Two open hall areas that influenced each other.
The project was initiated to construct a winder line (RM17) and build a new hall adjacent to an existing hall. The challenge was that the two hall areas were open to each other and influenced each other. The aim was to develop a ventilation system that would take into account the existing hall ventilation and at the same time meet the climatic requirements in both parts of the hall. airinotec was commissioned to develop and implement a comprehensive solution.
Various measures were taken as part of the project, including the installation of supply air and recirculation systems on the roof, the installation of hall exhaust air units on the new and existing hall roofs and the conversion of the existing ventilation systems. Particular challenges included coordinating the ventilation between the new and existing halls and ensuring that the entire hall was always ventilated with positive pressure to prevent contamination, especially when processing tissue paper.
Implementation and solutions: Flow monitoring and close cooperation between the trades.
The on-site implementation required innovative solutions, such as flow monitoring at the hall doors to ensure that the ventilation was effective. These measures ensured that the product was demonstrably protected from contamination. Close collaboration with various trades was key to successfully completing the project.
Special requirements and complexity of the project
The particular challenge was that the ventilation of the two hall areas had to be coordinated in order to ensure consistently high product quality. In addition, it had to be ensured that the hall was always ventilated with positive pressure to prevent contamination, especially when processing hygiene paper.
Successful project completion leads to increased energy efficiency.
Overall, the project was a success, leading to improved production conditions and increased energy efficiency. This initiative highlights the importance of energy efficiency and sustainability in the industry and shows how innovative ventilation solutions can help to achieve these goals.
