Vindur DryCell Mini environments
for battery cell production
Innovative air management increases efficiency, reduces costs and ensures quality.
Innovative air management: the future of battery cell production
Battery cell production requires clean and extremely dry air in order to process moisture-sensitive materials such as nickel and lithium into powerful, long-lasting battery cells. The dry ambient air has so far been provided in large clean and dry rooms with correspondingly large air volumes. This highly energy-intensive process requires up to 50% of the total energy demand for battery cell production.
As part of the QueEn project, Weiss Klimatechnik is taking a completely new approach to making battery cell production more efficient, reducing costs, and ensuring product quality: innovative air management in mini-environments.
Dry air with extremely low dew points
The required dry air for battery cell production has extremely low dew points, currently at -40 °C. New materials for cathodes and electrolytes are even more moisture-sensitive and require dew points as low as -60 °C or lower. This further increases the already high energy demand for air drying.
Protecting Personnel, Preventing Contamination
The dry air in clean and dry rooms poses a significant physical strain on operating personnel. Operators are also one of the biggest sources of contamination. Depending on their level of activity, they introduce particles and a moisture load of 90 to 120 g/h into the process.
Securely Controlling Processes
The high-precision monitoring of temperature, humidity, particle size, and quantity is essential to ensuring the optimal functionality of battery cells. Increasing demands on product quality and lifespan also raise the requirements for air regulation and process security.
Ensuring Long-Term Economic Viability
Battery cell manufacturers must take action: The current energy-intensive production process is not economically viable and presents enormous challenges for industrial locations in Germany and Europe. Significantly reducing the energy costs of air drying provides an excellent opportunity to make a lasting improvement in economic efficiency.

Vindur DryCell Mini-Environments replace large dry rooms
Process-oriented mini-environments featuring innovative air management represent a significant advancement in battery cell production. These mini-environments serve as encapsulated production areas, creating compact, enclosed, and controlled spaces for critical processes. They allow for the precise regulation of air, ensuring it meets the necessary levels of dryness and cleanliness. As a result, only moderate climate conditions are needed in the surrounding production hall to ensure safe manufacturing processes.
