Best climate for strong battery cells

Drying room systems from Weiss Technik

  • Drying room systems from Weiss Technik

Drivers in the race for the best electric drives today are storage batteries with maximum capacity. Weiss Technik equips battery cell manufacturers with dry room systems that ensure the highest quality standards. The supplier, known among other things for its environmental simulation technology, configures customised systems for battery cell production.
 

Humidity in the production facilities reduced to a minimum is the key to long-lasting and powerful lithium-ion batteries. In this task, Weiss Technik benefits from the company's many years of experience in creating ideal climatic conditions even under the most extreme conditions. Dry room systems from Weiss Technik dehumidify the room air in battery cell production to a residual water content of up to 0.001 grams per kilogram of air. This corresponds to a dew point of -70 degrees Celsius.

To keep the production climate constant under all conditions, the battery cell production chambers are hermetically sealed off from the outside climate. Dry room systems from Weiss Technik first cool down the ambient air in the production area, whereby a large part of the moisture condenses. In a second stage, specially coated drying wheels remove the residual moisture until the desired value is reached. To keep the climate in the drying chamber system constant under all conditions, the system generates a slight overpressure. This protects the chamber from the penetration of more humid outside air.

Weiss Technik plans its drying room systems individually according to customer requirements. One of the plant manufacturer's specialities is the integration of climate chambers into existing building structures. Weiss Technik integrates the dehumidification technology and the architecture of the drying room from a single source in the production of battery cells, which are planned from scratch. Weiss Technik is currently the only system manufacturer to offer complete solutions for all ventilation, air purification and dehumidification technologies in relation to special climate requirements. New systems can thus be planned at optimal cost.

After commissioning their plants, battery cell manufacturers benefit from a comprehensive support package. The technical service can be reached by telephone around the clock and is on site within 24 hours on working days. The maintenance contracts with Weiss Technik can be customised for the customer, and spare parts are available overnight from a central warehouse.
