Desiccant dehumidifiers for lithium batteries

Lithium-ion battery manufacturing

Fisair specialises in the production of desiccant dehumidifiers for lithium batteries. The manufacture of this type of battery requires very precise environmental conditions to preserve the qualities of the materials used.

The lithium-ion battery production sector is in constant development and demand has been growing exponentially in recent years. This is due to progress in environmental policies aimed at zero carbon emissions and the commitment to electric means of transport. For this reason, it is important to offer professional and highly efficient solutions to improve processes and productivity. We are talking about desiccant dehumidifiers for lithium batteries capable of achieving dew points from -40 to -60ºC.

At Fisair, we are constantly keeping up with developments in the industry. The production of lithium-ion batteries is constantly evolving, testing new materials and chemical products to reduce costs and improve efficiency.

DFLOW, the desiccant dehumidifier solution for lithium batteries

Fisair has the perfect solution in desiccant dehumidifiers for lithium batteries, the DFLOW range of dehumidifiers.

Lithium compounds are highly hygroscopic and react with moisture in the air, producing hydrogen, lithium hydroxide and heat. This will adversely affect the quality, performance and durability of a lithium battery. It is therefore vitally important that manufacturing is carried out in controlled environments with very low humidity. DFLOW air dehumidifiers are capable of dew point dew points down to -70°C, high operability and minimum energy consumption. This and their ease of cleaning and maintenance, durability and thermal insulation make them the best solution for this type of industrial process.

Fisair has developed an innovative dual heat recovery system for the DFLOW range. This reduces energy use and maximises drying capacity while maintaining the ability to introduce fresh air into the dry rooms for pressurisation. A single rotor system can also be used for these units if required.
