BAUER walk-in container - 3 x 3 m for lithium-ion batteries

Technical data

Material: Steel
Outer dimensions (mm): 2 830 x 3 800 x 2 750

Product information „BAUER walk-in container - 3 x 3 m“

The BAUER storage container with one storage level is a high-performance, future-proof solution for the safe, organised and compliant storage of lithium-ion batteries.

Thanks to its robust steel construction, integrated spill containment sump and high level of fire protection, the container is suitable for both indoor and outdoor use and meets stringent requirements for safety, functionality and durability.

The container holds a general building approval issued by the German Institute for Construction Technology (DIBt), Approval No. Z-38.5-103, and therefore complies with current German building regulations relating to fire protection, structural stability and environmental protection. It forms a self-contained, independent fire compartment, helping companies to reliably minimise risks and ensure safe operational processes.

As each fire protection container is an individually configured project solution, specific requirements such as battery type, storage quantity, installation location, fire resistance rating and technical equipment must be taken into account. We therefore provide a structured project questionnaire. Based on the information provided, we can prepare an individual quotation tailored to your requirements.
