CEMO fireproof battery storage cabinet 8/20 LockEX 2.0

The problem with limited storage space is often that there is no room for large safety cabinets for storing lithium-ion batteries or that they are too inflexible if the space available in the warehouse changes at short notice. CEMO offers the optimum solution here, which can be expanded at any time and can also be adapted to the needs of your business.

Size, structure and function of the battery storage cabinet

In this version, the CEMO battery storage cabinet is a pure storage system including smoke detector. The external dimensions are 800 x 660 x 2130 mm (W x D x H), the internal dimensions 730 x 530 x 1760 mm, the weight 266 kg. The maximum energy density that should be stored in the cabinet is max. 12 kWh according to the VDMA test. Each of the levels should not be loaded with more than 1.5 kWh.

Without power connection and ventilation

This version of the battery storage cabinets from CEMO does not include a power connection or active ventilation. The battery storage cabinet comes with two shelves as standard, one for each fire compartment. Feet are included in this version.

Tested and approved in accordance with VDMA standard sheet 24994:2024-08

VDMA 24994 is a test standard specifically for fire-resistant storage cabinets designed to safely store lithium-ion batteries. It tests whether the cabinet can withstand a thermal runaway, i.e. dangerous overheating and spontaneous combustion of the battery. It is important that the cabinet does not emit any flames or toxic gases to the outside and that the door does not open under pressure. This standard helps companies to significantly increase safety when storing lithium-ion batteries and is considered an important benchmark that is increasingly recognized by manufacturers and insurers.

Equipped with the CEMO lockEX 2.0 lock

With lockEX 2.0, CEMO presents the latest evolutionary stage in the storage of hazardous materials. Developed to meet the highest security requirements, the system offers effective protection without a time limit - far beyond the standard 90 minutes.

The design is based on an intelligent spring mechanism which, in the event of a damaged Li-battery exploding, gently opens the cabinet doors to dissipate the resulting pressure and then immediately closes them again securely.

The protection granted by the German Patent and Trademark Office is particularly important here. It has long been known among experts that lithium batteries can not only cause flames and explosive burning of individual cells, but also a gas explosion due to leaking cell vapors. This is the worst case scenario in the event of a battery fire, as it can nullify the entire protective effect in case of doubt and can therefore be the most decisive criterion in the risk assessment.

CEMO lockEX combines fire protection and explosion protection in one product and offers a reliable solution for dealing with potentially dangerous battery fires.

The lockEX technology effectively interrupts the progress of a battery fire. An explosion can occur even before a thermal runaway begins. If the enclosure housing gives way or the doors open, the protective effect can be lost immediately and the burning cells and battery packs are propelled unhindered into the environment at the installation site.

CEMO's lockEX mechanism ensures that the explosion pressure that builds up inside the enclosure is effectively managed. This advanced NO-BANG technology ensures that protection is maintained without restriction, even in the worst-case scenario of a battery fire.

Well equipped in the event of an accident

Critically damaged lithium-ion cells in particular can pose a serious risk to people and equipment in the event of a fire ("thermal runaway"). Dust caused by these fires can settle on the circuit boards of production and operating devices and damage them permanently. This storage cabinet has an MPA-tested fire resistance over 60 min from the inside to the outside in accordance with DIN EN 1363-1. A real battery fire test was carried out with an independent university. The supply and exhaust air openings close automatically in the event of a fire. However, the doors should always remain closed during storage.

Robust construction

The storage cabinet is made of robust, fire-resistant components. Special fire protection seals prevent flames from escaping and it has a cold smoke-tight closure system for the openings. The doors are double-leaf and lockable with sturdy locking and suspension. the doors are painted in orange, similar to RAL 2004, and the body in gray, similar to RAL 7035.

Portable use

With the stacking feet, the cabinets can be optimally stored up to a height of 2 units. The stacking feet also allow the cabinets to be driven under. As an option, the cabinet can also be fitted with a fire-resistant and tested cable entry, for example to connect to the in-house fire alarm system.

Guidelines

There are currently no legal regulations for the storage of lithium batteries / lithium-ion batteries. Only VdS Schadenverhütung GmbH issues general safety rules for damage prevention in its publication VdS 3103 : 2019-06 (03). It is advisable to clarify your requirements with your property insurance company in advance.

The manufacturer

CEMO GmbH from Weinstadt has stood for safe storage with imagination and drive for more than 60 years. The company is a pioneer in the field of modern transport and storage container technology and is one of the market leaders in this area.

Future-oriented

Lithium-ion batteries will be indispensable in all industrial applications in the coming years. However, if used improperly, batteries can pose a potential hazard during production, storage and transportation that should not be underestimated. By purchasing this storage cabinet, you protect yourself against major financial losses right from the start.
