Product information „CEMO storage cabinet 8/20 LockEX 2.0“

In many cases, limited storage space poses a problem in that there is no room for large safety cabinets for storing lithium-ion batteries, or these cabinets are too inflexible if the space available in the warehouse changes at short notice. CEMO offers the ideal solution here, which can be expanded at any time and adapted to the needs of your business.

Without power connection and ventilation

This version of the CEMO battery storage cabinet does not include a power connection or active ventilation. The battery storage cabinet comes with two shelves as standard, one for each fire compartment. This version includes feet.

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

VDMA 24994 is a testing standard specifically for fire-resistant storage cabinets designed to safely store lithium-ion batteries. The standard tests whether the cabinet can withstand a so-called thermal runaway, i.e. dangerous overheating and self-ignition 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 even under pressure. This standard helps companies to significantly increase safety when storing lithium-ion batteries and is considered an important benchmark that is increasingly recognised by manufacturers and insurers.

Equipped with the CEMO lockEX 2.0 lock

With lockEX 2.0, CEMO presents the latest evolutionary stage in hazardous material storage. Developed for the highest safety requirements, the system offers effective protection without any time limit – far beyond the standard 90 minutes available on the market.

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

The protection afforded by the property right registered with 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 combustion of individual cells, but that a gas explosion due to escaping cell vapours is also to be expected. This represents the worst-case scenario for a battery fire, as it can negate the entire protective effect and thus 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 course of a battery fire. An explosion can occur even before thermal runaway begins. If the cabinet housing gives way or the doors open, the protective effect can be lost immediately and the burning cells and battery packs are thrown unhindered into the surrounding area at the installation site.

CEMO's lockEX mechanism ensures that the explosion pressure that builds up inside the cabinet is effectively managed. This advanced NO-BANG technology guarantees that the protective effect 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 danger to people and operating equipment in the event of a fire ("thermal runaway"). Dust produced by these fires can settle on the circuit boards of production and operating equipment and cause permanent damage. This storage cabinet has MPA-tested fire resistance of over 60 minutes 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 air intake and exhaust openings close automatically in the event of a fire. However, the doors should always remain closed during storage.

Robust construction

The storage cabinet is constructed from 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-winged and lockable with a sturdy lock and suspension.  The doors are painted orange, similar to RAL 2004, and the body is grey, similar to RAL 7035.

Portable

The stacking feet allow the cabinets to be stored optimally up to a height of 2 units. The stacking feet also make them wheelable. Optionally, the cabinet can also be equipped with a fireproof 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 (VdS Risk Prevention Ltd.) provides general safety rules for damage prevention in its publication VdS 3103 : 2019-06 (03). It is advisable to clarify your requirements with your property insurer in advance.

The manufacturer

With imagination and drive, CEMO GmbH from Weinstadt has been synonymous with safe storage 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 become indispensable in all industrial applications in the coming years. However, if used improperly, the batteries can pose a potential hazard that should not be underestimated during manufacture, storage and transport. By purchasing this storage cabinet, you are protecting yourself against major financial losses right from the start.

FAQ

Standard security cabinets are designed for indoor use, so they cannot be used outdoors.
The fire protection panels installed in the cabinets contain gypsum, which contains a lot of water, which expands when frozen. This deforms the panels. It can no longer be guaranteed that such a cabinet is still sealed or can withstand an explosion.

If you already have a suitable room that is structurally fire-resistant, then you do not necessarily need a safety cabinet to contain the fire.

However, please do not forget that the damage caused by a battery fire involves immense and also toxic contamination, the disposal of which can quickly lead to high costs.

In addition, you may not be able to continue working as usual until the damage has been finally repaired - depending on the location of the damage.
