Customized solutions through various equipment

Air conditioning

Optional HVAC equipment for electrically classified interiors.


Optional HVAC equipment for electrically classified interiors.

Technical ventilation

For effective cross ventilation of the hazmat storage.

The control technology is optimally matched to DENIOS Li-Ion storage buildings. It triggers an optical and acoustic alarm in case of a deviation in measured data. In addition, automatic locking or extinguishing systems are activated, for example. All information is on the operating and display elements presented.

Comfort control

Modern touch panels / displays for indoor or outdoor use with high ease of use.

Dry Chem systems

Dry Chem systems provide extra safety in containers used to store Li-Ion batteries and non-flammable substances. DENIOS offers a wet or dry system.

Fire detectors

DENIOS fire detectors are equipped with approved multi-sensors, that detect smoke and fire quickly and reliably.

If explosion protection is needed according to your assessment, we offer you built-in components that can represent a source of sparks in an appropriate Ex version. Earthing devices (e.g. earthing rail) are optionally available for equipotential bonding.


For earthing connection inside the store. Provides the necessary equipotential bonding with an external pin as a connection.


Grounding bracket for equipotential bonding.

Gas warning equipment

Explosion-proof detector transmits LEL values. Used for preventive fire and explosion protection.
