Certification for Zone 2/22 is planned by the end of 2026, and for the more demanding Zone 1/21 by September 2027. CE, IP68/IP69 ingress protection and IK10 impact resistance are already verified today. The construction is designed from the ground up to IEC/EN 60079-1 for flameproof enclosure "d".

ExBox is developed for ATEX Zone 1/21 and Zone 2/22 — environments with a continuous or occasional explosive atmosphere of gases and dust. Zone 1/21 corresponds to equipment category 2G/2D, Zone 2/22 to category 3G/3D. A single certified enclosure therefore covers most industrial sites with an explosion risk.

A zone describes the environment — how often an explosive atmosphere is present (0/1/2 for gas, 20/21/22 for dust). The equipment marking, for example II 2G Ex db IIC T6 Gb, describes the equipment's capabilities: group, category, protection type, gas group, temperature class and Equipment Protection Level (EPL). Category 2 equipment can be used in Zone 1, category 3 in Zone 2.

Yes. The target marking IIB+H₂ means ExBox is designed also for environments containing hydrogen — one of the most demanding gases for explosion protection. This makes it a suitable solution for hydrogen technologies, energy and new fuels, where standard housings fall short.

ExBox is developed for gas group IIB including hydrogen (IIB+H₂) and for both conductive and non-conductive dusts of group III. A solution designed for IIB+H₂ also covers less demanding IIA and IIB environments. For purely hydrogen atmospheres or acetylene (group IIC), ATHEX Technology designs a custom configuration to the specific requirement.

The key parameters are IP rating, IK impact resistance, temperature range and ATEX compliance. ExBox combines IP69 ingress protection per EN 60529, IK10 impact resistance and a −40 to +70 °C range in a single modular construction designed to IEC/EN 60079-1 — so one solution covers requirements that would otherwise need several separate housings. For electronics rated above +70 °C, a higher-temperature configuration can be designed; the resulting resistance depends on all installed components and a final technical assessment.
