Ex Phones: essential communication tool in EX environments

In industrial plants where there are gases, vapors, mists or dusts capable of causing an explosion, standard electronic devices pose a serious threat. A spark created by a short circuit or even battery charging can initiate a disaster. Therefore, the use of certified communication devices, such as Ex Phones, is a key element of safety and work efficiency. They are designed with the highest safety standards in mind, enabling reliable communication in the most demanding conditions.

Phones for zone 1/21: the highest level of protection

Zones 1 (gases/vapors) and 21 (dusts) are areas where an explosive atmosphere may occasionally occur under normal operating conditions. Devices intended for these environments must meet rigorous requirements, holding certificates for explosion group IIC/IIIC. Phones for zone 1/21 are characterized by a design that minimizes the risk of ignition through an intrinsically safe enclosure, special seals, and surface temperature control. These are often smartphones or mobile phones that retain full functionality while ensuring safety even in critical moments.

Phones for Zone 2/22: protection in conditions of lower risk

Zones 2 (gases/vapors) and 22 (dusts) are areas where an explosive atmosphere occurs rarely and lasts for a short time. Although the risk is lower than in zones 1/21, the use of specialized devices is still necessary. Phones for zone 2/22 (often integrated with a certificate for dust zone 22) are an economical, yet still certified option. They provide the necessary durability, resistance to dust and water ingress (high IP classes), as well as an explosion-proof design that eliminates the risk of sparking under normal operating conditions.

Ex phone accessories: safety and functionality

The full functionality and safety of phones in EX environments also depend on appropriate Ex phone accessories. These include intrinsically safe headsets, noise-canceling microphones that improve communication quality in noisy plants, as well as special chargers and docking stations. The use of uncertified accessories, such as ordinary headsets, may violate the ATEX certificate and create a risk of ignition. Therefore, to maintain the integrity of the entire communication system, all additional elements must be equally carefully selected and certified.
