EX ST Signaltower

EX ST – LED signal tower for EX zones 1, 2, 21 & 22

The EX ST LED signal tower is the reliable solution for status and condition indication in potentially explosive industrial environments. Designed for use in EX Zones 1, 2, 21, and 22, it offers maximum safety and flexibility for signaling operating states, faults, or fill levels. Thanks to its robust construction and modern LED technology, it provides clear, highly visible signals – even under extreme conditions.

The signal tower can be individually equipped with up to five LED color modules and is optionally available with a flashing light function. Its robust die-cast aluminum housing and impact-resistant borosilicate glass tube make it ideal for demanding applications such as petrochemicals, refineries, shipbuilding, sewage treatment plants, or hazardous area manufacturing facilities. Various voltage options enable flexible use in control and automation systems as well as in larger industrial plants.
