Within industrial environments where explosion hazards are present, ATEX zones are often used. Yet in practice we see that the difference between zone 1 and zone 2 is regularly misinterpreted. This may seem like a detail, but it has direct consequences for the design and implementation of a switchgear cabinet. A wrong assessment can lead […]

In many industrial facilities, overpressure is used in a control cabinet to prevent contamination, moisture and harmful external influences. Consider environments with dust, vapors or temperature fluctuations where electronic components are prone to failure. In theory, the principle is simple: through controlled airflow and slight overpressure, you prevent contaminated air from entering the cabinet. In

In industrial environments where explosion hazards are present, overpressure in switchboards is often discussed. In practice, confusion frequently arises here: when is standard overpressure sufficient, and when is a purge system mandatory? This confusion is not without risk. Misapplication of a protection method can lead to unsafe situations, rejection during inspections or downtime of installations.
