Traditional electronic explosion protection - provided to electrical equipment through a safety barrier, limiting current and voltage so as not to achieve the small ignition energy and ignition temperature of the explosive mixture.

Increased safety explosion protection requires mechanical support in the form of a housing and mechanical protection for fixtures, screens and electrical components. Additional mechanical protection measures can prevent sparks and impermissible temperatures that may act as ignition sources.

The unit is protected by being installed in a flameproof enclosure to ensure that potential sparks do not escape into potentially explosive atmospheres around - components that can trigger ignition are built into the enclosure that can withstand explosion pressure. The opening of the explosion proof enclosure is configured to prevent explosion from escaping from the enclosure.

The device is housed in a housing that is held under slight overpressure with androgen or non-explosive gases to prevent flammable gases from penetrating. The housing of the device is filled with an inert gas and the explosive gas mixture must not come into contact with a potential source of ignition inside the enclosure.
