It is not just dust and liquids that industrial computer enclosures protect from. Many enclosures are designed and built to protect from theft and vandalism, perfect for any IT left in public or vulnerable areas such as digital signage or information points. These enclosures should be solidly built and engineered out of the best materials to ensure durability. Why not ask a prospective manufacturer of the types of locations their enclosures are situated.
