Modern transport infrastructure is becoming increasingly connected. From traffic monitoring systems to incident detection cameras and automated response technologies, tunnels and road networks now rely heavily on sensitive electronics to maintain safety and operational efficiency.
However, these systems operate in some of the most demanding environments. Tunnel infrastructure exposes equipment to moisture, dust, airborne contaminants, vibration, and regular cleaning processes. Without the right protection, sensitive electronics can quickly become vulnerable to corrosion, ingress, and premature failure.
This is why enclosure design plays a critical role in infrastructure reliability.
When new smart camera systems were introduced as part of a major tunnel upgrade on a key urban transport route, the project team required an enclosure solution capable of withstanding harsh environmental conditions while meeting strict protection and compliance standards.
The solution needed to provide:
Rittal’s Hygienic Design (HD) enclosures were ultimately selected to support the project.
While HD enclosures were originally developed for hygiene-critical industries such as food processing and pharmaceuticals, their design features make them well suited to infrastructure environments where durability and ingress protection are essential.
Fully welded stainless steel construction, sloped roof design, and high protection ratings allow HD enclosures to perform reliably in environments where moisture, contaminants, and cleaning processes are common.
To see how Rittal HD enclosures were used to support a major tunnel infrastructure upgrade — and why they were selected over an originally specified solution, read the full case study.
