en.Wedoany.com Reported - German industrial enclosure manufacturer Rittal recently provided its Hygienic Design enclosures as a support solution for an intelligent camera system in an urban traffic tunnel infrastructure upgrade project. The tunnel infrastructure project involves the major renovation of a key urban traffic artery tunnel, aiming to enhance tunnel safety and traffic monitoring capabilities, including the deployment of real-time monitoring, incident detection, and automatic response systems.
Another type of enclosure was initially specified for this tunnel infrastructure project, but after a detailed technical review, the contractor determined that a solution better suited to the site's environmental conditions and long-term operational requirements was needed. Rittal's HD enclosures demonstrated higher protective performance and environmental adaptability during the evaluation. Originally developed for hygiene-critical industries and designed for environments exposed to moisture, chemical agents, airborne particulates, and regular washdowns, the enclosures' characteristics matched the internal conditions of the tunnel infrastructure.
Key design features of the HD enclosure include a fully welded stainless steel structure for enhanced corrosion resistance, a 30° sloped top cover to prevent water accumulation, and an FDA-compliant blue silicone gasket to ensure sealing integrity. The enclosure achieves an IP66/IP69K protection rating, capable of withstanding high-pressure cleaning and the ingress of fine dust.
Installation work was carried out within the operating environment of this tunnel infrastructure over a period of 12 months, with construction scheduled during weekend closure periods. Rittal supported the delivery through product supply, modular system design, and technical documentation, coordinating with electrical and communication contractors to complete the installation.
This tunnel infrastructure project was implemented by Rittal in collaboration with the contractor, and the final installation results met the technical specifications and environmental requirements of the tunnel environment.
