Electronic Road and Tunnel Management
Roadways and tunnels present challenges to the electronics that light the way and monitor traffic. The safe and smooth operation on both must be guaranteed at all times. To achieve this level of safety, the technology for the entire road and tunnel management systems, as well as individual components, such as the electrical enclosures for lighting and machinery, must be kept at the optimum temperature and free of condensate. That’s where we come in.

Tunnel Construction and Management

Our DTS Cooling Units meet an IP65 rating to handle extreme alternating pressure loads but also extreme temperature differences and constant exposure to dust and moisture.

Electronic Road Management

DTS Cooling Units keep the roadside equipment from overheating, and heaters, thermostats and hygrostats are added to prevent condensation.

TUNNEL  MANAGEMENT

Some of the world’s most known tunnels utilize Pfannenberg’s signaling solutions and cooling units to ensure traveler, worker and equipment safety. A modified version of our DTS Cooling Units provide specialized thermal management of electronics in the St. Gotthard Tunnel. And our flashing sounders are used to warn workers before and during vehicle movements for tunnel or roadways maintenance. With a broad spectrum of frequencies they provide excellent penetration of acoustic barriers such as walls and doors and are reliable in tough outdoor environments.

ELECTRONIC ROAD MANAGEMENT

Virginia has the third-largest state-maintained highway system in the country, and depends heavily on electronic road management to monitor, track, and bill drivers for toll road use. The overhead displays, tracking machines and computers that implement EZ Pass system for example, rely on Pfannenberg DTS Cooling Units to keep the roadside machines cool and operating in any weather. Heaters, thermostats and hygrostats are added to keep the relative humidity above the dew point to prevent condensation on electrical components and the corrosion of unprotected sheet metal.
