Today there are millions of vehicles registered in the United States. Comuters spend, on average, 25 minutes getting to work each day. That
number would certainly be higher without the technology infrastructure controlling
vehicle signals, pedestrian signals, traffic controllers and programmable
changeable message signs that are now a part of the country's landscape.
A vital part of these systems are the cabinets which contain the electronic controls
for these devices. Control cabinets contain a variety of sensitive electronics,
including relays, microcomputers, switches and power supplies. As in other applications,
these electronics require cooling for reliable operation. In some situations fans and blowers are sufficient,
but in others active cooling is required to keep these components running smoothly.
Several manufacturers of traffic control equipment have been using Kooltronic's
Guardian and GuardianX Series Air Conditioners to maintain the optimal temperature within
