Channel Tunnel Marks Successful Season of Cool Runnings with Trane

Cooling the world’s largest undersea tunnel, the Channel Tunnel, or “Chunnel,” is serious business. First, there’s the structure’s awesome size, stretching a whopping 31.5 miles (50.45 km) from southern England to northern France. But with Trane’s cooling system, powered by Solstice® zd, part of the Honeywell family of Solstice-branded products, the tunnel has completed its first season of cool runnings.
