In Northern Illinois in a small town about 100 miles from downtown Chicago, one of Dover’s steady customers is building Substation Recovery Trailers using the Dover Roller Shutter model 2EB.  Many of these units are being built for National Grid which is one of the largest electrical contractors in the North Central United States.  When floods, tornadoes, lightning, hurricanes, earthquakes, fires, explosions, or any other disasters hit, these units are designed to restore a facility to full service as quickly as possible.   The units can perform all functions necessary for the withdrawal of gaseous SF6, direct high-pressure liquefaction, pressure regulated refilling, and filtration.  Inlet and outlet gauges reflect true pressures of the source and destination containers.

Again, Dover has assisted in the safe design of a critical vehicle.  The seven doors allow quick and safe access to each compartment.
