The first, and only, very green transport refrigeration unit (TRU) that is powered on-board the truck while going down the road and an electrical outlet when it isn't. No diesel fumes or carbon emissions like all the rest of them hanging on the front of those refrigerated trailers you pass on the highways everyday. The time has come to eliminate those dirty units. The two companies that manufacture them won't. Join ElectraCold and help clean the air. And, make a great deal of money while doing it.
