The Carrier Transicold Engineless Vector 8100all-electric trailer refrigeration unit consumes less electricity and offer higher capacity than the model it succeeds. The latest Vector models use an efficient and fully-sealed electric scroll compressor that has 70 percent fewer moving parts and is 200 lbs lighter than the reciprocating compressor it replaces. This contributes to a 13 percent weight reduction for the Vector 8100 unit. The Vector 8100 also adds the APX control system, featuring a large illuminated dashboard display that provides on-screen temperature graphing, and a USB dock to facilitate data downloads and software uploads.
