Using patented Deltek™ hybrid diesel-electric technology, the Vector 1800MT is Carrier's premier multi-temperature unit, offering unprecedented system reliability, performance and an estimated 30 percent reduction in maintenance cost. The technology eliminates most mechanical components common to conventional trailer refrigeration units and uses an ultra-high-performance generator driven by the diesel motor to power the electrical system. The Vector 1800MT unit's all-electric performance lends itself well to electric standby capability, which allows a parked unit to be plugged into an AC power source, eliminating the need to run the diesel motor.
