The Carrier Transicold Vector HE 19 is a thin-profile domestic intermodal container refrigeration unit developed for high efficiency, greater refrigeration capacity, and lower environmental impact. The unit uses refrigerant R-452A and is ideal for 53' domestic intermodal containers due to its thin-profile, allowing for more cargo to be carried. It features patented E-Drive technology, developed by Carrier Transicold, where intelligent controls automatically activate individual components running only what it needs, when needed, so components run less and last longer. The Vector HE 19 unit also has integrated electric standby, enabling the unit to be plugged into a power source when parked, eliminating emissions and noise from the refrigeration unit engine, conserving fuel and reducing operating costs.
