  • The Vector 8811MT is designed for trailers divided lengthwise with a center dividing wall, the unit creates two refrigerated compartments without requiring a remote evaporator.
  • Optimum flexibility. Unlike competitive systems, it provides 15 inches of center wall placement flexibility for more efficient pallet accommodation and up to 17% more cargo.
  • E-Drive™ technology. Innovative hybrid design uses a new smart engine to drive the generator powering its all-electric refrigeration system, resulting in better fuel economy and performance.
  • Enhanced compliance. Surpasses EPA Tier 4, and lifetime compliant with California Air Resources Board (CARB) emissions requirements without the need for future exhaust systems.
  • Streamlined design. Eliminates check and solenoid valves resulting in fewer braze joints than competitive models. Other system advantages include independent air control, damperless defrost, and consistent all-electric heating.
  • High efficiency. Delivers high airflow, fast pulldown, and low fuel consumption.
