Features and Benefits:

  • The X4™ 7700R. A premium performance unit featuring a new smart engine that raises the bar for refrigeration performance, efficiency and sustainability.
  • Ultra-high capacity. Delivers our highest capacity along with fast pulldown, precise temperature control and peace of mind for the most demanding applications.
  • Ultra-high efficiency. Demonstrated 20% better fuel economy than its standard counterpart, thanks to the X4 7700 unit’s advanced smart engine. Common-rail fuel injection optimizes fuel delivery by 5% to 10%, and the engine’s new third “eco” speed adds significantly more fuel savings by reducing engine RPMs during intervals when conditions permit, improving operating efficiency over normal low-speed operation.
  • Enhanced compliance. Reduced emissions that surpass EPA Tier 4, and lifetime compliant with California Air Resources Board (CARB) requirements without the need for future exhaust systems. Sustainability enhanced with R-452A, a refrigerant with lower global warming potential.
  • Nationwide support network of strategically located dealers with the experience and expertise to provide safe and reliable service.
