Carrier Transicold

Carrier Transicold has introduced its ultra-high efficiency X4 Series for North America, delivering the highest refrigeration capacities currently offered in a trailer refrigeration platform, as well as compliance with Tier 4 emissions requirements from the U.S. Environmental Protection Agency.
The X4 Series includes the new 7500 and 7300 single-temperature belt-driven models, which both require less power than Carrier Transicold’s prior platform as well as competitive equipment designed for 2013 Tier 4 compliance. Respectively, the new units provide 68,000 and 66,000 Btus of cooling at a setpoint of 35 degrees.
Carrier’s exclusive  ecoForward technologies refine the design of unit components and equip the 2.2 liter engine with sensors and an electronic control module that communicates with Carrier’s APX control system for optimized performance.

Compared to the Carrier Transicold X2 series models they succeed – the 2100 and 2500 respectively – the new X4 units:

  • Weigh 30 pounds less, which, at 230 pounds, makes them about 13% lighter than competitive models designed for 2013 EPA Tier 4 compliance;
  • Provide 3% to 10% higher cooling capacity (depending on model);
  • Achieve up to 20% faster pulldown;
  • Consume 5 %to 22% less fuel over a full range of operating conditions; and up to 35% less fuel during pulldown;
  • Require% less refrigerant;
  • Operate at up to 18% slower speeds and reduce engine runtime by up to 15%, resulting in improvements in durability and longevity as a result of more lightly loaded components.

System improvements include high efficiency components, such as optimized V-Force fans and Novation micro-channel condenser coils. An electronic expansion valve is now standard, replacing mechanical expansion valves found on previous models and competitive units.

Using 18% less engine power than previous Carrier Transicold models, the X4 unit engines are certified for compliance with the 2013 EPA Tier 4 standard for engines less than 25 horsepower. Fleets will have the ability to equip units with an optional engine emissions system, further reducing emissions to provide future compliance in California beyond the initial seven years.
