ATHENS, Ga. — Carrier Transicold has introduced its ultra-high efficiency X4 Series for North America, which the company says delivers the “highest refrigeration capacities currently offered in a trailer refrigeration platform” while also complying with the US Environmental Protection Agency’s Tier 4 emissions requirements.
“Along with emissions compliance, the X4 Series offers the highest refrigeration capacities ever delivered by Carrier Transicold trailer units, combined with lower fuel consumption, lower maintenance costs, lighter weight and quieter operation than our prior platform,” said David Appel, president of Carrier Transicold.
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. Respectively, the new units provide 68,000 and 66,000 BTUs of cooling at a setpoint of 35 degrees Fahrenheit (100 F ambient).
“Our new X4 Series uses significantly less engine power, fuel and refrigerant while still achieving higher refrigeration capacities and faster pulldown than our previous models,” said Tom Ondo, general manager, Truck/Trailer Americas, Carrier Transicold. “The new units are so efficient that they achieve 35-50% more BTUs of cooling per gallon of fuel, at AHRI rating conditions, than our current designs, making them a smart decision for fleets looking to optimize the efficiency of their refrigerated assets.”
The unit comes equipped a 2.2-litre engine with sensors and an electronic control module that communicates with Carrier’s APX control system for optimized performance.
“Individual components, such as the engine, work less and consume less to produce greater results in a straight-forward design that will be familiar to owners of prior Carrier equipment,” said David Kiefer, director of marketing and product management for Carrier Transicold.
Compared to the Carrier Transicold X2 series models they succeed – the 2100 and 2500 respectively – officials say the new X4 units:
• Weigh 30 lbs less, which, at 230 lbs, makes them about 13% lighter than competitive models designed for 2013 EPA Tier 4 compliance;
• Provide 3-10% higher cooling capacity (depending on model);
• Achieve up to 20% faster pulldown;
• Consume 5-22% less fuel over a full range of operating conditions; and up to 35% less fuel during pulldown;
• Require 24% less refrigerant; and
• Operate at up to 18% slower speeds and reduce engine runtime by up to 15%.
“Ultra-high efficiencies reduce engine fuel consumption, and the greater cooling capacities help the units achieve setpoint faster and shut off sooner in start/stop mode,” Kiefer said. “This saves even more fuel, reducing engine run hours as well as runtime-based maintenance expense.”
Carrier Transicold officials say efficiency benefits actually improve as the units work harder.
“Proportionately, the greatest fuel savings come when the units are operating under the most demanding circumstances,” Kiefer said. “For example, when hauling frozen loads in higher-ambient temperatures, fuel savings of up to 22%, compared to earlier Carrier Transicold models, are possible.”
Other 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 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.
