V-Force fan makes Carrier X2 even quieter
Dec 29, 2008 2:14 PM
Carrier Transicold’s X2 series trailer refrigeration units are now among the quietest on the market, thanks to the coupling of the new V-Force fan with the new Stealth 2 option.
Seven decibels quieter than the traditional condenser fan it replaces, the V-Force fan is now a standard feature of all X2 series units. The new fan is engineered with vortex-suppression tips that virtually eliminate spinning pockets of recirculating air that result in inefficiency and noise. In addition, the new fan minimizes pulsations through fan drive-system components.
For system cooling, particularly in high-ambient operations, the V-Force fan delivers 8 percent more airflow to the radiator and condenser than a conventional condenser fan. A cooler condenser also helps keep down compressor head pressures, reducing the power needed to operate the compressor. With half the weight of the old-style fan, the V-Force fan puts less stress on the fan shaft, bearings, seals, and other drive components.
For particularly noise sensitive applications such as urban deliveries, the Stealth 2 noise abatement option offers additional sound reduction. The Stealth 2 option takes technology from Carrier’s original Stealth package and adds a tuned intake system to the diesel engine, further enhancing noise suppression and sound quality.
The tuned intake system uses a high-capacity noise-suppressing air cleaner and a Helmholtz resonator, an acoustically engineered chamber that captures and dissipates targeted sound waves before they propagate away from the refrigeration unit. The tuned intake system achieves a 30-decibel sound reduction for certain frequencies.
