New V-Force Fan Makes Carrier X2 Series Even Quieter

Carrier Transicold is now coupling its new V-Force fan with the new Stealth 2 option on X2 series trailer refrigeration units.


The V-Force fan is seven decibels quieter than the condenser fan it replaces and is now a standard feature of all X2 series units. The fan is engineered with vortex-suppression tips that virtually eliminate spinning pockets of re-circulating air that result in inefficiency and noise. The fan also minimizes pulsations through fan drive-system components that can result in additional noise and component wear.

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 for both better fuel economy and longer compressor life. With half the weight of the old-style fan, it puts less stress on the fan shaft, bearings, seals and other drive components.

The Stealth 2 noise abatement option offers additional sound reduction for customers with noise sensitive applications such as urban deliveries. This 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.

"The tuned intake system targets low-frequency rumbling noises that travel longer distances," explained Dave Kiefer, product manger of Trailer Products. "These are wavelengths that cause concerns with neighbors in residential areas near distribution centers or when drivers make urban deliveries."
