Carrier Transicold’s X2 said it 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 re-circulating air that result in inefficiency and noise. In addition, Carrier said the new fan 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 fan delivers 8% more airflow to the radiator and condenser than a conventional condenser fan, according to the maker. 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, the V-Force fan puts less stress on the fan shaft, bearings, seals and other drive components.

For customers with 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 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 – Trailer Products. “These are wavelengths that cause concerns with neighbors in residential areas near distribution centers or when drivers make urban deliveries.”
