Vector reefer units qualify as quietest

There are plenty of sound reasons for considering the hybrid Vector trailer refrigeration units from Carrier Transicold—and now sound itself is another.

Designed for efficiency and low maintenance, Vector units are also North America’s quietest diesel-powered trailer refrigeration units, based on recent company testing.

The Vector 6500 single-temperature unit was tested by Carrier Transicold in accordance with ARI Standard 1120, paired against a competitive unit of comparable capacity equipped with a factory-installed sound-reduction package. When running in high-speed cooling mode, the Vector unit’s sound output measured six decibels quieter than the competitor.

“Putting this into perspective, it would take four Vector units running in high-speed cooling mode to produce the sound volume of a single conventional competitive unit equipped with a noise abatement package,” said Dave Kiefer, Carrier Transicold’s director of marketing and product management.

Contributing to the Vector unit’s low sound output is its all-electric refrigeration system. Vector units also take advantage of noise-reducing V-Force condenser fans with vortex-suppression technology. With doors designed for acoustic abatement, both the Vector 6500 and its multi-temperature sibling, the Vector 6600MT, include a bottom panel that helps further contain engine sound.

“When parked during loading and unloading, Vector units can be plugged into an outlet and powered electrically, enabling them to deliver full-capacity cooling without using the diesel engine. This ‘standby operation’ drops the sound output by another three decibels in cooling mode. In heating mode, when the compressor operation is not required, the unit is virtually silent,” said Kiefer.

When in standby operation, the Vector units eliminate engine emissions from the refrigeration unit, conserving fuel and reducing operating costs by 40% to 70%.
