Carrier Transicold’s Vector trailer refrigeration units now have a dual-voltage option that allows them to operate in standby mode on either 460-volt or 208 to 230-volt electric service.  Vector is an all-electric trailer refrigeration system that incorporates a diesel generator for mobile operation and plug-in standby operation when parked.

Called Flex Power, the new option will allow Vector units to tap into lower voltage outlets in distribution centers and other locations that do not have 460V available.  Cooling capacity is identical with either voltage level, according to the company.

"Vector units with the Flex Power option are ideal when trailers are used to cater large public events, such as golf outings, fairs or sporting events at stadiums and race tracks, where the added noise and diesel exhaust from a traditional refrigeration unit is not desired, and electric power supplies may vary," said Kevin Williams, trailer product manager.

The Flex Power option uses a specially designed step-up transformer with no moving parts.  It is available for Carrier’s hybrid diesel-electric Vector 6500 single-temperature unit, the Vector 6600MT multi-temperature unit and the engineless Vector 5100 designed for stationary use only. It also may be used with Carrier’s original Vector 1800MT multi-temperature unit, and it will be compatible with Carrier’s 2013 Vector units, designed for compliance with the latest EPA Tier 4 requirements.
