Utility Trailer Manufacturing says it has designed a special prep package for the 3000R refrigerated trailer “to match the significant improvements in reliability, performance and
life expected with hybrid [refrigeration] systems.” It provides an engineered interface between the trailer and the refrigeration system.

Utility says it recognized that this interface has an impact on overall performance and reliability, especially in demanding applications like multi-temperature, where heavy
fork-lift traffic, multiple door openings and movable bulkheads make them more prone to damage and wear.

Among the newly engineered features specifically for hybrid multi-temp applications is a flush, heavy-duty, divided aluminum trough that houses refrigeration lines and electrical cables in separate compartments; a full length, grounded, copper channel surrounding the high-voltage cable; and a quarter-inch thick trough cover to better protect the high-voltage cable from damage from fork truck masts and shoring bars.
