Phillips & Temro Industries has launched its Idle Free Series 4000 eAPU that mounts behind the cab freeing up space on the truck’s rails.

The Series 4000 eAPU is designed for fleets with over-the-road sleepers with limited frame space and over-the-road sleepers pulling a refrigerated trailer. The location of the APU behind the cab also minimizes its exposure to the environment.

The APU captures and stores energy from the truck’s alternator in independent AGM batteries. The energy is converted into power for cooling and electrification.

“Just as we are challenged to develop APUs to keep abreast of the ever-increasing in-cab power loads, we put ourselves to task and continue to push the design envelope for other needs, as well,” said John Sweazey, product engineer, Phillips & Temro Industries. “In addition to designing an APU that delivers maximum performance, we also took into consideration weight, power sources, endurance and location on the truck.”
