Electric auxiliary power units (eAPU®) deliver all the benefits of idle elimination without compromising performance, cost savings, driver comfort and environmental issues.
Idle Free Systems was established in 2003, initially producing electric APUs specifically for trucks pulling refrigerated trailers.
The Reefer Link Technology patent was issued and began integrating product in 2007. This technology allows drivers to use energy from the reefer unit to heat or cool the bunk or cab, warm the engine and meet hotel needs all without idling their engine.
The acquisition of Idle Free Systems expands PTI’s presence in thermal systems, idle elimination and driver comfort. Headquartered in Madison, Wisconsin, Idle Free provides auxiliary power unit (APU) solutions for over-the-road, day cab, and work truck markets.
Advocate of lean manufacturing, all manufacturing was moved to Eden Prairie, Minnesota facility.
Mounted behind the cab, the Series 4000 eAPU was launched for over the road sleepers with limited frame rail space.
