The Idle Free electric APU is The Complete Electric APU Solution™ for drivers pulling refrigerated or reefer trailers. This patented, one-of-a-kind idle elimination solution uses the energy produced by a reefer unit to meet all the HVAC needs of drivers—without idling the truck and the cost that goes with it.
Reefer units supply the energy needed to keep temperature-controlled cargo in a reefer trailer at just the right temperature. Because temperature control is a safety issue, reefer units are exempt from emissions regulations, while the diesel that fuels them is exempt from highway fuel taxes.
Like other drivers, drivers pulling a reefer resort to discretionary idling to generate the energy required to meet their HVAC and hotel needs. But because the reefer unit is also running, drivers who idle and run a reefer unit are really running two diesel engines at the same time.
The Idle Free electric APU eliminates this inefficiency with the Reefer Link™ technology. This patented technology allows drivers pulling a reefer to use energy produced by the reefer unit to heat or cool the cab or bunk, warm the engine or fuel tanks, and run a TV or computer with 120 volt AC electricity.
The Idle Free electric APU offers drivers and fleet operators many benefits compared to both discretionary idling and other idle-elimination options, including diesel APUs and other electric APUs.
The Idle Free electric APU works with any make or model of truck pulling a refrigerated trailer. It is also an EPA SmartWay-verified technology, which means it is one of the cleanest and most fuel-efficient available on the market.

The Idle Free electric APU for drivers pulling a reefer trailer is a reefer-based system that uses patented Reefer Link™ technology to make energy from the reefer unit available to the driver when the truck engine is off. Drivers can use this energy to heat or cool the bunk, warm the engine or fuel tanks, and meet their hotel needs with 120 volt AC electricity.
The reefer-based system can be installed on its own or in combination with Idle Free's battery-based system. This is a useful option for trucks that sometimes back haul dry cargo in a refrigerated trailer (i.e., that pull a refrigerated trailer without the reefer unit running).
The reefer-based system includes a standard shore power outlet. This means drivers have at least two alternatives to discretionary idling when truck stop electrification (TSE) services are available.
In addition, the reefer-based system comes in three configurations: combined heat and A/C for year-round idle elimination in all climates; heat-only; and A/C-only. Drivers or fleet operators who choose to invest initially in a heat-only or A/C-only configuration can easily expand their system in the future as budgetary and/or driving conditions change.
