Mack Trucks has introduced a factory-installed electric auxiliary power unit (eAPU) for the Mack Anthem with 70-inch sleeper cab. The Idle Free Series 5000 eAPU features a 10,000 BTU compressor and three-speed evaporator fan to direct airflow to the sleeper without duct work.

It can be retrofit with an automatic start-stop kit, which allows the truck to automatically idle to recharge the batteries then turns the engine off when they are fully charged.

The new eAPU will be available for order in the second quarter of 2022, the company announced.
