Advanced Li-ion Technology

The ComfortPro® Electric Auxiliary Power Unit (APU) with li-ion batteries (250ION) significantly outperforms conventional electric APU runtime and battery life, providing quiet, emissions-free performance with minimal maintenance.

Less, Yet More

Using proprietary power-management technology, two li-ion batteries do more than the work of four AGM batteries, achieving 17 hours of continuous air conditioning under certain real-world conditions, the longest of any electric APU. That’s double the runtime of some competitive models and 50% more runtime than our AGM-battery model, while trimming APU weight by 26%.

Purpose-built Batteries

Advanced li-ion batteries are engineered specifically for APU applications. An extremely power-dense and durable solution, they charge faster and experience less power degradation over time compared to conventional batteries. Warrantied for worry-free performance for five years, outlasting some fleet trade cycles.

Fuel Savings

Fuel savings and compliance with anti-idling regulations are immediate as soon as the truck engine is shut off and the ComfortPro Electric APU is turned on.

Low Maintenance System

With few moving parts compared to diesel APUs, ComfortPro Electric APUs minimize maintenance expenses.

Faster ROI

Compared to a diesel APU, the li-ion ComfortPro Electric APU has a lower total cost of ownership resulting in faster ROI.*
