As pressure to cut fuel use and emissions grows in long-haul transport, high-capacity electric APUs are becoming vital for heavy‑duty climate control. The largest cooling‑capacity e‑APUs offer powerful, quiet, and emission‑free cabin cooling during rest periods—replacing diesel APUs while improving compliance and driver comfort.

Designed for Demanding Conditions

Heavy‑duty trucks need reliable cooling in extreme heat. These e‑APUs combine high‑output electric compressors with smart energy management to deliver strong, continuous cooling without idling—ideal for large sleeper cabs and hot environments.
