The CorunClima Electric Auxiliary Power Unit (APU) represents a transformative leap in cabin climate and power management for long-haul semi-trucks. Designed specifically for the demands of fleet operations, this system eliminates the need for a traditional, diesel-fired APU.

At its core is a high-capacity, automotive-grade lithium-ion battery pack that directly powers the entire system. This direct-drive, battery-electric architecture provides silent, maintenance-free heating and air conditioning for the sleeper cab, ensuring driver comfort without idling the main engine. By removing engine idling, fleets can achieve dramatic reductions in fuel costs, carbon emissions, and engine wear-and-tear.

Key advantages for long-haul fleets include:

Significant Operational Savings: Cuts fuel consumption from overnight idling by up to 90%, offering a rapid return on investment.

Full Compliance & Sustainability: Produces zero onboard emissions, ensuring compliance with strict state and local idling regulations and supporting corporate sustainability goals.

Enhanced Driver Comfort & Retention: Provides quiet, vibration-free heating and cooling throughout rest periods, along with auxiliary power for appliances.

Reduced Maintenance: No diesel APU means no engine oil changes, fuel filter replacements, or exhaust system repairs.

The CorunClima Electric APU is the intelligent, clean, and cost-effective choice for modern fleets looking to optimize their total cost of ownership while prioritizing driver well-being and environmental stewardship.
