DEFU High-Efficiency 12V 24V RV Tractor Rooftop Air Conditioner SR6

Experience uninterrupted comfort during rest stops with the DEFU SR6 Series–a purpose-built battery-powered parking air conditioner designed for trucks, sleeper cabs, RVs, motorhomes, and vans. This innovative system eliminates the need for fuel-wasting engine idling by operating directly from your vehicle’s 12V or 24V DC battery system, delivering powerful cooling while parked. Engineered as a rooftop or backpack-style split unit, it efficiently transforms your cabin into a cool oasis during breaks or overnight stays.

The SR6 excels with robust cooling performance tailored to your voltage . The 12V model delivers 7,500–9,000 BTU​of cooling capacity, while the 24V model provides 9,000–10,500 BTU, ensuring rapid temperature control in confined spaces. Its optimized design features a compact outdoor unit housing a reliable 2,400 RPM compressor and a high-efficiency aluminum condenser. Inside the cabin, the evaporator unit offers a choice of aluminum or copper construction​for enhanced thermal performance and durability, paired with automatic swing air outlets that distribute cold air evenly at a flow rate of 200–400 m³/h.

Engineered for quiet operation (50–60 dB)​and energy efficiency, the SR6 consumes 200–800W of power. It uses eco-friendly R134a refrigerant, aligning with global environmental standards. The system complies with key international certifications including CE, EMC, and MSDS, ensuring safety and reliability.The SR6 is built for durability and straightforward installation across diverse commercial and recreational vehicles.

Ideal for long-haul drivers and travelers, this parking air conditioner significantly reduces fuel costs, engine wear, and emissions​while providing critical comfort during mandatory rest periods. Upgrade your rest stop experience with the SR6 Series – where advanced DC cooling technology meets uncompromising performance on the road.
