If you love van life, you know that staying cool on the road—or while parked up in the summer sun—can be a real challenge. Traditional air conditioning systems often rely on 230V mains power or noisy generators, which doesn’t fit the off-grid lifestyle many campervan owners crave.
That’s where the Indel B Plein Air 12V Air Conditioner comes in. Designed specifically for campervans, motorhomes, and off-grid builds, this powerful, efficient roof-mounted system keeps you comfortable wherever you travel—no mains hookup required.
🚐 What Makes the Indel B Plein Air 12V Different?
Unlike standard RV or caravan air conditioners, the Plein Air is a true 12-volt unit. It runs directly from your vehicle’s leisure battery, delivering effective cooling without the need for an inverter or generator.
Here’s what makes it stand out:
- ⚡ 12V DC Power Supply – Runs directly off your leisure battery for full off-grid freedom.
- ❄️ 1,200W Cooling Capacity (≈ 4,100 BTU) – Ideal for vans up to around 6 m in length.
- 🌀 Soft-Start Function – Prevents high startup current draw; perfect for battery-powered systems.
- 🌬️ Three Blower Speeds + Auto Mode – Customise your comfort level.
- 💡 Smart Diffuser Options – Choose between the Basic, RingLight or LightBox versions, offering LED lighting and Bluetooth/Wi-Fi control for a premium feel.
- 🌍 Eco-Friendly Operation – No generator noise, no fuel burn, and minimal energy waste.

- Pre-cool the cabin – Run the unit before sunset and maintain with low fan speeds.
Whether you’re wild camping in the Highlands or touring southern Europe, you can stay cool and quiet—no generator required.
🧰 Installation Tips
- Cut a 400 × 400 mm roof opening in a suitable, flat section.
- Check that your roof structure supports 30 – 70 mm thickness.
- Ensure good insulation throughout your van for optimal performance.
- Choose a diffuser model that matches your van’s design and lighting style.
- Use quality sealant and ensure all roof joins are weatherproof.
