Why choose 12V air conditioning?
Sleep better, tour further and stop relying on electric hook-up.
Hot vans, restless nights and campsite dependency can take the shine off summer touring. Indel B 12V air conditioning is designed for owners who want proper cooling comfort, more flexibility and a smarter off-grid setup.
Built for lithium and solar
If you already have, or are considering, lithium batteries and solar, this is the cooling upgrade that helps turn your leisure vehicle into a serious off-grid touring setup.
Better nights in hot weather
Reduce heat build-up in the sleeping area and make your motorhome or campervan more usable when temperatures rise at home or abroad.
Why this system is different
Proper air conditioning without a generator, inverter or campsite dependency.
The Indel B Plein-Aircon 12V system has been developed for campervans and compact motorhomes that need real cooling without the usual mains-power limitations. That means more freedom, more comfort and better use of your vehicle through the summer season.
- Ideal for campervans and smaller motorhomes up to around 6 metres.
- A strong match for lithium battery and solar-powered vehicles.
- No generator or inverter required for 12V operation.
- Touch display, smart modes and app-control options depending on model.

Frequently asked questions
Straight answers before you request a quote.
Can it run without electric hook-up?
Yes, the core proposition is 12V auxiliary battery operation. The actual runtime depends on your battery capacity, charging system, temperature and how the vehicle is used.
Do I need lithium batteries?
Not always, but lithium often makes the most commercial sense for owners wanting serious off-grid use. We can assess your current setup and advise properly.
Is it suitable while driving?
The Indel B material positions Plein-Aircon 12V as usable in motion. Suitability still needs to be reviewed against your vehicle, installation and power setup.
Can you advise on solar as well?
Yes. The strongest installations are planned as a complete power ecosystem: air conditioning, lithium, solar, DC charging and real-world touring usage.
