Enjoy optimal thermal comfort, even at altitude

Don't let the cold hold back your sense of adventure with the Autoterm Air 4D – 12V autonomous heater. Designed for converted vans and campervans, this system delivers constant warmth, even in extreme cold or at high altitude. Running on diesel, it provides remarkable autonomy without relying on an external power supply.

With an adjustable output of 1 to 4 kW, the Air 4D adapts to your needs, whether you are on a winter bivouac or a spring road trip. Its quiet operation and low consumption make it a discreet and economical companion. In addition, its integrated oxygen sensor ensures optimal performance up to 4,200 m. Ideal for adventurers who love exploring the peaks!

Its brushless motor, without brushes, significantly reduces mechanical wear. And this offers more than one advantage:

• Increased longevity
• Quieter operation 
• Better energy efficiency

Tips from the Heode team 

The Autoterm Air 4D – 12V heater is easy to install in various types of vehicles such as buses, trucks, campervans or even boats and yachts. It can be mounted in a storage compartment, under a seat or in a dedicated bay, provided the recommended orientation and ventilation clearances specified in the Autoterm manual are observed.

To connect Ø 90 mm ducts, the following adapters are required:

• Air outlet : Ø 96-90 mm adapter (ref. 2.823)

These accessories ensure a secure connection and optimal airflow. A careful installation guarantees quiet, efficient and long-lasting operation.
