AR2 PRO dual motor diesel heater for rooftop tents, campers and vans
The AR2 is the dual motor diesel heater in the Braguscamp PRO range. Instead of a single fan, it has two brushless motors, each with its own variable-frequency control: one meters the combustion air and the other drives the warm air. The result is a cleaner flame, steadier heat and less diesel for every hour of use.
It is designed for people who sleep in a rooftop tent, camper or van and want dry heat without installing anything in the vehicle. Combustion air and the air that reaches your tent travel in separate circuits: only clean, warm air goes inside, and exhaust gases leave through the exhaust pipe outdoors.
Power it from your vehicle's 12 V battery, from a 24 V system or from a portable power station with a 12 V output. Its twin 6 L + 10 L tank gives you several nights of runtime, and you control it from the LCD panel or with the remote.

Why choose the PRO dual motor diesel heater
Heat in 2 minutes
It starts blowing warm air in about 2 minutes and heats spaces from 15 to 35 m².
Dual brushless motor
Precise combustion and a constant 14.2 m/s airflow, with less carbon build-up.
Minimal consumption
Between 0.12 and 0.37 L/h, with a combustion efficiency of at least 82 %.
Twin 6 L + 10 L tank
Up to 16 L of diesel: many warm nights without refuelling.
12 V and 24 V
Car, truck or van battery, or a power station with a 12 V output.
Up to 5,000 m altitude
Starts and runs steadily in high mountains, even in severe cold.

How to connect the dual motor diesel heater to a rooftop tent
The heater always stays outside, on the ground. Only the warm-air duct enters through the side port of your rooftop tent, so there is no combustion or smoke inside. Set-up is tool-free and takes just a couple of minutes.
- Place the heater on the ground, level and stable, under the tent and close to the side port.
- Fit the side exhaust pipe with the muffler and heat sleeve, pointing outwards and away from the tent and the air intake.
- Connect the Ø 76 mm warm-air duct to the Ø 75 mm outlet and secure it with its connector.
- Pass the other end through the tent's side port and close the drawstring or Velcro around the duct.
- Fill the tank with diesel, connect the power, switch on and set the temperature on the panel or remote.

Power: 12 V, 24 V or power station
12 V battery
Connect it to your car or camper battery with the cable supplied. For full nights with the engine off, we recommend an auxiliary LiFePO4 battery.
24 V system
It accepts 12 to 24 V DC, so it also suits trucks, buses, boats and vehicles with 24 V systems.
Power station
Use it with a portable power station with a 12 V DC output for heat away from the vehicle, at camp or in a cabin.
Diesel consumption and runtime
Consumption depends on the temperature you set and how cold it is outside. These are approximate figures:
| Minimum power | Maximum power | |
|---|---|---|
| Diesel per hour | 0.12 L/h | 0.37 L/h |
| Diesel per night (8 h) | ≈ 1 L | ≈ 3 L |
| Runtime with the 6 L tank | ≈ 50 h | ≈ 16 h |
| Runtime with 6 L + 10 L | ≈ 130 h | ≈ 43 h |
Use diesel only. Do not use petrol, kerosene or other fuels. Figures are approximate and vary with ambient and set temperature.

PRO range vs AR1: what changes
If you already know our AR1 portable diesel heater, the AR2 PRO goes a step further in efficiency, tank size and warm-air reach:
| AR1 | AR2 PRO | |
|---|---|---|
| Motor | Standard | Variable-frequency dual brushless motor |
| Diesel consumption | 0.16–0.45 L/h | 0.12–0.37 L/h |
| Tank | 6 L | 6 L + 10 L |
| Recommended area | 20–25 m² | 15–35 m² |
| Adjustable temperature | 8–35 °C | 10–45 °C |
| Warm-air reach | — | Up to 5 m |
| Combustion efficiency | — | ≥ 82 % |
| Power supply | 12 V · 230 V with adapter | 12 V and 24 V DC |
| Control | LCD display, remote and Bluetooth app | LCD panel and remote control |
Need to plug it into 230 V or control it from your phone? Then the AR1 is your heater. If you want maximum savings, a bigger tank and longer warm-air reach, the AR2 PRO is the one.
