Autoterm Air 2D (Planar 2D) diesel-parking-heater
Autoterm Air 2D (Planar 2D) Diesel parking heaters
The parking heaters made by the Russian manufacturer Autoterm, have bekome known under their former name Planar 2D. They are an indispensable part of campers, mobile homes and expedition vehicles. They are designed for continuous use and are particularly valued for their reliability and safety.
With low fuel and power consumption, as well as good controllability in different modes, they are suitable for travel vehicles on land as well as on water.
All Autoterm heaters have an E-mark. The installation of the heaters does not require a TÜV approval or registration and can also be carried out by laypeople while the camper is being converted without loss of guarantee. Of course, our installation partners are also happy to take on this work, if desired.
Suitable for every type of vehicle
The Autoterm Air 2D is available for vehicles with 12 V on-board voltage as well as for vehicles with 24 V, such as truck-based expedition vehicles.
For every travel destination - the altitude kit
A travel vehicle with an Autoterm Air is not only perfectly equipped for very cold weather - great heights are also no problem. In the past, the lower oxygen supply in the combustion air quickly led to soot in the combustion chamber. In the meantime, the heaters have been equipped with an altitude kit that regulates the combustion. Depending on the ambient air pressure, the heater automatically adjusts the amount of fuel injected downwards.
We at tigerexped are proud to have initiated and helped to develop this innovation at the manufacturer, because the wishes of our customers are our command ;)
Is there still a "too high"?
After our own, successful tests at a height of 3440 m on the Pitztal glacier, the altitude kits went into series production. In the meantime, our customers have traveled with it all over the worls. Fabian for example, with his "Tornado on Tour". He tested the heater (which at that time was still called Autoterm Planar 2D) in his VW T3 bus in Chile at 5032 m - only in Tibet you can go higher.
Even at this extreme height, the Air 2D altitude kit did a great job. Fabian captured his test with a camera. Watch it here on Youtube.
So you can be sure that your heating won't let you down when it gets flaky up there.
Despite the altitude kit, the operation of a diesel parking heater (like a diesel engine in a vehicle) represents a technical compromise. In the long term, you have to ensure that the combustion chamber gets really hot again and can thus be burned free. Otherwise sooting cannot be avoided even with the altitude kit.
If you actually spend the night at 4000 m for several weeks, cleaning the combustion chamber and replacing the seals is possible and reasonable in terms of effort.
Burning off soot (also) at low altitudes
Burning off soot is the most important and, at the same time, only required maintenance of the heater. As at high altitudes, the combustion chamber must also be given the opportunity to get rid of incipient soot at normal altitudes.
Sooting generally occurs when the heating is running on a low power level. Therefore, let your heater run at full power for half an hour every 1 - 2 weeks.
Imagine the combustion chamber of your heating system like the engine of a diesel car - if it was only driven at low speeds, sooting must also be burned off with a decent drive on the motorway. The same applies to the combustion in the heater.
Autoterm parking heaters don't mind running an entire vacation and are extremely reliable. But should a repair be necessary, we are there for you as a service partner and Germany distributor with our own workshop. On long-distance or long-term trips, you could even carry out certain repairs yourself under our guidance if necessary - the heating does not have to be removed and sent in. This is another decisive advantage of Autoterm heating for travelers.
Important when operating at high altitudes
Lower maximum Output
At higher altitudes, the heater receives less air and, accordingly, less fuel. Accordingly, the maximum output of the heating decreases with increasing altitude. Roughly speaking: from 2000 m you lose approx. 5 % of performance for every 500 m.
Air intake - warm air outlet
Important: The clearance of the fan is of particular importance at great heights. It would be best to run the parking heater without hot air piping or just use a VERY simple one.
The combustion air intake and the exhaust pipe should be extremely short and with little resistance. Avoid kinks, blockages or reductions.
The Autoterm Air 2D can be controlled with various control units.
A simple control element with a rotary control, the PU-5. The heating is controlled here in power mode. If a temperature sensor is connected, the PU-5 also regulates in temperature mode (sensor must be ordered separately).
The newer variant is the PU-27 equipped with an OLED display. The control unit is digital and allows both, temperature control and the setting of a desired power level. The menu navigation of the PU-27 control unit is currently only available in English and Russian.
The new, improved "Comfort Control" panel for the Autoterm / Planar parking heater. With three freely adjustable timers for any day of the week, extended heating modes (incl. thermostat mode), voltage monitoring and much more. Multifunctional rotary wheel with pleasantly grippy rubber coating and OLED display. Smaller installation dimensions, more comfortable use, chicer design.
No temperature sensor is built into the PU-5 control unit; it must be ordered and installed separately.
PU-27 has an integrated temperature sensor. The cable of the control unit is 1.8 m long ex works. If it cannot be installed in a sensible place for temperature measurement, please order the external sensor and switch the temperature control to By_T_Air in the display.
The heater has an extra switching input on the wiring harness so that you can connect your own remote control. All you have to do is connect two cables using switches or relays. This happens either permanently, then the heating starts and runs until the connection is interrupted again, or with an impulse. A key pulse of 0.5-3 s length can be used for switching on. The next impulse would switch the heating off again.
The advantage of the second variant is that you then also have the option of controlling the heating with various control elements. So, for example, switch on with a self-made remote control or a button, then later adjust the power level from bed with the supplied control element or even switch it off.
All Autoterm heaters have an E-mark (e2). They can therefore be installed without registration, an approval by TÜV is not necessary.

Built-in docs and tips
When replacing Eberspächer or Webasto parking heaters
The pattern of the Autoterm heaters corresponds to that of the well-known parking heaters from Eberspächer and Webasto. A simple exchange can take place without having to drill new holes in the body of your car.
Autoterm Air 2D or 4D for double the performance?
You are here at the Autoterm Air 2D with 2 kW heating power. The Autoterm Air is also available as a 4D variant with 4 kW heating output in 12 or 24 V. Which dimensioning is right for you depends on your travel behavior, your destinations and the isolation of your vehicle. More is not = better in this case, even if the heating with twice as much output costs only marginally more!
4 kw turn smaller campers into a sauna very quickly, even at the lowest level, and you have to open the window when heating. This is not only completely unnecessary, it also makes your heating soot faster (see topic above).
If in doubt, choose the smaller heater and let it run at a higher level than always operate the large heater at the lower end of the scale!
