The Autoterm Air 4D (formerly Planar 44D) is a 4kW diesel air heater by Autoterm (Advers). It's a reasonably priced alternative to similar models bei espar or Webasto, namely the Airtronic D4. The kit contains everything you need for installation, including a control unit and even a small fuel tank.
The control unit PU-5 allows for power level control. You can also attach an additional temperature sending in order to control by temperature mode.There is also a lead for external switches or self-made remotes.
All Planar heaters are (e2) mark certified allowing installtion in all vehicles within the European Union without consulting TÜV or MOT offices (or whatever they are called in your country.... ;)) Please not: The mounting holes etc. are identical to Espar, so you can simply replace one of those without having to modify anything.
