Product details

The 4D DELUXE URAL EDITION auxilliary diesel air heater from Autoterm Air is perfect for larger boats from 7.5 m. The digital control panel (including temperature sensor) makes it extremely easy to adjust power levels and temperature. The air heater is certified (e2) and can be installed without registration. The hole dimensions are identical to those of the popular Webasto or Erberspächer heaters, so it is easy to replace without having to drill new holes. Delivery includes an altitude kit, an exhaust silencer, an additional tank and all the components needed for installation. A minimum diameter of 90 mm is recommended for connecting hot air pipes. The connection adapter for the warm air side to reduce from 96 mm to the standard dimension of 90 mm is not included in the delivery.

The heater's cable harness features a gate input for connecting your own remote control or other secondary control unit. You can choose whether the connection is made via ON/OFF switch or pulse. The advantage of the latter means that it is possible to operate the heater with different controllers. For example, you can switch on with a remote control or a push-button and later adjust power levels or even switch off from your bed using the included control element.

In addition, the air heater is equipped with a so-called altitude kit. Thanks to this altitude kit, the heater automatically reduces the quantity of fuel injected depending on the ambient air pressure. This prevents or drastically reduces the likelihood of the combustion chamber from clogging with carbon particulate in the event of a falling air oxygen content.

Maintenance is not normally necessary. However, to prolong service life the combustion chamber must be allowed to get really hot from time to time to burn off any residues. As a rule, running the heater at full power for at least half an hour once every week or every two weeks is enough to allow the combustion chamber to reach full temperature again.

Schnell und gut
Der Einsatz im großen Reisemobil ist optimal und bringt eine schnelle Wärmeverteilung, duch das integrierte und einstellbare Gebläse mit Heizleistungsregulierung.
Der Selbsteinbau ist mit etwas handwerklichem Geschick schnell erledigt, wenn man den passenden Einbauort im Fahrzeug lokalisiert hat.
Je nach Plazierung im Fahrzeug, können die Gebläsegeräusche in den hohen Leistungsstufen schon mal etwas stören. Der minimale Kraftstoffverbrauch beeinträchtigt das Reisegefährt in keinster Weise.
