1. Wide application: Diesel air heaters can be used for heating various dieselpowered vehicles such as cars, trucks, caravans, lorries, technical vehicles, boats, touring cars, buses, and yachts. They are also suitable for indoor use in small spaces, such as homes, warehouses, factories, and offices. 2. Extended LCD and remote control: The remote control allows for preheating; oil quantity, temperature, and wind speed can be adjusted; and window frost can be removed. The LCD controller screen comes with a protective film! Fuel pumps are tested during production, so there may be a small amount of fuel inside. 3. Automatic and volatile technology: The 1inch auxiliary heater uses advanced automatic control technology, ensuring reliable operation under abnormal conditions. It preheats the engine coolant to prevent engine wear at low temperatures. Thanks to volatile technology and the ceramic ignition plug, fuel is vaporized into gas for fast ignition and complete combustion. 4. Easy to install: The 12V diesel heater has a compact structure, making installation simple. When changing vehicles, it can be easily transferred to a car. Fuel, electricity, and temperature can be adjusted as desired.
