In 1983, a cold year, Michel DEBEAUX filed a patent and sold diesel heaters whose main interest is that they work without electricity.
In colder countries, our heaters have proven their effectiveness for starting and driving diesel vehicles in cold weather. The motor always starts, but within minutes diesel cars not equipped with a heater stop.
Many users, including Renault Trucks, are equipped with our devices. Heating is as fast as an electric device (which is also placed before the filter) and more powerful 2000W returned as electrical appliances are only 100W to 500W maximum which is a lot in 12 Volt and penalises the battery a time when it is most needed. With our devices, electricity consumption is zero.
