The Problem ...

Diesel fuel and biofuels gel at temperatures below freezing. Paraffin crystals form in the fuel, making it gelly-like and cloudy. As these suspended flakes pass through the filter, they gum up its microporous surface. Within a short period of time, the fuel will no longer flow through the filter to the injection pump. The results: the engine loses power and stops running. Adding gasoline or additives to prevent fuel gelling offers no real solution but only seem to help on a limited basis. They can have a negative effect on the engine´s performance and life cycle, not to mention, they must already be added before it turns cold.

"Winter diesel" (formulated especially for winter usage) does not guarantee a smooth running engine. Winter diesel is
laboratory tested to -20° C / -4° F. At still lower temperatures and/or freezing winds, it is unclear whether the engine
will even run. In any case, the engine works unregularly, resulting in a greater amount of fuel being consumed.

Once the fuel filter is clogged, only the supply of warmth can solve the problem quickly. By heating, the engine is
protected when running on any fuel at any temperature and prevents greater fuel consumption.

... The Solution

The Diesel-Therm fuel preheater offers a effective and above all else, a permanent solution for this problem.

Diesel-Therm prevents the filter´s pores from clogging up at very low temperatures by warming the fuel with
a small heating system, which is mounted in front of the filter. In a matter of seconds, the energy-rich paraffin
crystals will dissolve and the fuel passes through the filter as if it would be summer.

Diesel-Therm - filter heater

Fuel additives can be done completely away with by installing Diesel-Therm. With it, temperature-related operating
problems will be effectively eliminated from the fuel system.
 

To prevent cold problems or a loss of power due to a plugged fuel filter Diesel-Therm is activated by the driver with a On-/Off-switch. The heating process is displayed by a pilot lamp and automatically regulated by a thermostat. The heating of the fuel remains as long as the heating device is deactivated over the switch.

Alternative to the fuel filter Diesel-Therm can also be installed in front of fuel pumps, solenoid valves, etc. to
preheat the fuel.

FAQ - Frequently Asked Questions

Which Diesel-Therm-Version fits to my vehicle?

Due to the vast number of vehicles or engines on the market, it is almost impossible to make a type-specific statement.

• If there exists a banjo screw with wrench size 19 at the filters entrance, the screw-/filter version with thread size M14x1.5 fits.
• If there exists a banjo screw with wrench size 22 at the filters entrance, the screw-/filter version with thread size M16x1.5 fits.

• If there exists no banjo screw at the filters entrance, the universal version with connectors for the fuel lines has to be used.

In case of doubt we recommend the universal version (fits all).

Where can I have Diesel-Therm installed?

The installation ca be performed by any reputable garage/mechanic.  Craftmanship and an understanding of diesel engines provided, a DIY (do-it-yourself) installation with the included installation notes is also possible.

Is the electrical preheating of fuel generally allowed?

For your own protection, please check with the appropriate authorities in your country. This is also to be done for any changes on the vehicle.
