The Problem ...

Diesel fuel and biofuels gel at temperatures below freezing. Paraffin crystals form in the fuel, making it gelly-like and flaky. 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 system. 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 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 is a effective and permanent solution for cold problems with diesel or biofuels.

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

By controlled preheating of the fuel temperature-related operating problems will be effectively eliminated from the critical part of the fuel system and fuel additives are not required anymore.
 

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.

Installation

Diesel-Therm is as 12 and 24 Volt model in different versions available:

Screw-/Filterversion DH for filter inlet
	The Screw-/Filterversion DH is installed instead of the existing banjo screw (thread M14x1.5 or M16x1.5) at the filters entrance.
Universalversion DHS for rubber hose
	The Universalversion DHS is installed in the fuel line (flexible rubber hose) with 08, 10 or 13 mm inside diameter (ID) in front of the filters entrance.
Prices and Order
	Diesel-Therm is directly from ATG available. Following components are included in delivery: electric continuous-flow heater (12V approx. 200 W / 24V approx. 300 W), temperature switch (regulates the temperature), rotary switch with pilot lamp, relay, cable loom with connectors, fuse and protective caps, miscellaneous materials, detailed installation instructions

... we installed and tested several fuel heating systems. We decided to use Diesel-Therm. It is a very safe system, the heating is effective already after a short period of time. Within approximately 1 minute the troublesome smoke, which comes out of the exhaust pipe, vanishes. This is also a contribution to the environmental protection.
