At low temperatures, diesel fuel emits paraffin crystals suspended in the liquid.
As the concentration increases, the fuel filter can become clogged and the engine can even come to a standstill (diesel accumulation).
Contradictory additives for diesel are expensive, often not sufficient, partly polluting and dangerous. One thing, however, is quite clear: paraffin crystals, once formed, can only be removed by heat.
The solution is ThermoLine, a diesel fuel pre-heating system, which is installed in the fuel line to melt the paraffin crystals before reaching the primary filter
