Middle distillates also known as Diesel fuels are typically produced through a refining and distillation process from crude petroleum oils. Typically diesel fuels are a mixture of paraffinic, aromatic & olefinic hydrocarbons and are on the heavy end of the crude oil barrel. Cold weather presents unique challenges for fuel operations. As the temperature drops below its cloud point, the normal paraffin’s in the C10 to C25 range present in the fuel start to come out of the solution as wax crystals.

In diesel vehicle fuel systems, the presence of such long interlocked crystal structures would also cause operational difficulties, as they would quickly plug fuel lines & fuel filters. If the temperature is sufficiently low to crystallize a lot of wax, the engine would simply stop through fuel starvation. Increasing the aromatics component in the fuel composition by blending lighter, kerosene type components would not be the best solutions, as it would increase cost & lower its cetane value & fuel lubricity. Besides, such blends demand higher price when sold for use in aviation fuel. KAPL is a manufacturer of Pour Point Depressants additives for Fuel Oil.

CRISTOL Pour Point Depressants for fuel oil have enabled fuel to operate satisfactory at temperatures below their cloud point. These pour point depressant additives are cost-effective solutions to ensure smooth flow of the fuel and prevent fuel filter problems caused by separated paraffin’s. The function of these pour point depressants is to interact with the wax crystals, modify their growth, reduce their shape & size, prevent them to form agglomerates & also reduce the temperature at which they crystallize.


  • Reduces Pour Point substantially
  • Reduces need to use kerosene for Pour Point Reduction.
  • Completely organic and ash-free.
  • Contains no metal, halogens or sulfur.
  • Does not affect the Cetane index or aromatic content of the fuel.
  • Enables deeper cut into the barrel for middle distillate use.
  • Broadens range of crude oil useable for middle distillate production
