The cold flow behaviour of diesel fuels usually depends on their molecular structure. As the fuel is cooled n-paraffins tend to form crystals, coalesce and settle out of the fuel. This causes blocking of the engine filters. The right type of CFPP improver can delay this phenomenon and make sure the wax crystals do not settle. Based on experience, WRT has developed a wide range of CFPP improvers.
Our additives improve the cold flow properties of diesel fuels like gas oil, (bio-)diesel and marine diesel oil.
