Coldflow 402 - Biodiesel Winter Additive - "Designed For PME, SME Biodiesel Blends In Winter"

Coldflow 402 is a coldflow improver for biodiesels made from heavier animal fats i.e. palm, tallow.  Biodiesels made from Palm Methyl Esters & Tallow Methyl Esters have much higher gelling points in comparison to standard diesels.  This is where Coldflow 402 has revolutionised the market, with very small dilution rates of Coldflow 402 to biodiesel, many of our customers have been able to achieve excellent results with the minimal dilution rate of 3 Litres per 1000 Litres of biodiesel.  Coldflow 402 offers the biodiesel producer the comfort knowing that their biodiesel wont be affected by cold weather conditions.

Coldflow 402 is highly effective on biodiesel made from :

• Palm based biodiesels (Greater than 25% Palm)
• Tallow based biodiesels
• Yellow Grease biodiesel blends

Typical dilution rates vary from 5000ppm (5 Litres) of Coldflow 402 to 10000ppm (10 Litres) per 1000 Litres of Biodiesel.  The dilution rates vary due to the quality of the biodiesel.  We recommend customers test the product themselves using 5000ppm - 10000ppm and achieve the dosage levels that best suits them and there customers

How it Works: 

Biodiesel will cloud like petroleum diesel fuel when the weather gets cold. Initially we see little crystals of wax forming and these crystals will begin to clog fuel filters. When it becomes colder still, the biodiesel will form into a gel that will eventually set solid.  Depending on the type of oils used to make your biodiesel ie. virgin rape seed oil has a lower pour-point (or CFPP -- Cold-Filter Plugging Point) than used cooking oil (UCO, WVO) mixtures. This is due to the level of saturation, or number of hydrogen atoms present. This is determined by the Iodine value. Generally the higher the Iodine value of the oil, the biodiesel esters produced will take on a lower pour point.   To avoid this problem we suggest your produced biodiesel is treated with ColdFlow 402, flow improver additive that has been specifically designed to modify the wax crystals, lowering the pour point of the fuel.

Coldflow 350 or Coldflow 402 for my biodiesel ?

Generally if your biodiesel begins to cloud and gel at or above 10 deg C then you need Coldflow 402.  If your biodiesel begins to cloud and gel below 10 deg C you need Coldflow 350.

Coldflow 402 Performance :

Coldflow 402 is generally dosed at 4000ppm / 4 Litres per 1000 Litres of biodiesel.  As you can see below if you bought a 20 Litre container of Coldflow 402 it would only add a 2.5 pence to the manufacturing cost of your biodiesel.
