Benefits :

•  Coldflow 350 will significantly improve the cold weather performance of biodiesels.
• Coldflow 350 can be added 5 deg C above Biodiesel Cloud Point
• Mixing times vary depending on quality but generally a 10 minute mix with a re-circulation pump is more than sufficient.  If a mixing paddle is used a 5 minute mix is sufficient. 
• Coldflow 350 will prevent biodiesels made from RME, UCO, WVO blends from clouding and gelling at low  temperatures ot be added to fuel when temperature is above 55 deg C as product will flash off. Please note: should the biodiesel have other additives that are not supplied by Chemiphase Ltd then there may be further alterations to the predicted pour point.

Typical Dilution Rate’s of 3000ppm – 5000ppm (3 Litres – 5 Litres per 1000 Litres of Biodiesel)  Coldflow 350 must be added 5°C above Cloud Point of Biodiesel.

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 i.e. virgin vegetable seed oils have 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 350 additive  during all winter and spring months. Coldflow 350 has been specifically designed to modify the wax crystals, lowering the pour point of your bio-diesel  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 350 is generally dosed at 3000ppm / 3 Litres per 1000 Litres of biodiesel.  As you can see below if you bought a 20 Litre container of Coldflow 350 it would only add a 1.7 pence to the manufacturing cost of your biodiesel.  This enhancement would then enable biodiesel to perform at the lowest of UK temperatures, -17 deg C.
