  • This product is classified as being a fully biodegradable product, non hazardous product.
  • This graph shows the increase in temperature performance levels of biodiesel's blended from Rapeseed feedstock.  1000ppm equates to 1 Litre of Coldflow 350 per 1000 Litres of biodiesel.  So 5000 ppm of Coldflow 350 added to biodiesel will allow the fuel to operate at -38 deg C.
  • This graph shows the increase in temperature performance levels of biodiesel's blended from Palm Methyl Ester feedstock 100%.  1000ppm equates to 1 Litre of Coldflow 350 per 1000 Litres of biodiesel.  So 5000 ppm of Coldflow 350 added to biodiesel will allow the fuel to operate at 8 deg C.
  • This graph shows the increase in temperature performance levels of biodiesel's blended from Soy Methyl Ester feedstock.  1000ppm equates to 1 Litre of Coldflow 350 per 1000 Litres of biodiesel.  So 5000 ppm of Coldflow 350 added to biodiesel will allow the fuel to operate at -8 deg C.
  • This graph shows the increase in temperature performance levels of biodiesel's blended from Used Cooking Oil feedstock.  1000ppm equates to 1 Litre of Coldflow 350 per 1000 Litres of biodiesel.  So 5000 ppm of Coldflow 350 added to biodiesel will allow the fuel to operate at -15 deg C.
  • This picture shows a standard biodiesel made from Used Cooking Oils.  As you can see the bottle on the left is without any additives and gelled at -1 deg C.  The bottle on the right contains Coldflow 350 at a rate of 4 Litres per 1000 Litres of Biodiesel.

 Product Description

Coldflow 350 - Biodiesel Winter Additive - "Biodiesel For Any Climate"

Coldflow 350 biodiesel additive will prevent biodiesel blends from clouding and gelling at low temperatures. Coldflow 350 is a biodiesel cold flow improver designed to be used from blends of Rapeseed Methyl Esters (RME), Used Cooking Oils (UCO), Waste Virgin Oils (WVO). Coldflow 350 will provide biodiesel cold weather protection and improve performance of storage and stability in biodiesels produced from blends of all ester based fuels. Coldflow 350 biodiesel additive will improve the biodiesel CFPP, the pour point of biodiesel, the point biodiesel begins to gel and improve the starting of biodiesel in cold morning's.

Coldflow 350 is highly effective on Biodiesel's made from :

  • Used Cooking Oils
  • Used Vegetable Oils
  • Rapeseed Oil (Waste or Virgin)
  • Soybean Oil (Waste or Virgin)
  • Mustard Seed Oil
  • Algae Oil
  • Recycled Oil's from restaurants, chip shops etc

Benefits of using Coldflow 350 on your biodiesel

  • Coldflow 350 biodiesel additive will significantly improve the cold weather performance of biodiesels.
  • Coldflow 350 biodiesel additive 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 to 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 Rates 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 Coldflow 350 works in the biodiesel

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 biodiesel additive 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.

Help and Advice for adding Coldflow 350

To achieve the lowest pour points of biodiesel using Coldflow 350/402 there are a few basics which must be adhered to allow your fuel to reach low pour points which in turn will help your biodiesel run through the winter.

Coldflow 350 is a biodiesel winter additive for biodiesel blends made from good quality oils like used cooking oils which contain less than 10% palm oils or heavy oils.

Coldflow 402 is for biodiesel’s made from 10% or more Palm oils or other heavy oils with poor pour points.

  1. Do not add the Coldflow biodiesel additive products to your biodiesel when it is already cold. The chemistry behind the Coldflow range poison’s the sites where crystals are forming in the fuel and delays this from happening until a much lower temperature has been achieved.  This will not happen if there are crystals currently formed in the fuel as they have already been formed.
  2. For the best results when adding the Coldflow range the biodiesel must be at least 5 degC above the pour point of the fuel. To gauge the pour point of your fuel it's a simple test. Take a sample of your fuel when produced and leave in a freezer and let it begin to freeze. As the biodiesel freezes you will see clouding occur which is the beginning of the crystals forming. At this point take a temperature reading and add 5 deg C. This is the pour point of your fuel.
  3. Now you have the optimum temperature for your biodiesel to blend the Coldflow into your fuel.
  4. To achieve the best results you must mix the Coldflow’s into the fuel very thoroughly. To do this we recommend either a mixing paddle or a recirculation pump. If you are using a re-circulation pump we suggest adding the Coldflow to the fuel and re-circulating for at least 20 minutes to ensure the product has mixed into the solution.
  5. The Coldflow range has a particle size sub 1 micron so will easily pass through 1 micron filters. We do suggest though that if you are centrifuging your biodiesel after adding the Coldflow it does have the potential to be removed. So if possible centrifuge the biodiesel before you add the Coldflow’s.
  6. Dilution rates, as mentioned earlier we suggest ascertaining the level that you biodiesel begins to gel to achieve a baseline for your fuel. We then recommend running small-scale lab tests with different dilutions to achieve a level that suits your fuel. Chemiphase recommends a dilution rate of between 3 & 5 Litres of Coldflow’s per 1000 Litres of biodiesel. Try a small-scale 3:1000 Litre sample, a 4:1000 Litre sample and a 5:1000Litre sample to see the benefits of adding a little bit more. You may find the 5 Litre per1000 Litres of biodiesel achieves -25 deg C and may be far too high for the UK. If this is the case you may be happier using a 3 Litre per 1000.
  7. If you are blending your biodiesel with mineral diesel the Coldflow range will act as a winter additive for the biodiesel and the mineral diesel.  All biodiesel additive products must be stored away from children.

 Product Reviews

  1. Winter without problems

    Posted by Paolo on 11th Sep 2014

    A really good item for use my bio without problems of freezing through the next winter.


  2. Good Service

    Posted by LR Porter on 7th Mar 2011

    Good, rapid delivery. Reasonable price. Very poor, non-functioning email comms.


  3. Tested my fuel down to minus 18 deg C

    Posted by Lloyd Jones on 3rd Mar 2011

    I was having massive problems with biodiesel gelling at low temperatures. I was recommeded Coldflow 350 by a friend in the biodiesel world and wow was i impressed! By adding 4 Litres per 1000 Litres of fuel i could now get my fuel to run at -18 deg C. Very very happy!
