Features & Advantages

  • Solves Diesel, MGO Cold Flow Problems.
  • Improves Low Temperature Operating Range.
  • Converts Summer Fuel to Winter Diesel.
  • Reduces CFPP (Cold Filter Plugging)

  • Compatible with all diesel fuels including pure bio-diesel.

After reefing ultra-low sulphur diesel contains natural waxes called paraffin wax. These tiny wax molecules are suspended in the fuel along with carbon molecules and other substances.

When the wax molecules are small, they can easily pass through a fuel filter and act as a lubricant for the injectors and fuel pump.

The problem with wax occurs as temperatures fall. Diesel has a cloud point, at temperatures lower than this the wax molecules start to grow crystals, as these grow they clump together (commonly called gelling) until eventually they are large enough to plug the fuel filter.

The temperature at which your filter plugs and flow  ceases is called the CFPP (Cold Filter Plug Point). 

The CFPP is very important,  if the temperature drops below this minimum temperature filters will block and fuel flow will stop, starving the engine of fuel.

The Cloud Point and the CFPP both vary depending on your location in the world and fuel quality from a particular refinery often this will vary from batch to batch.

To summarise - the waxes in diesel fuel bind together when temperatures fall, and get by growing crystals these paraffin waxes block the  fuel filters.


How To Use

Can be used with Bio-Diesel up to B20 (20% bio content). Reduces Cold Filter Plugging Point according to EN116 / IP309 and pour point according to IP15 / ISO3016. Hydra Winter Cold Flow is compatible with Hydra Fuel Plus Biocide. 

Hydra Winter Cold Flow must be added before the first crystal have formed, as any crystals already formed cannot be dissolved by the product.

Ideally Hydra Winter Cold Flow should be at room temperature and the diesel fuel being treated should not be below 0°C.

Dosage Rate

1,000ppm (1:1,000) can be increased to 2,000ppm (1:500) to give enhanced protection. Available in different pack sizes for ease of use, simply add to fuel when filling up. 

Add before refuelling.

Dilutions can vary depending on quality of your fuel as explained earlier and also your geographic location, you may have lower local temperatures that you need to protect to.

All our products are manufactured to the highest International Specifications at our UK plant.

This plant is accredited to ISO 9001:2008, ISO 14001:2004 and OHSAS 18001:2007 ensuring that EN 590:2009 fuel quality standard is always adhered to.

This product is excellent to avoid diesel fuel freezing. It gives my car a quick boost with the necessary energy needed to start up and run smooth.

I use this product especially when temperatures are below 0C. The start up works well and the engine runs a lot quieter. I highly recommend this product.

Freeze free
Sunday, 11 November 2018  | 

I have tried various winter additions in the past for my diesel tractor as they are meant to be fast acting but none have wowed me until I found Hydras winter cold flow additive. I need an add on so my tractor doesn't stop when in use for feeds and this product stops the diesel filter from freezing so for me I give it 5 stars.

Every year I have the same problem with the change over from summer fuel to winter fuel due to the tank still being half full and its just not possible to add enough winter fuel to avoid problems come the colder months. I came across Hydras winter fuel additive and have had no problems at all over winter.

Great additive for harsh winters
Sunday, 14 January 2018  | 

We have had harsh weather recently and my car has been having problems. I went to the filling station and filled my fuel tank up as well as adding winter cold flow additive. I drove around and my car is back to normal. I feel adding this product over winter really helps my old car out and has revived it for many more years. So if your car has issues during winter months, this is the product for you.

My vehicle often has problems in the morning with starting. I decided to look for an additive to help with this and found this product. It really does what it says, the car is much smoother and I have no problems with start up anymore.
