Berol® 6446 HFO Fuel Emulsifier

Our unique technology is a major advancement in the fight against global warming. By using Berol® 6446 Fuel Emulsifier in all grades of HFO (Heavy Fuel Oils) you will significantly reduce toxic emissions, while saving your business a substantial amount of money on the wear and maintenance of your engines, burners, boilers and heat exchangers.

Remarkable, long-term stable emulsions of all grades of HFO are possible when combining Berol® 6446 HFO Fuel Emulsifier and our ultrasonic process equipment.

Product Expectations

Pre, during and post combustion expectations

Practical expectations and understanding the effects of using ultrasonically emulsified and stabilized fuel oil in burners.

Pre-Combustion Expectations

  • Less SOx and less NOx
  • Increased boiler availability


Understand the benefits of ultrasonically emulsified and stabilized fuel oil

The proprietary ultrasonic technology used in conjunction with Berol® 6446 HFO Emulsion Stabilizer plays a vital part in the process of substantially reducing toxic emissions and saving your business money through increased fuel efficiency and lower engine, burner and heat exchanger maintenance costs.

Ordinarily, heavy fuel oil (HFO) has to be heated to temperatures between 100c and 120c before it takes on liquid form, for use in the burners or in static generator engines, which not only costs a staggering amount of money, but also sees a loss of up to one fifth of the users’ HFO in the fuel-heating process. The savings on toxic waste emissions from the reduction of heating the HFO will be significant on a global scale.

SciMed/SulNOx/Hielscher trials and tests on The Berol® 6446 HFO Emulsifier showed that the product only needs to be heated to between 70-90c ( a reduction of 30 to 40c), meaning around 30% less fuel is needed for the heating process, which means less HFO is used or needed. Burning less fuel reduces toxic emissions and the Berol® 6446 HFO Emulsifier will naturally be 30-40% less polluting than any standard grade of HFO.

For around 100 years, companies have tried and failed to successfully create a stable ‘water-in-fuel’ emulsion. The Hielscher report shows, beyond doubt, that Berol® 6446 HFO Emulsion Stabilizer enables a remarkable, stable emulsion with up to 30% water added and as little as 1% Berol® 6446 HFO Emulsion Stabilizer (a stability that has shown a shelf-life in excess of 5 + years).

The SGS Certificate tells us that using Berol® 6446 HFO Emulsion Stabilizer in HFO 380 fuel reduces smoke and soot (particulate matter), NOx gases and sulphur emissions and that the strong acid value in the ash is zero. Choosing to use any of the SulNOx products will dramatically reduce ‘net emissions’, which is a huge step forward in the fight against global warming.
