Watch - Sulnox, Making Fuel go Further

Sulnox Eco fuel conditioner is an organic, drop-in solution for more complete combustion and improved engine function – applicable to all liquid hydrocarbon fuels.

sulnox eco brandmark midnightSulnox has been scientifically developed over the past 10 years by a global leading team with over 60+ years experience in the emulsion fuels industry. Delivering both improved performance AND huge ecological benefits, it represent a unique and rewarding opportunity for business.

Sulnox reduces fuel and maintenance costs by making hydrocarbon fuels burn more efficiently – even more importantly through its unique technology, it simultaneously achieves a significant reduction in toxic emissions and helps to reduce particulate matter.

Unlike many traditional additives that rely on waste fossil fuel components or cetane boosters, Sulnox Eco enhances combustion
efficiency - helping to reduce emissions, improve fuel economy, and protect engines while keeping fuel within specification.

How Sulnox Works - Four Mechanisms:

1          Emulsification
Disperses free water into microscopic droplets within the fuel

2        Secondary Atomisation
Fragments larger fuel droplets through micro-explosions to increase surface area and deliver more complete combustion

3        Detergency
Cleans and decarbonises vital engine components for improved operation

4        Lubricity
Reduces friction dramatically to lower wear and maintenance costs

Sulnox is delivering significant results...

When adopted across a fleet of engines, Sulnox Eco delivers major fuel savings and emission cuts - Typical fuel savings of 8% in Land Applications

Sulnox Eco outperforms Traditional Additives

Unlike many traditional additives that rely on waste fossil fuel components or cetane boosters, Sulnox Eco enhances combustion efficiency - helping to reduce emissions, improve fuel economy, and protect engines while keeping fuel within specification.

HOW IT WORKS

Additive

Often relies on cetane boosters or waste fossil fuel components.

fossil fuel icon

Sulnox

Atomises fuel into smaller particles for cleaner combustion (secondary atomisation).

tick icon
COMPOSITION

Additive

Often petroleum-derived or
metal-based.

petrol based icon

Sulnox

100% organic, biodegradable, no fossil waste or metals.

tick icon
LUBRICITY & CLEANING

Additive

Many do not improve lubricity,
some increase wear.

engine icon

Sulnox

Adds average 17% lubricity,
reduces wear & cleans engine.

tick icon
EASE OF USE

Additive

Often fuel-specific, some require
hardware.

ppe icon

Sulnox

Works in any liquid fuel, no
retrofits needed.

EMISSIONS REDUCTION

Additive

May enhance combustion but does little to reduce soot, particulates, or other emissions.

fossil fuel icon

Sulnox

Over 96% fewer particulates, 26% less CO₂, 14% less NOx, and 64% less SOx*.

sulnox eco

Sulnox Eco Fuel Conditioner is a green product made with organic ingredients, is readily biodegradable and compatible with all diesel and other fuels, including biofuels.

Combined benefits of Sulnox Eco can allow users to achieve an overall reduction in fleet operating costs by up to 14.5%*

Benefits of Sulnox Eco Fuel Conditioner include:

  • Simply add Sulnox Eco™ to the fuel tank before filling up with fuel and Sulnox Eco will scavenge free water from your system – the resultant homogenous fuel will remain stable for months in the tank
  • Sulnox Eco reduces corrosion, clears residue and improves efficiency - in so
    doing it heavily reduces emissions as well as significantly reducing fuel costs
    whilst remaining fully compliant
  • Lubricity improved by c17% which helps maintain the condition of fuel pumps and injectors – a substantial reduction in engine wear and maintenance costs
  • Engine oil and bearing life is improved by reduction of the soot and acid byproducts of combustion
  • Mix Ratios:
    1:1,000 for gasoline/petrol
    1:2,000 for diesel/biodiesel/HVO/MDO/MGO/HFO

Pre, During and Post Combustion Expectations

  • Offers a more complete combustion - which leads to particulate matter
    reduction (PMs).
  • Lower exhaust temperature
  • Significantly reduced nitrous oxides (Nox) formation
  • Significant reduction of the need for Exhaust Gas Recirculation (EGR)
  • Any grade of fuel being used will produce less soot - extending engine life
  • Reduces contamination of engine oil – preserving the engine
  • Reduced fouling of Diesel Particulate Filter
  • Less visible smoke and reduced fouling of ignition and fuelling components
  • Improved combustion efficiency – improved fuel economy
  • Lower sulphur oxides (Sox) and less acidic products of combustion
  • Reduced engine parts corrosion, reduced failure of lubricating films
  • Longer turbo life and reduced engine maintenance
