NanoEFX for mining & quarrying

NanoEFX is a passive, water-based air-filter treatment for combustion engines with a treatable air filter or intake medium. It can be applied to mining engines where such a filter or medium is present. We have not yet run a mining-sector trial, however, and the closest loader evidence in our records was negative — so the magnitude of any effect should be measured under the mine's own operating conditions.

What it is

A coating on the air filter — not a fuel additive or a remap

NanoEFX is sprayed onto the engine's air filter — the existing one, or a replacement filter treated in advance — where it dries into a thin, breathable nano-coating. As the engine draws air through that treated surface, the coating is designed to condition the intake air before combustion, with the aim of supporting a cleaner, more complete burn — what we have measured is set out below. For a mine fleet, that means the same treatment can be applied to every engine that breathes through a treatable filter — whether it lowers fuel use on a given engine is what a pilot measures.

What it is

  • A passive nanostructured intake-air treatment
  • Applied to the engine’s air filter
  • Water-based — dries to a thin, breathable coating
  • Works before combustion, at the intake-air stage

What it isn't

  • A fuel additive or oil additive
  • An ECU remap or tuning
  • A mechanical retrofit or powered device
  • Anything that changes how you operate

Why it matters

Three pressures every mine operator already feels

These are the forces that make intake-air efficiency worth acting on — independent of any single engine or duty cycle.

Diesel is one of a mine’s biggest costs

Haul fleets and mobile plant burn enormous volumes of diesel, so fuel is a dominant operating cost. If a pilot measures a gain that holds over a representative period, even a small percentage could mean a large absolute saving over huge run-hours; whether it carries over to other machines is checked separately.

Decarbonisation pressure in mining

Miners face investor and stakeholder pressure to cut Scope 1 diesel emissions. A more complete burn is the aim — less fuel wasted, without replacing the engine; measured results vary by machine and duty cycle.

Remote fuel logistics

Fuel is expensive and complex to deliver to remote sites. Using less has outsized value where every litre has already cost a great deal to get there.

What we have not measured

No trial data from this sector

We have not run a trial in mining. Rather than borrow a number from another sector, here is exactly what we do and do not hold.

The nearest evidence we hold

The closest equipment in our records is heavy haulage and loaders. Two 10 tonne tippers improved by around 6% in fuel efficiency measured in km/L, and both loaders we have measured lost fuel efficiency after treatment. Loaders and haul trucks share the high-load, low-speed, heavily variable duty that mining runs on, so that negative result is the more relevant of the two — and it is a caution, not a selling point.

What a trial here would have to look like

A mining trial we would trust needs untreated sister machines working the same benches over the same weeks, fuel drawn from the same bowser, and payload logged per cycle. Without payload data a haul-truck comparison measures the pit plan, not the engine.

Relevant to remote site power: telecom generators running continuously at near-zero load showed a median of +1.7% — too small to establish a clear effect for that duty cycle.

What it covers

From a haul truck to a site compressor

A mine is rarely one machine. NanoEFX can be applied to mining engines that breathe through a treatable air filter, and it works at the intake air, whatever the fuel burned.

Equipment types

Haul trucks Crushers & screeners Drilling rigs Industrial pumps Compressors

Fuels

Diesel Biodiesel (no field validation) HVO renewable diesel (no field validation)

For the fuels marked above we have no documented field validation, so we make no performance claim for them.

How it's applied

No workshop, no retrofit, no new hardware

Your own team either fits a pre-treated filter, or treats the existing filter, lets it dry for at least 20 minutes and refits it.

Application is a spray onto the existing air filter — no new parts, no calibration, no mechanic. It dries to a thin, breathable coating and the filter is refitted. Alternatively, a pre-treated filter is fitted.

What this could mean for a mine fleet

Lower fuel spend — measured as fuel saved in your own pilot.
Lower CO₂ for ESG reporting — burning less fuel lowers your Scope 1 emissions as calculated from fuel consumption.
More complete combustion would generally reduce CO and unburned hydrocarbons; our one accredited exhaust measurement recorded lower CO, HC and NOx on one vehicle.

NanoEFX doesn't add energy or oxygen and doesn't modify your engine — it is designed to help the engine waste less of the energy already in the fuel. NOx response is engine- and control-system dependent.

Mining — FAQ

Common questions from operators

Can NanoEFX be used on our haul trucks and heavy diesel plant — and what can we expect?
NanoEFX can be applied where the engine draws intake air through a treatable filter or intake medium. We have not yet run a mining-sector trial, however, and the closest loader evidence in our records was negative. Mining duty cycles vary heavily with payload, route and operating conditions, so any fuel effect should be validated on the operator's own equipment.
Do our engines need any changes or an ECU remap for NanoEFX?
No. NanoEFX is a passive coating on the air filter. It is not a fuel additive, an oil additive, an ECU remap or a mechanical retrofit, and it makes no change to the engine’s hardware or software.
How often does NanoEFX need reapplying on a haul fleet?
Reapplication is calculated by run-hours and engine size rather than distance, because mining plant is measured in operating hours. Your own team either fits a pre-treated filter, or treats the existing filter, lets it dry for at least 20 minutes and refits it.
Does NanoEFX help cut diesel emissions and support ESG targets?
Burning less fuel lowers Scope 1 diesel emissions as calculated from fuel consumption; combustion theory would expect less CO and unburned hydrocarbons from a more complete burn, but we hold one accredited measurement on one vehicle and none on soot. NanoEFX is not itself a certification and NOx response is engine-dependent, so it complements your other measures.
Does NanoEFX affect the DPF, SCR, EGR or AdBlue system?
We have not measured it, and we will not tell you it is proven safe for your aftertreatment system. What is established is what the treatment is and is not: a passive coating on the filter medium — not a fuel additive, not an oil additive, not an ECU remap and not a retrofit — so nothing is dosed into the fuel or the oil. What the coating does contain is silver and mineral particles, and they sit on the filter surface, in the intake path. Whether any of that material is carried downstream in service is not something we have measured, and neither is anything else that would settle the question for you: DPF ash loading, regeneration frequency, EGR valve and cooler fouling, AdBlue/DEF consumption, SCR conversion efficiency, or lambda and NOx sensor behaviour. None of the 386 individual measurements we hold records any of them. What we can state is that nothing applied to an air filter changes a vehicle’s type-approval category — Euro VI, Stage V and Tier 4 depend on the engine and its aftertreatment. If you run aftertreatment-equipped vehicles, put those readings into the pilot and measure them alongside fuel.
Prove it on your own fleet

Don't take the claim — measure it

The most honest evidence is your own baseline. In a NanoEFX pilot you run a controlled trial on your own engines, measured against your own fuel data — and you only pay if it proves savings.
