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.

|---|---|
| Applies to | Haul trucks · Crushers & screeners · Drilling rigs · Industrial pumps · Compressors |
| Fuels | Diesel · Biodiesel (no field validation) · HVO renewable diesel (no field validation) |
| Application | Existing filter treated (20–45 min) or pre-treated filter fitted |
| Reapplication | By run-hours & engine size (mining plant is measured in operating hours) |
| Engine changes | None — no modification, remap or retrofit |
| Regulatory context | EU Stage V engine-emission standards (non-road mobile machinery) |
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
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.

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.

How a trial is run and what each method can show: measurement methodology. What we measured at the exhaust: emissions. Everything in one place: the evidence section.
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
Fuels
For the fuels marked above we have no documented field validation, so we make no performance claim for them.
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.
What this could mean for a mine fleet
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.
Common questions from operators
Can NanoEFX be used on our haul trucks and heavy diesel plant — and what can we expect?
Do our engines need any changes or an ECU remap for NanoEFX?
How often does NanoEFX need reapplying on a haul fleet?
Does NanoEFX help cut diesel emissions and support ESG targets?
Does NanoEFX affect the DPF, SCR, EGR or AdBlue system?
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.
