NanoEFX for construction & heavy equipment
NanoEFX is a passive, water-based air-filter treatment for combustion engines with a treatable intake filter or medium. Results across documented applications give us reason to expect an effect in suitable construction machinery, but duty cycle matters. Our construction-relevant evidence is mixed: heavy tippers improved by around 6% in fuel efficiency measured in km/L, while the loader results in our records were negative.

A coating on the air filter — not a fuel additive or a remap
NanoEFX is sprayed onto the engine's existing air filter, where it dries into a thin, breathable nano-coating. As the engine draws air through that treated surface, the coating conditions the intake air before combustion — supporting a cleaner, more complete and more efficient burn. For a plant fleet, that means the same treatment works across every engine that breathes through a treatable filter.
What it is
- A passive nanostructured intake-air treatment
- Applied to the air filter you already service
- 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 site operator already feels
These are the forces that make intake-air efficiency worth acting on — independent of any single engine or duty cycle.
Off-road diesel is a major project cost
Heavy machinery is fuel-intensive, and fuel is a large, controllable line in the project budget. Because the effect repeats across every operating hour, even a modest efficiency gain accumulates across a fleet.
Non-road emission standards and clean-air zones
Non-road mobile machinery falls under tightening emission standards such as EU Stage V, and cities increasingly restrict higher-emission plant. A more complete burn means less CO, unburned hydrocarbons and soot.
ESG expectations on tenders
Contractors are increasingly asked to measure and report site emissions. Burning less fuel directly lowers the Scope 1 emissions reported for a project.

Our own trials in this duty cycle
Our construction-relevant records are tippers and heavy haulage on the one hand, and loaders on the other — and those two groups did not behave the same way. Both are shown.
What this duty cycle actually consumes
The 10 tonne tippers in our records run at 1.97 to 2.15 km/L before treatment. At that consumption level a small percentage moves a large quantity of diesel, which is why the calculated CO₂ effect on this equipment is bigger than on vehicles with far larger percentage gains.

From a 40-tonne excavator to a site compressor
A site is rarely one machine. NanoEFX applies to construction engines that breathe through a treatable air filter, and it conditions the intake air regardless of the fuel burned.
Equipment types
Fuels
No workshop, no downtime, no new hardware
NanoEFX is applied by your own team, onto the air filter they already remove at service. It rides on the maintenance you do anyway rather than adding a new one.
What a cleaner burn means for a plant fleet
NanoEFX doesn't add energy or oxygen and doesn't modify your engine — it helps the engine waste less of the energy already in the fuel. NOx response is engine- and control-system dependent.
Common questions from operators
Does NanoEFX work on off-road diesel machinery?
Will it change the engine or need an ECU remap?
How often does it need reapplying on machinery?
Does it help with Stage V and low-emission construction zones?
Does it affect a 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.
