NanoEFX for power generation
NanoEFX is a passive, water-based air-filter treatment for combustion engines with a treatable intake filter or medium. Results across documented combustion applications give us reason to expect an effect under suitable operating conditions, but load and duty cycle matter. Our eleven-site telecom-generator trial produced a small positive median fuel-saving result of 1.7%, with site results ranging from −1.6% to +5.7%; that result was too small and variable to establish a clear treatment effect for the duty cycle tested. Separate heavy-oil boiler applications under real heat demand produced substantially stronger positive results.

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 generator 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 power operator already feels
These are the forces that make intake-air efficiency worth acting on — independent of any single engine or duty cycle.
Fuel is the cost of every running hour
For prime power and long run-hours, fuel is the dominant operating cost of a genset. Because the effect repeats every hour the engine runs, even a modest efficiency gain accumulates quickly.
Air-quality permits and emissions limits
Gensets and power sites operate under emissions permits and local air-quality rules. A more complete burn means less CO, unburned hydrocarbons and soot, without replacing the engine or retrofitting hardware.
Carbon reporting on on-site generation
Organisations increasingly measure, report and price the Scope 1 emissions from their own generation. Burning less fuel directly lowers both the fuel cost and the reported carbon.

Our own trials in this duty cycle
This is the duty cycle with our most limited result. Our eleven-site generator trial produced a small positive median but no clear treatment effect — and our stationary boiler data, on plant that carries real load, is among the most consistent we hold. Both belong on this page.
What this duty cycle actually consumes
The generator sites in our Nigerian trial consumed between 8 and 114 litres per day each; the heavy-oil boilers in our Japanese record between 21,500 and 37,300 litres per month. The difference in outcome between the two is the thing worth understanding before treating any stationary plant.

From prime and backup gensets to CHP
Power generation is rarely one engine. NanoEFX applies to generator 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 generator 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 diesel and gas gensets?
Will it change the engine or its controls?
How often does it need reapplying on a genset?
Does it help with emissions permits and reporting?
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.
