§ 01 — The value
Why NTROPYX®
Four things competitors cannot copy.
A true catalyst, not an additive. Compatible with every hydrocarbon fuel. Measured savings — not marketing. Engineered and produced in Switzerland since 2014.
A catalyst, not an additive
Enables complete oxidation at the molecular level without being consumed or altering the fuel chemistry. Leaves the tank cleaner than it found it.

§ 04 — The payback
ROI simulator
Your fleet, your fuel, your payback.
Move the sliders. See what an 8–12% molecular catalyst does to your annual fuel bill — before you ever commit to a pilot.
Commercial logic, short version. NTROPYX is priced as a fraction of the fuel it treats. A fleet burning €3–5 M of diesel per year recovers the annual catalyst cost in the first two to three weeks of the contract — the remaining fifty weeks are pure margin recovery.
Most operators measure the difference in the first tank-to-tank cycle: a dosing log, a calibrated fuel meter, and an odometer are enough to see the delta.

§ 05 — The markets
Where NTROPYX runs
Six sectors. One molecular catalyst.
Fuel is the same molecule everywhere; the economics change per sector. NTROPYX is calibrated for each one, priced on the volume it treats, and sold per programme — never as a one-off drum.
Road Freight

§ 06 — The science, one page
How it works
Three steps. No mystery.
NTROPYX is not a story. It is a chemical reaction — and a measurable one. Here is what happens inside the combustion chamber, in plain language.
· 01 ·
Molecular rearrangement
NTROPYX rearranges fuel molecules at the molecular level, increasing surface area and oxygen accessibility for each hydrocarbon molecule in the combustion chamber.
· 02 ·
Increased oxygen bonding
Carbon atoms bond with more oxygen molecules, enabling a more complete oxidation reaction. Unburned fuel is eliminated; PM, NOx and CO emissions drop.
· 03 ·
Bridge technology
Whether automotive, industrial, marine, or heavy-duty, NTROPYX delivers a vital bridge technology towards cleaner, more sustainable combustion — today, not in 2050.
§ 07 — The operators
Field voices
What the people who measure the fuel say.
NTROPYX is bought by fleet directors, chief engineers and procurement leads — not marketing teams. These are the words we hear once the first tank-to-tank cycle is logged.
We ran the pilot on two tractor units for six weeks. The delta held at 9.6% average. Rolled it out across the long-haul fleet in the next quarter.

SFOC reduction was the number we watched. Chief engineer called it out on day four. Particulates on the scavenge air pipes dropped visibly.

Our gensets ran cleaner and we stretched the oil-change interval by 15%. We didn't budget for maintenance savings — they came anyway.

§ 08 — The programme
How it's sold
Three programmes. One chemistry.
NTROPYX is sold per programme, not per drum. Pricing scales with the volume of fuel the catalyst treats, not with cosmetic packaging. All programmes include SDS, dosing protocol, pilot tracking and field support.

§ 10 — The sceptic
Honest FAQ
The ten questions procurement asks first.
Every serious buyer opens with the same list. Here are direct, non-marketing answers — written by the technical team, not the sales team.
Is NTROPYX a fuel additive?
No. NTROPYX is a molecular combustion catalyst. It does not change the fuel chemistry and is not consumed during combustion — it enables a more complete oxidation of the existing hydrocarbon fuel. Active concentration in treated fuel is below 20 ppm.
Does it void engine warranty?
NTROPYX is formulated to meet the fuel specifications recognised by major engine manufacturers. We supply an SDS, a technical datasheet and the dosing protocol so your OEM and insurance teams can review. Operators in our programme have not experienced warranty issues; we cooperate directly with OEM technical departments where relevant.
What fuels is it compatible with?
Every hydrocarbon fuel in commercial use: diesel, gasoline, HVO, biodiesel up to B100, HSFO 3.5% and VLSFO 0.5%, MGO, MDO, IFO380, heating oil and kerosene.
How is it dosed?
At point-of-fill, into the bunker barge, the road tanker or the on-site storage tank. No injector hardware, no engine re-mapping. Pilot dosing is supervised by our technical team; operational dosing is automated or manual, depending on the site.
Who certifies the test results?
Engine bench and emission test reports referenced on this site are issued by a Chinese laboratory accredited under CNAS L23122, recognised through ILAC-MRA, and carrying the CMA mark (China Metrology Accreditation, 202419120184). These are accreditations of the issuing laboratory — not of NTROPYX or Virgo Global Energy.
How is it priced?
Per programme, not per drum. Pricing scales with the annual fuel volume the catalyst is designed to treat. A typical fleet recovers the annual catalyst cost in the first two to three weeks of the contract. Quotes in CHF, EUR or USD, ex-works Lausanne.
What does a pilot cost?
A Field Trial is scoped around one vehicle, one vessel, or one genset — up to roughly 250,000 L of treated fuel over six weeks. We quote after the technical call once the fuel type, volume and measurement protocol are confirmed.
What about CO₂ reporting / ESG?
Each Operational Programme and Strategic Supply contract includes a quarterly report with litres saved, CO₂ avoided, and emissions delta (NOx, CO, HC, PM) — formatted for direct integration into your ESG / CSRD reporting.
Where is NTROPYX produced?
Engineered and produced in Switzerland since 2014 by Virgo Global Energy SA. European and international supply are routed from Lausanne. Swiss Made on the product label.
