The sceptic questions procurement asks first.

Every serious buyer opens with the same list. Direct, non-marketing answers written for technical, insurance and procurement teams.

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.

NTROPYX is formulated to meet the fuel specifications recognised by major engine manufacturers. We supply an SDS, a technical datasheet and the dosing documentation so your OEM and insurance teams can review. Operators using NTROPYX supply have not experienced warranty issues; we cooperate directly with OEM technical departments where relevant.

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.

At point-of-fill, into the bunker barge, the road tanker or the on-site storage tank. No injector hardware, no engine re-mapping. Deployment dosing is supervised by our technical team; operational dosing is automated or manual, depending on the site.

Engine bench and emission laboratory 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.

Per supply contract, 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.

Commercial supply is quoted after qualification, based on annual volume, fuel type, sector, delivery geography and documentation requirements.

Each operational 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.

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.
