Lower fuel costswith measuredevidence
NEO-EXERGY is a fuel-oil conditioning filter system evaluated against your fuel, equipment and operating profile. Qualify the site, measure the baseline, verify the outcome—then decide whether to scale.

THE BUSINESS CASE
One operating cost Two decisions
Fuel is both a direct cost and a major source of operational CO₂. NEO-EXERGY projects start by testing whether the same measured reduction can improve cost per unit of output and estimated fuel-derived emissions—without asking you to trust a universal claim.
Protect uptime
Review fuel, tank, piping, load profile, safety and OEM conditions first.
Keep the evidence auditable
Separate fuel-derived CO₂ calculations from exhaust-gas concentration readings.
WHERE TO START
High-fuel-use assets with measurable output
The strongest first projects are stable-load applications where fuel input and useful output can be normalized before and after treatment.
01⌁
Industrial boilers
Factories, hotels, food, textile, paper, laundry, hot-water and thermal processes.
Heavy fuel oil diesel kerosene02⌁
Diesel generation
Remote sites, mines, islands, construction, hotels and backup or prime power.
Track g/kWh or L/kWh03◫
Marine & fishing
Vessels, auxiliary engines and shipboard generators with controlled test windows.
Correct for load and voyage conditions04▰
Heavy fleets
Trucks and construction equipment using matched vehicles or controlled duty cycles.
Pilot only after warranty reviewFROM INTEREST TO A DECISION
Before the next fuel invoice, answer one question: is this asset worth testing?
A persuasive proposal should reduce uncertainty, not hide it. NEO-EXERGY starts with a short commercial and technical screen, then earns the right to proceed with measured evidence.
Quantify the exposure
Monthly fuel use × delivered fuel price reveals the cost of leaving the question untested.
Set the proof standard
Agree the normalized KPI and decision threshold before equipment is installed.
Run a bounded pilot
Compare like-for-like operating periods. Scale only if the agreed evidence supports it.
No commitment. If the asset or available data does not support a credible pilot, we will say so.

A new market offer, backed by an established cross-border business network
NEO-EXERGY is presented by NANOBEST JAPAN, led by Representative Director Takashi Umeki. The company’s official pages document operating and distributor relationships in Thailand, Hong Kong / South China and Taiwan, alongside overseas photocatalyst projects.
✓Thailand operating company and university collaboration
✓Officially listed partners across Hong Kong / South China and Taiwan
✓Published photocatalyst work in Thailand and Taiwan
Why this matters to a NEO-EXERGY buyer
It provides corporate continuity, local relationship experience and a route for market support. It does not replace NEO-EXERGY-specific technical verification—which remains a separate requirement.
!Company credentials and photocatalyst references demonstrate NANOBEST JAPAN’s operating background. They are not evidence of NEO-EXERGY fuel-saving performance.

SOURCE-BASED EVIDENCE
What the published data says—and what it does not
These are source-case observations, not guaranteed outcomes. We show the test context and the limitations so buyers can design a better pilot.
Fuel-use reduction reported on days 1–6
South Africa NEO-100 Euro 3 diesel generator baseline 722.5 g; day 1 630 g, day 6 640 g.
Fuel-use reduction reported on day 8
The same source notes that re-conditioning was required after seven days—an important operating variable.
Two reported marine-generator tests
China Euro 5 fuel 2.5 L two-hour runs fuel circulated through the unit 15 times.
Manufacturer-reported B-heavy-oil case
The official website reports approximately 20% lower fuel cost and estimated CO₂; full test conditions are not published.

FOUR-GATE PILOT
A buying process designed to survive technical review
Site qualification
Fuel type, monthly volume, asset, load profile, tank and piping, local requirements.
Measurement plan
Agree the normalized KPI: L/t-steam, g/kWh, L/hour at fixed load, or L/100 km.
Controlled verification
Record baseline and treated runs under comparable conditions; retain raw data.
ROI and scale decision
Model site economics from verified reduction, operating cost, maintenance and installation scope.
YOUR NUMBERS
Build a scenario before spending capital
Use this calculator to set the commercial threshold for a pilot. We will replace assumptions with measured site data.
SCENARIO OUTPUT
Potential monthly saving—
Potential annual saving—
Simple payback—
Gross fuel-cost scenario only. Use the same fuel unit and currency throughout. Electricity, maintenance, replacement, tax and other operating costs are excluded. This is not a performance, savings or payback guarantee; verify it with a load-normalized operating test.

Questions a serious buyer should ask
Is a fixed saving guaranteed?＋
No. Published source cases report different outcomes by fuel, asset and time. Every proposal must state assumptions and verify the result at the site.
Which fuels and assets are in scope?＋
Official materials list A/B/C heavy fuel oil, diesel, kerosene and waste oil, with applications including boilers, generators, vessels, trucks and heavy equipment. Compatibility is still confirmed project by project.
Is NEO-100 the product name?＋
NEO-EXERGY is the current product family; NEO-100 is one model name used in the source material. Model selection and final specification require manufacturer confirmation.
Does exhaust CO₂ always decrease?＋
Not necessarily as a concentration reading. Published generator tests show CO₂ concentration increases in some treated runs. Total fuel-derived CO₂ must be calculated from normalized fuel use and useful output.
Can the system be installed anywhere?＋
No universal statement is appropriate. Piping, pressure, temperature, materials, safety, local approvals and equipment warranties must be reviewed.
