Live ISO 4406 · stored diesel fuel
Know your diesel is clean — in real time, anywhere on earth.
Trendfuel streams live ISO 4406 cleanliness data from your stored diesel, so you can see its exact condition in real time — while single-pass filtration from our strategic partner DieselPure brings it back into spec — even in the most remote and harsh environments on earth.

The problem
Stored diesel gets dirty — and dirty fuel is the silent killer of expensive engines.
Water, dust and degradation push stored fuel past ISO 4406 limits long before anyone notices. By the time an injector pump fails or a generator won't start on demand, the damage is done. Tank-level gauges can't see it. Periodic lab samples are already out of date.
Continuous, not periodic
Laser particle counters stream ISO 4406 codes from 4–70 µm to a secure cloud dashboard in under three seconds — not a lab report from last month.
ISO 4406 monitoring →Single-pass filtration by DieselPure
Our strategic partner DieselPure cleans the fuel with single-pass SAE J1488:2010 high-performance filtration — below ISO 4406 limits in one pass, at 40–2000+ L/min. Trendfuel monitors and integrates it.
How it works →Alarms & lockout
Instant email and SMS alerts on warning and limit thresholds, with optional dispensing lockout to stop contaminated fuel reaching the engine.
The technology →Built for your operation
One platform, three critical-fuel problems.
Standby fuel you can verify
Backup diesel must run the moment the grid fails. Continuous ISO 4406 data from Trendfuel shows its condition; single-pass filtration from DieselPure can bring it back into spec.
Data center solution →Protect haul-truck fleets
Remote sites, abrasive dust, huge fuel volumes. Live cleanliness data and high-flow filtration keep equipment productive and injectors alive.
Mining solution →Data for standby readiness
Hospitals, telecom and utilities can't gamble on stored-fuel quality. Trendfuel measures and reports it live, with the alarms and records to prove its condition; DieselPure can bring it into spec.
