Four fluids, one standard of proof

Every batch leaves the plant with its certificate of analysis. Nothing ships on a promise.

AdBlue® By Madin

Urea 32.5% and deionised water to ISO 22241 and DIN 70070, for SCR on Euro 4, 5 and 6 diesel engines. Cans of 10L and 20L, 200L drums, 1000L IBCs and forecourt pumps.

AdBlue® data

MADIN COOLANT

OAT antifreeze graded by MEG content, free of amines, borates, nitrites and nitrates. Tested to ASTM D-3306 and D-6210, from −5°C to −37°C, plus a low-conductivity EV grade.

AUS 40

Urea 40% to ISO 18611 for marine SCR under IMO MARPOL Tier III. The higher concentration cuts storage volume by roughly 20% against AUS 32. IBC 1000L, or pumped aboard at the berth.

Marine supply

MADIN CLEANER

A dedicated flush for SCR, DPF and EGR: dissolves carbon soot and urea crystals, lowers back-pressure, and leaves catalyst activity untouched. Diluted 1:10 with clean water.

How it works

NOₓ leaves the pipe as nitrogen and water

AdBlue® is injected into the exhaust after the engine and before the catalyst. Heat breaks it into ammonia and carbon dioxide. Inside the catalyst the ammonia converts nitrogen oxides into nitrogen and water vapour — the same nitrogen that makes up 80% of the air we breathe.

Urea 32.5%

The rest is deionised water. Purity is what an SCR injector depends on: technical-grade urea at ISO 22241 purity, blended with EDI ultra-pure water.

85–95% of NOₓ converted

SCR removes up to 90% of NOₓ, 50–90% of HC and CO, and 30–50% of particulates. Fleets running SCR rather than EGR report fuel consumption 3–5% lower.

A known working window

The fluid crystallises at −11°C and decomposes to ammonia above 80°C. Keep it sealed at 15–30°C out of direct sunlight. The recommended shelf life is one year from manufacture; the detail follows the storage temperature, within the ISO 22241 framework.

Every batch tested, every certificate published

SGS Vietnam measures the ISO 22241-1 parameters for AUS 32 on each production batch, and the report is published rather than filed. Report 26073103F3 covers batch 08/2026, issued 31 July 2026.

  • Urea content, density, refractive index, alkalinity, biuret, aldehydes and insolubles
  • Trace metals — phosphate, calcium, iron, magnesium, sodium, potassium
  • A reference sample retained for every lot, so a result can be re-checked later
  • Two codes on every label identify the exact batch a delivery came from

Beyond the bottle

What a fluid supplier owes its customers

Four things a purchase depends on, each with a page of its own rather than a promise on this one.

Service and rescue

SCR and DPF maintenance at Madin service points and on site, flushing with MADIN CLEANER, and a 24/7 hotline for delivery and on-site rescue.

OEM and private label

Production under your brand from Vietnam’s first VDA-certified plant, with the labelling dossier and an EAN-13 per SKU.

Where to buy

More than 800 points of sale and 1,700 points of use, at rest stops and filling stations along the routes fleets actually run.

The paperwork

Data sheets, safety sheets, certificates, and an SGS report for every production batch.
