Quality, checked at every stage

From the urea that arrives to the pack that leaves, our on-site QA/QC laboratory tests every batch against ISO 22241.

01In the lab

Eight parameters, and why each one matters

Each tells us something different about whether the fluid will do its job in your SCR system.

01Urea concentration: The active ingredient. Too little and NOx isn't fully treated; too much and it can crystallise.
02Density at 20 °C: A quick, dependable cross-check that the concentration is right.
03Refractive index: A second, precise measure of how much urea is dissolved.
04Alkalinity (as NH₃): Shows whether any urea has started to break down into ammonia.
05Biuret content: A by-product of urea that can leave deposits in the SCR system.
06Aldehyde content: Traces left over from urea manufacture, which must stay very low.
07Insoluble matter: Solid particles that could block filters and dosing injectors.
08Phosphate content: Harms the SCR catalyst, so it's held to the smallest trace.

02Seven stages

Quality isn't a final inspection. It's built in at each step, so problems are caught where they start.

01
Raw material inspection

Urea is checked for purity before it's accepted.
02
Purified water production

RO and DM treatment of the water for every batch.
03
Precision mixing

Blended to 32.5% on automated lines.
04
In-process testing

Samples checked while the batch is being made.
05
Final product testing

The finished batch against every ISO 22241 limit.
06
Batch approval & packaging

Only an approved batch goes to the filling lines.
07
Safe dispatch & delivery

Loaded with care and delivered across India.
