EcoSmart +Blue is the AUS 32 manufacturing operation of Aum SLN Enterprises. The plant is commissioned and producing Diesel Exhaust Fluid from GNFC technical-grade urea and deionised water, blended to the concentration window specified by ISO 22241-1 and IS 17042 (Part 1).
Bulk ships direct from the plant - 200 L barrels, 1000 L IBCs, and tankers. Smaller volumes reach customers through our franchise partners, who sell under the EcoSmart +Blue brand.
DEF quality is uneven in the market. Three things drift more than anything else, and each of them costs the engine. We hold all three on every batch that leaves the plant.
Urea concentration
What drifts in the market
DEF in the market can drift outside the required concentration window. Either way, the SCR system can't convert NOx properly and may throw fault codes.
What we do
Every batch is verified on a refractometer before release. If the reading falls outside the specified window, the batch doesn't ship.
Urea grade
What drifts in the market
Cheaper agriculture-grade urea sometimes gets blended in. It carries impurities that crystallise inside the SCR catalyst and shorten its life.
What we do
Government-approved technical-grade urea only. Same supplier, same grade, on every batch - no blending with cheaper substitutes.
Water content
What drifts in the market
Adding water to stretch volume produces fluid that looks the part but starves the SCR system of urea - so the engine pays the cost on efficiency and emissions.
What we do
Blended with deionised water and checked before release. The recipe doesn't move to chase margins.
Every EcoSmart +Blue franchise receives the identical fluid from the same Chikballapur line. No territory-specific blends, no different quality tiers.
Built to ISO 22241-1 - the same specification used by OEM-supplied DEF brands across India. The fluid that goes into a Tata, BharatBenz, or Gulf-fuelled vehicle is built to the same standard as ours.
DEF that meets spec keeps the SCR catalyst clean and lets the engine run at the efficiency it was designed for. Off-spec fluid quietly compromises both.
200 L barrels, 1000 L IBCs, and tankers ship in bulk from Chikballapur to franchise depots and businesses. The 5 / 10 / 20 L formats reach customers through our franchise partners, sold under the EcoSmart +Blue brand.
Customised tanker volumes for franchise depots and large fleet operators on scheduled replenishment.

DEF only works in SCR systems if the chemistry holds - concentration in range, no contamination. Two simple checks run on every batch before it leaves the plant.
International and Indian standards for AUS 32 - composition, handling, transport, and storage all controlled to spec.
Every batch is verified before release. If the concentration reading sits outside the window below, it doesn't ship.
A reagent kit confirms purity at dispatch - turns blue on on-spec product, pink on contaminated or off-spec product.
An RO + EDI purification tower produces the deionised water for every batch - mineral contamination is controlled at the source.
