Arla 32 (Petrobras Flua)

ARLA 32 (Automotive Liquid Reducing Agent) is a chemical that acts to reduce the nitrogen oxide (NOx) released by vehicular exhaust gases. Reacting with these gases, ARLA 32 turns NOx into water vapor and nitrogen, gases that are harmless to human health. ARLA 32 allows the Euro V emissions standard - for engines fitted with the SCR technology (Selective Catalytic Reduction) -, to be met.

To ensure product quality all the way to the end consumer, we have rolled-out Petrobras Flua on the market. This is the only ARLA 32 with Petrobras brand's quality assurance. It is certified by INMETRO and meets international quality requirements set forth under ISO 22241.


ARLA, a product based on high purity urea, captures much of the nitrogen oxide released by the engine's combustion before the pollutant gas gets released into the atmosphere.

This product is designed for diesel-fired vehicles produced with the new SCR (Selective Catalyst Reduction) technology.
