Diesel Exhaust Fluid (DEF)


Why does Beaudry Oil & Propane distribute TerraCair® as their DEF product?

TerraCair® is a Diesel Exhaust Fluid (DEF) known for its ultra pure handling and formulation process.  Today's engines have multiple DEF sensors that react negatively to DEF that is not pure in quality and specifications.  Go with the winner!- TerraCair® Ultra Pure DEF that guarantees the best and the purest DEF in the industry.

What is TerraCair®?

TerraCair®, AUS 32, is an API-certified, Diesel Exhaust Fluid (DEF) of technically pure urea mixed with demineralized water that is designed to meet the Specifications of DIN 70070:2005 and ISO 22241-1:2005 for NOx abatement technologies. TerraCair® is used in Selective Catalytic Reduction (SCR) systems to change the Oxides of Nitrogen (NOx) emissions in diesel exhaust to nitrogen and water vapor. Nitrogen makes up about 78% of the air we breathe every day.

What are the benefits of using TerraCair®?

Diesel engine vehicles equipped with SCR will have a separate tank to hold the DEF. Those vehicles using TerraCair® not only meet the 2010 tailpipe standard, they also deliver significant fuel economy. It’s good to know you’re cleaning the air while increasing your MPG.

Why choose TerraCair® over other brands?

TerraCair® is an API-certified, ultrapure, formaldehyde-free DEF that is a safe, environmentally friendly solution for SCR technology.  Terra Environmental Technologies (TET) manages the complete process from the gas fields to the vehicle tank.  TET is the only manufacturer who controls and oversees the entire distribution chain to ensure that the product quality delivered to the customer’s tank complies with ISO 22241.
