Diesel Exhaust Fluid from TAC Energy

What is Diesel Exhaust Fluid?

Diesel Exhaust Fluid (DEF) is a non-hazardous product that consists of 67.5% de-ionized water and 32.5% urea. It is not a fuel additive and cannot be combined with diesel fuel, but rather is contained  in a dedicated tank for diesel engines and injected into the exhaust system using a Selective Catalytic Reduction (SCR) system.

Is Diesel Exhaust Fluid A Requirement?

The EPA is changing emissions standards for NOx emissions, particulate matter and other pollutants from diesel engines. DEF is used in the emissions systems on new diesel powered equipment to meet these standards.

How Does It Work?

When DEF is injected into the exhaust using a SCR system, it combines with a catalyst to break down NOx into nitrogen and water. In addition to reducing emissions, the added benefits of this system are increased fuel efficienty and longer oil change intervals.

Does My Equipment Require Diesel Exhaust Fluid?

Diesel powered vehicles and heavy equipment manufactured before 2009 do not require DEF or any retrofit. The chart below shows the scheduled implementation of diesel powered equipment requiring DEF.

 2009 Tier 2 Light Duty Trucks
 2010 Heavy Duty Highway Trucks & Buses
 2014 Non-Road Diesels
 2015 Fuel Based Ocean Going Vessels
 2016 SCR Catalyst Based Ocean Going Vessels
 2017 Locomotive and Marine

How Much Diesel Exhaust Fluid Will I Use?

Consumption is measured by a “dosing rate”. Data from manufactures and field reports from actual users show usage at 2% – 3% of diesel fuel consumption.

Is all Diesel Exhaust Fluid the Same?

No. Contaminated diesel exhaust fluid can quickly ruin your SCR system and void your warranty; shutting your equipment down and costing tens of thousands of dollars in repairs and downtime. That’s why TAC Energy is meeting the international performance and  stringent quality standards that engine manufacturer service warranties specify must be used.
