DEF Equipment: What You Need to Know

Diesel exhaust fluid (DEF) is a clear, colorless liquid that is used in diesel engines to reduce harmful emissions. DEF is injected into the exhaust stream of the engine, where it reacts with nitrogen oxides (NOx) to convert them into harmless water and nitrogen.

DEF is required in all diesel engines that are built after 2010 that are over 75 horsepower. This includes a wide variety of vehicles, including trucks, buses, construction equipment, and agricultural machinery.

There are a number of different DEF equipment options available on the market. Some of the most common types of DEF equipment include:

  • DEF tanks: DEF tanks are used to store DEF. They come in a variety of sizes, from small portable tanks that can be mounted on a vehicle to large stationary tanks that can be installed at a fleet depot.
  • DEF pumps: DEF pumps are used to transfer DEF from the tank to the engine. They come in a variety of power options, including electric, gasoline, and diesel.
  • DEF meters: DEF meters are used to measure the amount of DEF that is being dispensed. They are typically used in conjunction with a DEF pump.
  • DEF nozzles: DEF nozzles are used to dispense DEF into the engine. They come in a variety of sizes and configurations.

When choosing DEF equipment, it is important to consider the size of your fleet, the type of equipment you use, and your budget. You will also need to make sure that the equipment you choose meets the emissions standards for your area. Most importantly, only quality equipment should be used.

Here are some tips for maintaining your DEF equipment:

  • Keep the DEF tank clean and full. A dirty or empty DEF tank can damage the engine.
  • Change the DEF filter regularly. The DEF filter should be changed according to the manufacturer’s recommendations. This will help to ensure that the DEF is clean and free of contaminants before it is injected into the engine.
  • Inspect the DEF lines and connections regularly. Make sure that the lines are not leaking or damaged. If they are, they should be repaired or replaced immediately.
  • Store DEF in a cool, dry place. DEF should be stored in temperatures between 10 and 32 degrees Fahrenheit. Storing DEF in hot temperatures can cause it to degrade.

By following these tips, you can help to ensure that your DEF equipment is working properly and that your engine is emissions compliant.

Benefits of using DEF equipment

There are a number of benefits to using DEF equipment. These include:

  • Reduced emissions: DEF helps to reduce harmful emissions from diesel engines, which can help to improve air quality.
  • Increased fuel efficiency: DEF can help to improve fuel efficiency by up to 5%.
  • Longer engine life: DEF can help to extend the life of your engine by reducing wear and tear.
  • Lower maintenance costs: DEF can help to lower maintenance costs by reducing the need for repairs and replacements.

If you own or operate a diesel engine vehicle, then DEF equipment is a worthwhile investment. It can help to improve air quality, save fuel, and extend the life of your engine. Reach out to our sales team at for help in finding the best DEF storage and dispensing equipment for your every need!
