FALSE. There are many misconceptions about DEF in certain sectors, which brings us to the first assertion in this post: DEF is DEF regardless of the brand. Commercially, Diesel Exhaust Fluid is the same substance with the same ingredients since it is subject to a national regulation with the intention of protecting consumers. Specifically, bottled DEF brands must have the API certification printed in the label. This, in addition to being an indicator of quality, also requires manufacturers to put a batch number on said labels. Finally, the manufacturer must keep a physical sample of that batch, in order to identify any subsequent defects; there is an actual record of test tubes, and in the case of Noxguard, it can even be consulted by any buyer on our page.

DEF is DEF regardless of the brand


It´s not uncommon for CSR technology and indicators to fail, this is a reality that occurs more often than poor quality of DEF; of course, DEF must be adequately handled, avoiding contamination once acquired. There have been reports of consumers mixing DEF with diesel, which is a huge mistake, but some think: “it must be the poor quality of the product”. In any case, manufacturers provide a guarantee policy: a physical sample of the corresponding batch is compared with the DEF contained in the unit with a diesel engine. If there is a difference, contamination probably happened due to a bad handling of the product or adverse conditions when it was supplied and/or dispatched. Please visit our blog, where you´ll find interesting stories that reflect on this final user problem.

Noxguard Diesel Exhaust Fluid and some interesting facts

We would like to share some interesting facts regarding Noxguard Diesel Exhaust Fluid and it’s performance inside the Selective Catalytic Reduction (SCR) system of a diesel engine.
First of all, the difference between the combustion process of a gasoline engine and a diesel engine are significant. Diesel engines, in order to combust, require high pressure (no spark plugs) and lots of air, about 65 parts of air for every part of diesel; meanwhile gasoline engines use 14 parts of air per 1 part of gasoline. Thus the reason for NOX emissions to be higher in diesel. Also gasoline engines operate at lower temperatures than diesel engines.
And now, the magic of the chemistry of our Noxguard DEF inside the SCR System step by step:



Noxguard Disesl Exhaust Fluid Chemistry Facts



  • Combustion is performed in the engine, and emissions are released.
  • In the SCR system, Noxgard DEF is sprayed to the fumes and the chemical magic begins.
  • With the high heat of combustion, the DEF converts to ammonium.
  • Ammonium is mixed with the NOX of the fumes, and there is water vapor present too.
  • The result of this mixture produces Nitrogen (which we find naturally in the air we breathe).
  • And on the other side we obtain water, yes water.



The Chemistry looks like this:


  • Ammonium which are 3 atoms of Hydrogen plus one of Nitrogen (4NH3).
  • Plus NOX which is 1 atom of Nitrogen plus 2 atoms of Oxygen (2NO2).
  • Adding in Oxygen (O2).
  • Results in Nitrogen (N) plus Water molecules (H2O).




Yes, of course, you need the specially designed SCR system that has all the dosage technology and the filtration process to accomplish the job.

2017 Diesel Exhaust Fluid Forecast (part 1)

Having a better understanding of the DEF Industry and the internal and external factors that influence its pricing could assist you in making key decisions in your company. That is why in this blog titled 2017 Diesel Exhaust Fluid Forecast, I will outline some of these factors and general information in hopes that this information is useful for our readers. We will discuss topics such as DEF pricing, the DEF industry evolution, new DEF equipment solutions, other emission controlling technology and finally  DEF usage in North America.



Diesel Exhaust Fluid forecast

DEF Price

In this first part of the 2017 Diesel Exhaust Fluid Forecast, we will discuss DEF prices. Diesel Exhaust Fluid is composed of 32.5% urea and 67.5% DI Water. Urea is a commodity that is mainly used in the world as a fertilizer and is traded internationally as a commodity. In the case of DEF, we utilize an automotive grade Urea that is more a specialty than fertilizer urea but also is considered a commodity. Fertilizer Urea prices fluctuate based on the fertilizing seasons. In most countries of the northern hemisphere most crops are prepared and planted at the beginning of the year, thus, Urea is usually at a higher price then. When most of the crops are harvested and during the winter season, then the use of Urea drops and so does the price.

*Prices of automotive grade urea began low in 2016, therefore lowering the price of DEF. A brief rise in prices lasted only a couple of months. By the end of summer 2016, it plummeted to the lowest price ever seen since 2007. Fast forward to February 2017, prices of urea are a bit higher than the same time last year. We are already seeing a greater demand for DEF this year compared to last year. Add to this that fertilizer Urea is also rising, then DEF prices should follow. The tendency is on the upside.

Transliquid Technologies follows the DEF market very closely and adjusts its pricing up or down monthly. We do this in order to give our customers the leading edge when it comes to being competitive.

What is interesting for us, is the fact that even though the market of DEF varies monthly we continue to see the prices at the pump fairly stable and high. The large truck stop chains justify these high prices on the fact that they make large capital investments to provide DEF at the pump, but I want to throw this question out there, how long is this supposed to last? The price differential from our distributors to the pump pricing is significantly higher even though it is a commodity.




Noxguard Diesel Exhaust Fluid Mexico

Noxguard_DieselExhaustFluid_MexicoIf you follow us on social media or on our TransliquidTV page, you would have seen one of our posts about the new operations of Noxguard Diesel Exhaust Fluid Mexico. It follows the original strategy to have Noxguard in the neighboring country and to continue further south. This project has been in the works for more than a year. It wasn’t until this year that all the pieces aligned and it moved forward.



The new plant is located adjacent to the PeroxyChem facility in Ecatepec de Morelos. The new facility provides customers a very convenient location in central Mexico sourcing Diesel Exhaust Fluid in bulk quantities. Just like the U.S operations, the plant in Mexico will follow all the same procedures and batch tracking formats. Customers can track their batches, and benefit from all parts of the Quality Assurance Program including our own private fleet of dedicated Noxguard trailers.

The Future

Noxguard Mexico has already started moving product in the capital to key transportation clients. We have the capability of covering the entire country, and will be moving aggressively towards all the major cities.  As a result of our customers continuing to require DEF. The market continues to ask for Noxguard Diesel Exhaust Fluid. Our customers in Mexico value the quality in addition to the dependability that comes with the Noxguard brand.  In conclusion, Noxguard is bringing a complete package of manufacturing expertise and technology which was lacking in Mexico.

What to do if the DEF tank gets contaminated

What to do when the DEF tank gets contaminated?

We couldn’t stress more on the fact that Diesel Exhaust Fluid has to be handled with specific equipment to avoid contamination, and therefore avoid damage to the SCR system that would be very costly. So you have all the equipment necessary and you are doing everything right, until someone accidentally mixes the Diesel Exhaust Fluid with another fluid. Although everything was going right, there is always a chance for human error. Depending on the size of the container, here is what you can do.

2.5 gallon bottles: Simply dispose it. There is no way to clean out the container after the Diesel Exhaust Fluid has been contaminated without compromising the integrity of any remaining product.

55 gallon drums: Just like the bottles, the product should be disposed. There is no way to clean out the drum after the Diesel Exhaust Fluid has been contaminated without compromising the integrity of any remaining product. Drums are the easiest to get contaminated, simply because anyone can open and close them. Drums are one way systems, and should be thrown out after each use. These are recyclable and preferred by small operations.

275 & 330 gallon totes : Although not as easy as the smaller packaged containers, you must dispose of the DEF if it becomes contaminated. We do not recommend cleaning out the container after the Diesel Exhaust Fluid has been contaminated, improper cleaning could compromise the integrity of any new product that can be stored.  We recommend contacting your local environmental waste disposal company for a nearby disposal site, they can advise were and how this can be done.Totes are meant to be temporary bulk containers, and can be reused, as long as there is a closed loop system and they are dedicated to DEF. A brand new tote, with a closed loop system, refilled only with DEF should never have contamination issues as long as the seal is intact.

Follow the link for the Waste Management Industrial and Hazardous Solutions page :

DEF Tank gets contaminated

Above ground storage tanks & Underground storage tanks: We see this happening in places were there are multiple products being sold. The delivery driver can make a mistakes and off-load in the wrong tank. So not only is the DEF tank contaminated, but there is a high possibility that by the time the clerk figures out what happened, their customers have already filled up with the contaminated product. On a case like this it is important to give us a call so we can asses the damages. We would work on a case by case basis , to determine a plan of action. It is important to know that DEF contamination is considered an emergency and we would need to start working on a remediation plan immediately.

A cleaning crew would be sent out to the tank location as soon as possible. All the liquid would have to be disposed of, whether it is a mix of DEF and another product or even if it is just the other product. After properly cleaning the tank, a new load of DEF would be loaded, and a full lab test completed to make sure there is no contamination. Depending on the size of the tank, this process could take anywhere from 1-3 days to complete.

Purity down the line:

As the manufacturers we recommend to our customers to use the correct DEF equipment in order to keep the product clean down the line of distribution. We work with dedicated tankers to deliver our bulk product and avoid any cross contamination from the transportation of the DEF. For the smaller distributors we sell one way drums that should not be reused, as well as the bottles and totes. Totes come with a closed loop system, and can be refilled as long as the seal is intact. We recommend all our distributors buy totes from us, and discourage buying used totes, saving a couple pennies could cost thousands in damages in the long run.

Do not pee in your DEF tank, read why here!

We have been hearing over and over a comment about Diesel Exhaust Fluid that is particularly frightening ,

“Diesel Exhaust fluid is the same as ____ urine”           brown_cow_197654

Fill in the blank with any animal you can think of, we have heard it all but most recently , bat and cow urine. We have also heard of people thinking that urinating in their DEF tank will make the engine run. So the common misconception people have about Diesel Exhaust Fluid is that it is made from urine. This is NOT true, and acting upon this idea could cost you thousands of dollars in repairs to your SCR engine. On this blog, some light will be shed on the subject, and we will finally debunk this myth for good.

Those who believe in this myth used deductive reasoning to get to that conclusion , so according to them:

Urine = Urea

Urea+water= Diesel Exhaust Fluid

therefore Urine+ water= Diesel Exhaust Fluid


Urea Urea is an organic chemical compound, or the waste produced by the body after metabolizing protein. But since 1828, German scientist Friedrich Wöhler invented the process to create the synthetic version of urea. In 1870 the process of producing  urea through dehydrating ammonium carbamate under conditions of high heat and pressure was invented. So yes, urea can be obtained from urine, but lets find out why Diesel Exhaust Fluid is not just urine and water.

I will be comparing the material data sheets of  both automotive grade urea vs human urine.

  • According to wikipedia, “Human urine is an aqueous solution of greater than 95% water, with the remaining constituents, in order of decreasing concentration urea 9.3 grams/L, chloride 1.87 grams/L, sodium 1.17 grams/L, potassium 0.750 grams/L, creatinine 0.670 grams/L and other dissolved ions, inorganic and organic compounds.” Read the full description here.
  • Diesel Exhaust Fluid uses automotive grade urea, at 32.5% concentration. This urea contains , 0.3% Biuret maximum, 0.5 % magnesium max , 0.5 % calcium max, 0.5% phosphate max, 0.5% iron max,0.5% potassium maximum.

When comparing the two there are various differences:

  1. Human urine only contains 9.3 grams per liter of urea concentration
  2. Human urine also contains chloride, sodium , potassium , creatinine and other dissolved ions
  3. Human urine is 95% water, which is also full of ions and minerals

The water needed to create Diesel Exhaust Fluid has to be de-ionized and de-mineralized , a process that only a highly specialized filtration machine can achieve.


From all this information we can conclude that even though urine has urea, it is not the correct concentration nor does it have the purity needed. The water that comes from urine is also full of ions and minerals which make it very low quality water.


Diesel Exhaust Fluid is highly concentrated and very pure urea plus de-ionized water .The standards for Diesel Exhaust Fluid are very specific and can be found here

I hope that this blog has been informative, highlighting the differences between urine and Diesel Exhaust Fluid. Please do not urinate in your DEF tank, the SCR system will be damaged and it will cost thousands of dollars to repair.

Here at Transliquid Technologies we specialize in providing the best quality of Diesel Exhaust Fluid.

SCR sensors for Adblue/Diesel Exhaust Fluid – guest blogger

We are happy to kick off our guest blogger series, something that has been on our radar for sometime.  We feel it is important to shine the light on our industry friends where benefits may be of value to you.


emty icon & button; blue and glass

In the spirt of blogging, loving to share content; we are opening our blog here at Transliquid Technologies to guest bloggers. We are happy to shine the light on our friends at Gentech, a UK based company focusing on SCR sensors in Europe for the AdBlue/DEF market.  What is interesting and unique about Gentech is their innovation and approach at an emerging market.

Ms. O’Rorke contacted us a little while back and we began the conversation on their new products for the AdBlue European market.  Ms. O’Rorke handles Public Relations and was graceful enough to engage in a Q/A session with us here at Transliquid.


Transliquid – Thank you for joining us, first of all.  It’s good to have you on our blog.

Gentech-  Thank you, this is a great concept.

Transliquid– Can you explain to us all, what these SCR sensors are?

Gentech-  The sensors are aimed at detecting the presence of and measuring the level and temperature of, AdBlue – known as a Diesel Emission Fluid (DEF) in North America -the exhaust after-treatment method used with diesel engines to reduce NOx. emissions.

Transliquid –  Where are these sensors fitted?

Gentech- Well, that is where we shine.  These sensors are for the actual AdBlue/DEF tanks on buses and trucks.  We partner with original equipment manufacturers and component suppliers to design and deliver these unique solutions. Later this year we will be launching a combined temperature/level and quality SCR sensor for retrofitting. I’ll let you know when that is ready.

Transliquid –  I understand that you have also managed to included heating elements into Adblue/DEF tanks.  Can you expand on this a bit?

Gentech-  Yes, we have added an option for a heating element in case of AdBlue/DEF freezing in cold environments, plus we can furnish an 80 or 100 micron filter on the suction line to prevent unwanted particles being fed into the SCR system.  This also comes with incorporated compact connector for quick assembly to the wiring harness.

Transliquid – So let’s have a look at these sensors.

Truck & Bus dv2.indd






Transliquid-  Let’s talk about the integrity and quality of AdBlue/DEF.

Gentech- I am glad you brought this up because our customers have pushed to create the following.  We have an optional integrated quality sensor detects when non-DEF/AdBlue fluids are added to the tank. This sensor is a solid state electronic device that works by detecting differences in the properties of the medium in the Adblue tank. The device will alert when filling with Adblue/DEF tank with unauthorised liquid (leading to out of specification exhaust emissions) as well as aiding in the prevention of damage to SCR system components.

Transliquid- Ok so looking at the pictures brings me to my next question, how do secure/fit these sensors for the Adblue/DEF tank?

Gentech– We often work in conjuction with tank manufacturers to facilitate the engineering of suitable systems and cut costs in the long run. Bayonet and flange fit mounting of the sensor assembly into the tank is most common, but we have rubber seal options which can simplify tank designs.








Transliquid- Very good. Last, I got the opportunity to read your case study with one of the largest bus fleet manufacturers.  I’ll let you expand on that.

Gentech- Yes we worked together with this manufacturer at developing a solution to measure level and temperature for their buses.  The AdBlue/DEF liquid had to be at -37 after motor has been running for 20 minutes.  What we did was a creation of a level sensor that operated down to a minimum of 8% tank capacity, this was to ensure that the dosing system never ran empty.  The temperature sensor was capable to operate in the range of -40 & +70 with a 80 micron filter.  Last, we included a heating tube that was connected to the vehicle’s heating and colling system.  What we came up was a level sensor based on zero maintenance, robust plastic and stainless steel construction, with a super easy quarter turn fitting.



I’d like to take the opportunity to thank Mr. Imogen for the content and pictures used on this blog post. It truly been a pleasure to highlight Gentech, a leader in liquid level sensors, position sensors, flow switches, and optical sensors.

As always, we alway love to hear your comments so sound off your initial comments.  Would you like to see this technology up and close here in the US?

If you are interested in being our next guest blogger, feel free to contact us. 

Thank you for reading our Blog.

Diesel Exhaust Fluid Mini Bulk Fleet dispensers Texas – hot enough?

Folks – its been a very exciting first quarter for us and our DEF distributors. I do want to take the time to welcome our new subscribers and hope you will find our blog informative, fun and valuable to you and your customers.

brand_loyaltysmallWe have been involved in a lot of exciting online discussions all centering around Diesel Exhaust Fluid (DEF). Topics range from difference in all the merging brands, regional pricing, and of course equipment. I do want to get back to the topic of DEF branding on a separate blog entry because it was very interesting to hear and discuss the perception of branding. That should be very interesting topic here, don’t you all think?

Anyway, back to topic. The question that keeps coming back lately for us here in the South is about temperature and how it impacts Diesel Exhaust Fluid. We are now, let’s see in the middle of April, and today was 89F already. So, the question begs, what do you do to help keep that temperature down for those of you already in amino bulk set up or considering it?

For those of you just starting to research Mini Bulk fleet dispensers for Diesel Exhaust Fluid (DEF ), we will define what a Mini Bulk tank is: Transliquid defines IBC totes as intermediate bulk containers (275-330 gal for DEF) , DEF Mini Bulk range starts at 400 gallons of DEF up to 2000 gallons, and Bulk in upwards of the last benchmark.

Now to be fair, there are a lot of great products out there, so we are not going to get into who is better, we always say do your homework and search for that product that meets your specific need. Now, to the question about temperature; below is a cut away from our friends at KleerBlue along with a temperature test, illustrating this topic.



400 gallon Mini Bulk Fleet



Our recommendation for any one searching for information or ready to move up to a Mini Bulk set up but still concerned about temperature. Take these questions into consideration:

1. Are the tanks single, double, or triple walled?

2. What is the insulating factor?

3. Are the tanks under a roof or open to the sun?

4.What is the power requirement?

5. Do you offer installation services?

6. Any leaching problems from construction materials?

7. Any corrosion problems?

8. Standard Warranty?

9. Is your DEF supplier ready to stand behind their product?

10. This is an obvious one, but make sure that the all wetted parts meet ISO 22241-3:2008(E).

10.5 Know the shelf like of DEF? If unfamiliar, give us a shout.


KleerBlue and Transliquid always recommends shading the insulating tank and dispenser, and turning over your fluid as much as possible to keep your DEF solution at its optimum quality.

Don’t forget to download the free temperature test document, so head over here now. Hopefully that will put your concerns at rest.


Thank you for reading our Blog.
