New Diesel Exhaust Fluid Nozzle Makes Dispensing More Economical


Husky Corporation Unveils the X DEF Nozzle for Retail and Commercial Customers

PACIFIC, MO – Husky Corporation has introduced a new version of its highly successful “X” family of nozzles for safe and economical dispensing of Diesel Exhaust Fluid (DEF). The X DEF Nozzle contains all of the model’s standard functionality and features, coupled with components compatible with dispensing urea-based DEF, which can be corrosive to aluminum and other materials.
 
 
The X DEF Nozzle contains 100 percent ISO-recognized DEF-compatible components including Stainless Steel spout, polymers and O-ring materials.  The nozzle contains an automatic shut-off feature, Husky’s Streamshaper® to reduce splash back, a three-notch hold open clip lever, and a plastic handguard design. Even with those features the X DEF is lighter and less expensive than comparable DEF nozzles.
 
 
“Many DEF nozzles can be quite expensive because of the materials required to handle it. But we have found a way to bridge the gap with a fully functional version of Husky’s most popular nozzle that reduces the cost to dispense DEF,” said Husky Corporation Product Engineer Roger Wiersma.
 
The Husky X DEF nozzle is made with UL recognized components. It is offered with three-quarter NPT or BSPP thread. It is ideal for retail outlets and commercial customers including vehicle dealerships, repair shops, oil change facilities, fleet-service centers and other locations that regularly dispense DEF from bulk tanks or above ground storage systems.
 
To learn more about the X DEF Nozzle and all the other Husky Corporation Diesel Exhaust Fluid dispensing products call the company toll-free 800-325-3558.

On Site Environmental Chamber Takes Product Testing to a New Level

Husky Corporation recently installed a state-of-the art environmental chamber at its production headquarters in Pacific, Missouri. Nozzles, swivels and other fueling products can be subjected to extreme temperatures, ranging from +185 degrees to -85 Fahrenheit, in an effort to make sure the products are constantly improving.

This short video shows how it works.


 
Engineers wanted to replicate, and even surpass, the conditions safety regulators put in place when they test products. To learn more about Husky Corporation's quality processes, contact the company directly at 800-325-3558 or husky.com

New Resources Available to Prevent Misfueling in General Aviation

The consequences of placing the incorrect grade or type of fuel in an aircraft are very serious. This situation is referred to as "misfueling". In General Aviation (GA), where the majority of aircraft are fueled over-the-wing, there is a significant risk of misfueling which can lead to vapor lock, ignition failure or total engine failure. However, following proper safety measures will prevent potential disaster. 

The National Air Transportation Association (NATA) has launched the "Safety 1st Misfueling Prevention Program: Awareness Training for Line Service Professionals, FBO Managers, Customer Service Representatives and Pilots".  

http://nata.aero/Education-and-Training/Misfueling-Prevention-Program.aspx 


The program includes short videos that provide education about simple steps that can be taken to prevent misfuelings. A quiz follows the video presentation, after which individuals who pass can print a certificate of completion. NATA says the program is not intended to be a comprehensive training program, which must be completed before individuals attempt to fuel an aircraft. But it covers essential elements that serve as a good primer for those in each outlined job category.

The “Big Three”

NATA focuses on what it calls the Big Three items required to get the right fuel into aircraft every time: Proper fuel orders, the use of selective spouts, and grade verification.  

Let's take a moment to focus on spouts. Industry standards and best practices require that selective spouts be installed on all aviation overwing nozzles, which in essence are designed to prevent jet fuel from being inadvertently put into aircraft requiring Avgas.  

The Jet A Wide Oval Spout, also known as duckbill or J-Spout, is designed so it cannot be placed into most fuel openings for Avgas powered aircraft. However, some Avgas aircraft may not have restricted size filler ports. Other exceptions potentially include helicopters.  So the selective spouts only provide a layer of protection against misfueling; they are not fail-safe. It is up to the ground fuel handler to make sure they have covered the big three fueling checks before dispensing the fuel into the aircraft.  There are no exceptions to these checks. 

One interesting point of the NATA online presentation is that if you want to use jet fuel, but need to use a round spout, the round spout can only be used temporarily. And it must be immediately removed after use.  This is a very important practice to prevent any mistakes during the next refueling.

Additional Safety Practices

One additional layer of protection that is found in the field for Aviation nozzles is the use of colored nozzle handles. Black handles are in place for nozzles using Jet fuel. Red handles depict nozzles that dispense Avgas. Hewitt always asks customers about the type of fuel to be dispensed and the handle-color required before orders for nozzles are entered.   

An additional resource with detailed information on preventing misfuelings is NATA Safety 1st eToolKit which is available at the following link.

Why Handling and Dispensing Diesel Exhaust Fluid Requires Special Components

Diesel Exhaust Fluid (DEF) is a fairly simple and non-hazardous solution that is making a large impact on reducing air pollution. It is comprised of 32.5 percent urea and 67.5 percent de-ionized water that, when sprayed into the exhaust stream of diesel engines, turns mono-nitrogen oxides (NOx) emissions into harmless nitrogen and water.
 
But just because DEF is not hazardous isn't the end of the story when it comes to storage and handling. DEF is corrosive for some metals, including carbon steel, aluminum, copper and zinc. So it should not be stored or dispensed with anything that contains these materials. ISO.org offers some details about these materials at http://www.iso.org/iso/catalogue_detail.htm?csnumber=40793.

Components in DEF Nozzles


The components used in DEF nozzles are more expensive than those used in conventional fueling systems. Husky offers a stainless steel nozzle with materials that are 100 percent compatible with DEF, a light-weight Polymer DEF nozzle with an Acetal body that complies with ISO Standard 22241-2:2006, and a new version of its popular X family of nozzles that contains the essential components for handling DEF. The variety of available DEF nozzles provides options to meet any dispensing situation.

DEF can cause dispensing equipment to clog since the urea-based fluid  will crystalize outside its optimum temperature range of 12-86 F. Husky engineers solved the problem by designing the only DEF nozzle in the industry, the company's stainless steel model, with removable cartridge assemblies for critical components that come in contact with DEF. Simply changing the affected modular part keeps the DEF flowing when dipping a clogged nozzle in de-ionized water doesn’t solve the problem.

DEF storage requires the same considerations as it relates to components. Benecor was the first manufacturer in North America to offer comprehensive storage and dispensing options for DEF. The full line of Benecor products is available for review at http://www.husky.com/benecor/
