GLOBAL DEF SYSTEM PORTFOLIO

DIESEL EXHAUST FLUID SYSTEMS

Shaw Development, LLC manufactures various configurations of Diesel Exhaust Fluid (DEF), also known as AdBlue® Reservoir Systems. DEF systems are used to supply Selective Catalytic Reduction (SCR) systems with a catalyst compound to break down harmful NOx emissions into nitrogen gas and water vapor. These systems are the preferred method for on-road and off-road diesel vehicles and equipment users to meet increasingly strict emissions standards. Shaw manufactures eight standard cross-link polyethylene (XLPE) reservoirs as well as designs custom sizes and shapes in XLPE and stainless steel as needed. Standard tank sizes range from 5 to 25 gallons, with custom stainless steel tank designs reaching up to 250 gallons.

The core of Shaw’s DEF reservoir is the multifunction head unit. The multifunction head unit contains integrated level, temperature, and concentration sensors which can provide analog or digital outputs depending on the application requirements.

 The head includes a heating element that is powered by coolant and is capable of thawing DEF when external temperatures drop below 12°F. For special applications, additional electrical heating elements may be integrated into the reservoir system design.

Fittings, tank orientation, and kit accessories are customized to specific applications. Optional accessories include vented and filtered caps, debris guards, heated hoses, and remote fill adapters. Fill caps are blue and designed in accordance with ISO 22241.

AdBlue® Standard, for easy identification. All DEF reservoir system designs are thoroughly tested in Shaw’s state of the art test lab for functionality and meet the specific durability needs of the heavy-duty vehicle and equipment market. Shaw’s engineers have extensive experience in the development and manufacturing of innovative fluid handling solutions.

DEF Filters

Uncontaminated Diesel Exhaust Fluid (DEF) is critical for the optimal performance of the emissions control system for diesel engines. DEF is highly susceptible to contamination from dust, particles and debris from fluid refills and day to day operations. Contaminated DEF could result in damage to the emission systems components of the diesel engine. To prevent downtime and reduce maintenance costs Shaw developed cutting edge technology, Shaw’s DEF / AdBLUE® Inline Filter. The In-line Filter has proven to be a critical component for the success of Shaw’s customers.

Shaw’s DEF / AdBLUE® Inline Filter can be installed in an accessible location and filter replacement requires no special tools or training. Simply remove the old filter and install the new one in its place. The Shaw in-line filter can be installed in minutes, and it will provide extended maintenance service intervals.

Shaw’s DEF / AdBLUE® can be used in combination with the other Shaw DEF filtration products, which include the DEF cap, fill port strainer, and the in tank filter.

Shaw’s best-in-class DEF / AdBLUE® inline filter offers 5X more debris holding capacity. The most technological in-line DEF filtration solution on the market.

Shaw’s best-in-class DEF / AdBLUE® inline filter was designed with serviceability in mind. Numerous features have been incorporated to improve the customer experience.

Non Heated DEF Filters

Heated DEF Filters

The heart of the Shaw System is the Multifunction Head Unit (MFHU). To simplify design, the MFHU contains integrated level and temperature, and fluid quality (concentration) sensors . By using ultrasonic sensing technology the level sensor eliminates the problems normally associated with mechanical designs. Outputs from all sensors are fully compatible with major dosing units available today in analog or CANBUS output.

Included in the MFHU is an engine coolant powered heater to thaw or prevent freezing of DEF in conditions below 12 °F (-11 °C). The heater is designed for optimal performance to meet OEM and governmental regulations. Electrical heating is also available for special applications.

In order to meet reduced Nitrogen Oxides (NOx) emission levels, many diesel engine manufacturers have turned to Selective Catalytic Reduction (SCR) as the technology of choice. Storage , monitoring, and transfer of diesel exhaust fluid (DEF) is best handled with a single source system solution.

Optional items such as remote fill adapters and vents, lockable caps, coolant control valves, electrically heated suction, return, and pressure hoses, and mounting brackets are available to complete the DEF reservoir system.
