Diesel Exhaust Fluid (DEF) was developed to help keep heavy-duty diesel fueled machinery like boilers operating within federal emissions standards. At the chemical level, DEF is a combination of 67.5% de-ionized water and 32.5% urea that transforms harmful nitrous oxide emissions into harmless water and gas.

Urea is an organic chemical compound produced as waste by the body after metabolizing protein—but the urea used in DEF is not (despite some confusion on the subject) derived from human or animal urine. For nearly two centuries, scientists have been able to create synthetic urea, which is much more appropriate for the DEF application.

DEF isn’t actually a fuel additive, and it never comes in contact with diesel. Rather, it is stored in a separate tank and is pumped into the exhaust stream of diesel machinery to break down dangerous NOx emissions into safe nitrogen and water. This process is called Selective Catalytic Reduction (SCR).

Changes in EPA emission standards have required diesel burning machines to reduce their output, and SCR is the technology of choice for this purpose. As emission standards have continued to expand to include off-road vehicles, generators, and a variety of engines, the use of DEF is becoming more and more widespread.

To properly deliver DEF, the Diesel Exhaust Fluid Urea Pump system is designed to safely and effectively transfer DEF fluid from a tank to diesel equipment, helping facilities comply with strict NOx emission regulations. Constructed using stainless steel piping and pumps, the DEF system lasts in even the most abusive outdoor environments. We proudly make DEF Urea Pump Systems in the USA. Here are the specifications:

Flow Capacity: 100-300 GPH
Pressure Capacity: 100 PSI
Pump Type: Centrifugal with Stainless construction
Standard Accessories: All Stainless Steel
Inlet Strainer
Outlet Check Valve
Leak Sensor
Inlet Suction Gauges

With innovations such as DEF implementation and SCR, support from Preferred can help you adapt your systems and take advantage of the most efficient and effective ways of reducing emissions.

 

With the NEW and improved Opacity Monitor model JC-30D with Automatic Calibration, LED light source, and light detector, no onsite operator is required to calibrate the system. When the system receives a signal from the burner fan, it auto calibrates opacity by itself, compensating for dirty lenses.

Auto-Calibrate coupled with the new brighter LED light source allows the lenses to go without cleaning for up to 9 times as long as previous versions. This saves on labor cost for unmanned boiler rooms and operators can focus on other tasks in their boiler room. The improved light sensor now directs light only from the light source and eliminates misreading from tramp light, which can cause problems in the boiler room.

The new JC-30D is an easy retrofit for older JC-30D models, as well as other opacity monitors. Durable quality and made in the U.S.A.!

 

Our SECOND burner and controls retrofit for Bates College on one of their existing 700 HP Cleaver-Brooks™ boilers so they can burn ENSYN Renewable Fuel Oil (100% renewable fuel source derived from trees) as their primary heating source! With our help, Bates is on the verge of reaching their 2020 emissions and carbon reduction milestones while increasing combustion efficiency and reducing electric consumption.

An innovative, low-cost combustion solution to meet sustainability goals, emission reduction requirements, and extreme efficiency improvements.

This installation is at an American college with aggressive sustainability goals. Our solution for them–a burner and controls upgrade on one of their existing 700 HP Cleaver Brooks boilers to achieve their emission and carbon reduction milestones, while increasing combustion efficiency and reducing electric consumption. This upgrade will NOT require the removal of the Cleaver Brooks front or rear doors, but acts as a direct replacement “insert” for the existing Cleaver Brooks burner, while reusing the existing Cleaver Brooks combustion fan and making no cuts or modifications in the original front door.

This specialized API-Ranger burner and controls upgrade will allow the college to burn ENSYN Renewable Fuel Oil, an 85% carbon neutral renewable fuel, along with natural gas or #2 oil.

American made and supported, our technological advancements continue to out-pace the competition.

 

For reliability, longevity and unmatched service, choose Preferred!

This Preferred JC-CDDF2 chief dispatcher model has been in service since the 1970’s in a Newport, RI facility. When one of the relay sockets finally broke, they called Preferred.

Although this unit has been out of production for nearly 20 years, we still had replacement parts in stock and original wiring diagrams for the installation of the new parts.

Built in the USA and built to last!

 

The Coen “AC” valve has been nearly irreplaceable because of it complicated, characterized design and expense – until now!

As just one of its capabilities, the Preferred Voluvalve directly replaced and exceeded the performance of the Coen “AC” valve at this recent project site.

The Voluvalve can be made to drop in as a direct replacement for a COEN “AC” valve or be used in a parallel positioning type control strategy as was utilized at this jobsite with our BurnerMate Universal Combustion Controller and Flame Safeguard System. 

Using a custom and proprietary drilled hole pattern inside the valve, it allows the valve to repeatedly, and accurately match the optimal efficiency flow rate, and fuel air ratio characteristics for any burner.

Designed and Manufactured in Danbury, CT USA and started up in the field, if requested, by our application engineers. Contact us for more information.

 

Preferred’s products and online tools can help Florida nursing homes and assisted-living facilities (ALF) meet state proposed fuel storage legislation.

After emergencies during and following Hurricane Irma, B 7028 and HB 7099 make permanent rules that require every nursing home and ALF in Florida to have emergency generators, keeping residents safe and their facilities functional at least until help can be sent to them after disasters. (Florida Governor’s statement)

The online tools provide a head start on emergency generator system design and planning. Our fuel load web tool calculates main tank storage size based on generator kW.

We offer a web tool to check suction conditions and size fuel oil pumps and piping systems here:

And finally, you can generate a complete Facility Fuel Oil specification section based on Preferred products.

Preferred’s ATPSF duplex pump sets include integrated pump controls and optional tank gauge and leak detection systems. We also offer day tanks, return pumps, fill boxes, and all the accessories to make a complete fuel oil handling system.

Although our engineers can custom design a system for any number of generators, our standard pump control program can handle up to two-day tanks and up to two main storage tanks right out of the box. With no programming and minimal engineering required, these systems are available with very short lead times.
