Safely Transfer Diesel Exhaust Fluid Using DEF Urea Pump System
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 […]

Exceeding the Competition
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 […]
Return pumps: Not just for returning fuel
Are there any fuel oil handling systems that don’t need return pumps? Are there any advantages to not having return pumps? While it is true that I have worked on system designs and executions that have not included return pumps, my general answer is “no,” there are not any advantages. And there are many different functional reasons why, […]
3 Reasons to have a Linkageless Control System in Your Boiler Room
A linkageless control system uses a burner with individual servos to control fuel and air ratios, and provide more savings to the end user. This technology can cut boiler room costs and solve end-user headaches. Here are three reasons to choose linkageless controls: Higher efficiency: O2 levels may fluctuate, but will always return to position of highest fuel […]
Sustainability: Carbon Footprint and Emissions Reduction
Top tier American college chooses Preferred Utilities as their partner in a major burner and controls retrofit project on their existing (700 hp) Johnston Boiler. With the installation of the dual fuel Preferred Utilities API-InjectAire burner, the college will reduce its electric consumption on this unit by more than 75% while increasing combustion efficiency by more than double. […]
Liquid Wood: The Renewable, Carbon-Neutral Fuel Alternative That Is Finally Ready to Burn
Discussions of sustainable energy don’t often include food flavorings. However, the same process that creates liquid smoke—the stuff you can buy at the grocery store to add a smoky flavor to just about anything—can produce liquid wood, a very environmentally friendly fuel. You may not have heard of liquid wood because, until very recently, it was quite difficult […]
