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 […]
JC-30D Opacity Monitor: New and Improved!
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 […]
A New York City Public School central heating plant moves on their Local Law 87 goal

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 […]
Special Combustion project for another American based manufacturer
Pictured: one of two Preferred Special Combustion burners and control cabinets to be installed at an American steel manufacturer in Ohio, and utilized on twin super heaters used in the steel manufacturing process. The burners, atmospheric element style heaters, use stoichiometric combustion to produce heat input for the super heater. The Preferred UV Self-Checking Quanta-Flame Scanner monitors the flame. […]
