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.

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.

The control cabinets are PCC-IV based, multi-loop controllers combined with the Preferred M-85 Flame Safeguard Controller and Preferred Quanta-Max, a state-of-the-art microcomputer-based burner management system (BMS).

These components work in tandem with the scanner and other safety products on the burner and fuel train to produce safe, stable, and efficient combustion process.

A high efficiency and very “green” 50 KPPH Packaged Burner System about to ship out to one of the world’s largest privately held companies. 

Preferred Special Combustion Engineering (PSCE) provides a complete package combustion system for new or OEM watertube boiler projects. A complete packaged burner system (including controls) all from one source will optimizes burner to boiler special interface, allows for maximum pre-wiring of the system devices, provides a more complete checkout process, and minimizes field errors and commission time.

These often overlooked factors add up to real dollars saved.
