Air Density Trim System: Webster Combustion Technology LLC
Webster Combustion Technology LLC announced the expansion of the Temp-A-Trim™ system, the patented control system designed to deliver fuel savings of up to 3% and electrical savings of up to 30%. The Temp-A-Trim is now available on new or installed commercial and industrial boiler burners of any brand. According to the company, Temp-A-Trim works by precisely correcting for air density as the combustion air temperature changes to optimize combustion efficiency automatically. A built-in variable frequency drive (VFD) adjusts the fan speed based on incoming air temperature to create a constant air flow mass for combustion, assuring that the burner is always operating at maximum efficiency, thereby burning less fuel and reducing emissions.
The Temp-A-Trim can be retrofitted on any commercial or industrial boiler burner regardless of size or brand. It can be installed with no special setup or programming required, and it is compatible with both linkage and linkageless control systems.
