Webster Combustion Technology
This company has expanded its patented Temp-a-Trim control system (photo) so that it is compatible for installation on any brand of commercial or industrial boiler. The Temp-a-Trim system is designed to deliver fuel savings of up to 3% and electrical savings of up to 30% in boilers, says the company. Temp-A-Trim works by precisely correcting for air density, as the combustion air temperature changes to automatically optimize combustion efficiency. A built-in VFD adjusts the fan speed based on incoming air temperature to create a constant airflow for combustion, assuring that the burner is always operating at its maximum efficiency. — Webster Combustion Technology LLC, Winfield, Kan.
