The Temp-A-Trim™ air density trim system efficiently manages the fuel-air ratio in industrial and commercial burners to create fuel savings of up to 3 percent. Temperature changes in a boiler room, from day to night and season to season, cause significant combustion inefficiencies and at the same time combustion stability is degraded. The Temp-A-Trim™ system senses combustion air temperature and automatically varies burner fan speed to create a constant mass airflow. This airflow maintains optimal combustion efficiency in the burner, regardless of the combustion air temperature. It is compatible with linkage or linkage-less controls. No special setup or programming is required.
