Webster Engineering Introduces New Temp-A-Trim(TM) Air Density Trim System

Press release date: May 09, 2008

WINFIELD, Kan., - Webster Engineering, a leader in combustion technology and equipment, introduces the new Temp-A-Trim(TM) air density trim system. The Temp-A-Trim(TM) system efficiently manages the fuel/air ratio in industrial and commercial burners, to create dramatic fuel savings of up to three 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 new Temp-A-Trim(TM) system senses combustion air temperature and automatically varies burner fan speed to create a constant mass airflow. This constant mass airflow maintains optimal combustion efficiency in the burner, regardless of the combustion air temperature. Further savings are generated as a result of reduced electrical usage. Additional features and benefits of the Temp-A-Trim(TM) system include: Easy installation, with no special setup or programming required Reduces need for costly seasonal tuning of burners Reduces noise levels in boiler rooms Compatible with linkage or linkage-less controls Provides lower cost, complexity and maintenance than typical O2 trim systems
