Boiler Efficiency Improvement through Linkageless Control

We will review how the air/fuel ratio system works on your boiler, and why a "jack shaft" system is inefficient and wastes energy. You will also learn why mechanical linkage systems can be adjusted to match your boilers' efficiency curve. This webinar will help you understand how the "linkage-less" system works and how to determine if your boilers are a candidate for 4-10 %
