Premium Performance
The furnaces of APEX Series boilers are of large diameter and ample length.
This, along with the full water-cooled rear chamber, ensures that the
furnace absorbs much more heat, maximizing efficiency and minimizing pollutants,
while allowing tubesheets to have a cooler, longer life.
