About the ENDURA+
Fulton's ENDURA+ extends the condensing firetube family to 2,500,000–12,000,000 BTU/hr with the model inventory EDR+2500, 3000, 4000, 5000, 6000, 8000, 10000 and 12000. The page prints a 'patent-pending stress reliever', variable primary flow and up to 15:1 turndown with O2 compensation.
Knockdown capability is offered on models up to 6 million BTU/hr, letting those sizes fit through a standard doorway for retrofit plants. The Specs tab carries an AHRI Thermal Efficiency (%) table whose per-model values are not re-typed in Boilers.ca's research file, so no structured percentage is printed here.
The page's documents tab publishes the brochure, I&O and specification as public PDFs; the current brochure is linked from this hub.
