Eclipse Line Burners are premix, retention type burners designed for applications where heat must be distributed over a large area. They are especially suited for oven, kettle, and either recirculating or non-recirculating air heating applications. Capacities range from 19,000 to 335,000 BTU/hr per lineal foot (based on 70% of required air in premix) depending upon the mixture pressure used. Eclipse Line Burners are available in 6" and 12" straight sections; side and bottom inlet straight sections; bottom inlet crosses and tees; and 6" 90 degree elbows.
