Overview
WHG Wall Hugger flat flame gas burner is designed for applications requiring even heat distribution with no flame impingement. The burner’s flame pattern promotes even heating by radiation from the furnace walls and roof. The flame hugs the wall allowing the burner to be placed close to the load.
Features & Benefits:
