MTH Series – High-Turndown, Dual-Fuel Burner for Medium-Pressure Systems

MTH Series burners are designed for medium- to high-pressure boiler systems requiring precise modulation, high turndown, and flexible fuel handling. With input capacities from 2.1 to 42 MMBtu/h, they support natural gas, propane, and #2 oil, offering 10:1 turndown on gas and 8:1 on oil. Ideal for hot water and low-pressure steam systems, MTH burners combine high static pressure fans, full modulation, and low excess air operation to ensure consistent, efficient combustion. With compact, quiet operation and UL/cUL approvals, they’re suited for institutional, commercial, and light industrial applications.
