Gas-Fired Box Furnace

Lindberg gas-fired, semi-muffle, box furnaces have proven themselves for years to withstand the most rigorous handling and heaviest of operating schedules. These furnaces are fired from underneath the hearth by means of a series of gas burners equipped with individual gas pilots. Hearths made of heavy fire-brick slab to prevent any direct flame infringement on the work. Gas burners are staggered from side to side of the furnace and are spaced as such to ensure maximum temperature uniformity throughout the work chamber. All accessory gear such as combustion air blowers, instrument mounting panels, indicating or recording controllers, or excess temperature cutouts can be included with each furnace. Instrument panels are pre-wired at the factory for trouble-free setup and operation. Temperature range to 2000°F (2500°F optional).
