The Lindberg Gas-Fired Bell Furnaces give you flexible, efficient performance in a variety of heat treating applications. The fast heating rate, heavy load capacity, and reliable operation help you achieve fast turnaround and high productivity. The furnace is very simple and economical to operate, and is available in a wide range of sizes.

The gas-fired bell applications range up to 2150°F, with endothermic, exothermic, or nitrogen atmospheres. This furnace enables you to anneal, austemper, braze, carbonitride, carburize, harden, martemper, solution treat, stress relieve, and normalize efficiently and economically.

Features / Benefits

• Standard endothermic atmosphere system
• Emergency nitrogen gas purge circuit activates on power failure or loss of atmosphere
• Atmosphere tight continuously welded hood assembly
• Burners configured to insure a uniform heat pattern around the periphery of the alloy hood without direct flame impingement. Easy-loading chamber
• Complete, pre-wired free standing control panel with disconnect switch
• Excess temperature instrument
• Designed to meet FM, IRI, OSHA, and NFPA requirements
• Ceramic fiber block insulation reduces power consumption and boosts your productivity and efficiency with faster thermal cycling and reduced heat loss
