Furnace by Type

Batch Atmosphere Furnaces

Gasbarre Thermal Processing Systems manufactures, installs, and commissions a full range of batch atmosphere products. Our product line covers a wide range of different processes including tempering, annealing, nitrocarburizing, nitriding, stress relieving, normalizing, steam treating, and inert atmosphere processing. These products are highly energy-efficient and can be gas-fired or electrically heated. They are available in standard configurations and sizes or can be custom designed. We can provide the ideal product to process your specific parts based upon your loading method, process, temperature, and atmosphere requirements.

Batch Vacuum Furnaces

Designed for many thermal processes, the electrically heated batch vacuum furnace is available in a multitude of configurations. The most basic configurations are the front and top-loading single chamber styles where work is loaded into and out from the same door. These are designed for high-temperature applications such as brazing, annealing, carburizing, hardening, tempering and are supplied with graphite or ceramic insulation packages. Evacuation systems include rough pumps, boosters, and diffusion pumps when required. Being modular in design, independent quench chambers may be added to the basic heating chamber. The quenching mediums may be gas, pressurized gas, and/or oil. Isolation of the modules (temperature and vacuum level) may be accomplished with an internal vacuum door.

Continuous Atmosphere Furnaces

Gasbarre Thermal Processing Systems manufactures, installs and commissions a wide range of continuous atmosphere products which include mesh belt, pusher, and roller hearth furnaces. Our product line covers a wide range of different processes including sintering, brazing, annealing, glass-to-metal sealing, carburizing, carbonitriding, hardening, inert atmosphere processing, normalizing, stress relieving, tempering, and drying. These products are highly energy efficient, and can be gas-fired or electrically heated. They are available in standard configurations and sizes or can be custom designed. We can provide the ideal product to process your specific parts based upon your process, temperature, atmosphere, and throughput requirements.

Continuous Vacuum Furnaces

The continuous vacuum furnace essentially transforms the batch vacuum furnace into a straight through furnace. Work is no longer processed into and out from the same side – rather work is loaded into the entry side and unloaded from the exit side of the furnace. Modules consist of load/evacuation chambers, preheat and high heat chambers, multiple heat position chambers, and quench (oil and/or pressurized gas) chambers. Small batches are therefore indexed in a continuous fashion making this style furnace highly productive in processes that range from annealing, brazing, carburizing, sintering, to hardening. With the continuous vacuum furnace, the heat chamber typically remains hot and under vacuum making for a highly efficient and pure system.
