The 7000 AM Series furnace is designed for daily use in an inert atmosphere to minimize scale and oxidation on most tool steels, ideal for cyclical or production-type applications.
Model 7AM-I12
Model 7AM-C12
Options
Flow meters, regulators, oxygen analyzers, dew point indicators, program controllers, over temperature safety systems, timers, recorders, loading systems, fiber insulation, quench tanks, alternate door arrangements, forced cooling systems, computer interface, special voltages, gloves, tongs and foil wrap.
Bench and floor models are equipped with an alloy muffle for operation with a positive flow of protective atmosphere to 2050°F. The alloy muffle separates the chamber refractory and heating elements from the workload and atmosphere to minimize scale and oxidation on most tool steels. This design achieves lower dew points, reduces atmosphere consumption, and shortens purge time. The AM models are ideal for cyclical or production-type applications.
Ruggedly constructed and rated for work loads up to 25 lbs. per square foot of hearth area. All models are completely wired, test-fired, and shipped ready for connection to main power and regulated atmosphere pressure of 5 PSI. Compact design, easy installation, and simple, safe, dependable operation. All models will operate with inert atmosphere. Flammable atmosphere may be used with the addition of an Atmosphere Safety System per NFPA Code 86 C.
