The 8000 AM Series dual chamber furnace operates in an inert atmosphere to minimize scale and oxidation on most tool steels, which is ideal for cyclical or production-type applications.
Model 86AM-K24
Model 85AM-K24 with optional strobe light
Options
Flow meters, regulators, oxygen analyzers, dew point indicators, muffle thermocouples, cascade, and multi-zone control systems, supervised flame curtains, supervised burn-off systems, program controllers, over temperature safety systems, cooling systems, timers, recorders, quench tanks, alternate door arrangements, computer interface, special voltages, gloves and tongs.
Unique “Space Saver” design offers the convenience and economy of two independently controlled chambers in one packaged assembly. The upper chamber (Hardening) is equipped with an alloy muffle for operation with a positive flow of 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 in the work chamber, reduces atmosphere consumption, and shortens purge time. The AM models are ideal for cyclical or production-type applications.
The lower chamber (Tempering) is complete with a stainless steel liner and fan to recirculate the heat for uniform temperature. Available at operating temperatures of 800°F(88), 1200°F(82), 1400°F(84), and 1600°F(86). Ideal for Tool Rooms and Schools, providing a complete heat treat station in one furnace.
Ruggedly constructed and rated for work loads up to 50 lbs. per square foot of hearth area. All models are completely wired, assembled, test fired and shipped ready for connection to main power supply. Compact design, fast installation, and simple, safe, dependable operation. All models will operate in inert atmosphere. Flammable atmosphere may be used with the addition of an Atmosphere Safety System per NFPA Code 86 C.
Standard Features
Welded sheet metal single shell construction.
Both chambers are designed with the same working dimensions.
Heavy gauge coil wound low-watt density heating elements for longer life.
High-grade alloy muffle with inlet pipe and front flange.
Multi-layered energy efficient lightweight firebrick and mineral block insulation for maximum heat storage and minimum heat loss.
Elements mounted in easy-to-replace holders located on side walls and below the hearth for uniform temperature in the upper chamber.
Silicon carbide hearth plate for muffle support and thermal transfer from floor elements in the upper chamber.
Manual vertical lift door (8000 AM) and double pivot horizontal swing doors (85AM & 89AM) with high-temperature ceramic fiber gasket on the upper chamber.
Safety micro-switch shuts off power to elements and fan on lower chamber when the door opens.
Honeywell digital temperature controller with type K thermocouple and magnetic contactor on each chamber.
Controls are mounted in a side-mounted NEMA 1 panel and operate on 115 volts.
