The muffle is mounted on a portable cart assembly which can be easily rolled in and out of the furnace chamber. A double pivot horizontal swing door mounted on the furnace seals the chamber when the muffle is removed. The holding door maintains the chamber temperature enhancing furnace production capability for fast turnaround of the next muffle. The muffle separates the furnace insulation 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 muffle is equipped with a manually removable plug door on chambers 7"H x 7"W and smaller; larger chambers are standard with a double pivot hinge door mounted on the cart. All models are completely wired, test fired and shipped ready for connection to main power and regulated atmosphere pressure of 5 PSI. All models will operate with inert atmosphere. Flammable atmosphere may be used with the addition of Atmosphere Safety System per NFPA Code 86 C. ### Standard Features - Welded sheet metal shell construction with structural reinforcement. - 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. - Silicon carbide hearth plate for full muffle support and thermal transfer from floor element. - Plug door with high temperature ceramic fiber gasket, swing bolts, and handles for sealing against muffle flange. - Eurotherm digital temperature controller with type K thermocouple and contactor. - Controls are mounted in separate side-mounted NEMA 1 panels and operate on 115 volts. ### These Furnaces are built to order. #### [Request a quote](https://info.luciferfurnaces.com/request-a-quote?hsLang=en) to get started.
