Lucifer Furnaces offers its series 2055 top-loading pot furnaces for salt bath heat treatment. The furnaces are available in 10 standard sizes and are said to provide quality surface protection while minimizing scale, oxidation and decarburization.
The furnaces are constructed with multilayered firebrick and mineral wool insulation for maximum heat storage and low outside skin temperature. Units include a stainless steel pot designed with a flange for sealing against the roof plate, which is constructed of heavy-gauge steel plate to withstand warping and distortion from chamber heat. Large models are constructed with a roller-mounted lid to reduce bath surface heat loss during idle periods; the lid track extends beyond the back of the furnace for unobstructed access into the chamber. 

Heavy-gage, coil-wound, low-watt density heating elements in easily removable radiant panels are located on all four side walls of the heating chamber, the company says. The elements are divided into several zones to provide uniform heat to 1,500°F. Separate thermocouples monitor both chamber and pot medium temperatures. Side-mounted, power-regulating equipment includes a magnetic contactor, a 230- or 460-V to 110-V control transformer, terminal blocks, instrument fuses and power connection terminals. Temperature controls include a Honeywell ¼ DIN microprocessor-based digital time proportioning temperature controller mounted in a separate NEMA 1 enclosure. An over-temperature safety system option prevents thermal runaway. The furnaces are completely wired, assembled and shipped ready for connection to a main power supply.
