Designed for batch heat treating small loads of low carbon steel, the Model RD7-KHE24 bench-style box furnace with 7 kw power, heats to 2,200°F with easy-to-replace wire wound heating elements in removable holders. A horizontal swing door seals the 24 x 14 x 12-in. chamber. A ceramic hearth plate supports the work load and protects the floor brick. The Honeywell digital temperature controller with safety microswitch and on/off main control switch are housed in a NEMA 1 side-mounted panel, and a rear-mounted Type K thermocouple senses chamber heat.
The RD7 Series can be purposed to various heat treating operations including:
- hardening
- drawing
- tempering
- or annealing of steel
