This company recently shipped a series 4000 Recirculating Heat Treating Oven to a machine parts manufacturer for stress relieving. The model 42-M24 features a stainless steel liner forming the interior 12 x 18 x 24 in. chamber. The liner baffles the work load from the fan and heating elements to create a horizontal airflow of uniform heat throughout the chamber.
Heating elements of coiled low-watt-density wire are held in easy-to-replace element holders located on the side walls. The oven is lined with multilayered lightweight firebrick and mineral wool block insulation to maximize heat retention. Precision heating is obtained with a Honeywell digital time proportioning controller, along with a digital over-temperature safety system and soak timer. A hearth with stainless steel rollers assists in loading and unloading the product. The unit is sealed with a horizontal swing door with adjustable latch for a firm seal. This freestanding floor oven is ruggedly built with heavy sheet metal shell construction and structural reinforcements.
