Refractory-Supported Heater consists of high-quality, helically-wound, iron-chrome-aluminum metallic alloy resistance heating elements fully embedded in a strong, highly stable, high-temperature refractory body. Produced on a custom basis for OEM thermal process equipment and end-users with unique requirements, Heaters routinely operate to temperatures of 1100°C with power loadings of 2 kw/ft². Some designs successfully carry 4 kw/ft² power density at an operating temperature of 1100°C These rugged heaters feature self-supporting construction and are precision-fabricated for long heater life. The metallic heating element is carefully prepared prior to being cast into the refractory to ensure uniform heat over the entire surface of the unit. The base refractory has outstanding abrasion resistance and is ideal for applications where the heating element might be subject to mechanical damage or being splashed with molten metals. The high thermal mass of the heater minimizes fast thermal changes that can be experienced with low-mass heaters. Heaters are immune to damage from electrical shorting due to contact with materials being heated.

For annealing and hardening of larger parts, for example heavy cast parts or tool steel dies to temperatures between 800 °C and 1100 °C, we recommend our bogie hearth furnaces with radiation heating. The bogie can be loaded outside the furnace. When the design includes an electro-mechanical lift door and a motorized bogie, the furnace can be opened while hot and the load can be removed for cooling or quenching. When several bogies are used together with a second door or bogie transfer system, one bogie can be loaded outside the furnace while the other bogie is in the furnace. This shortens process times and the residual energy of the furnace can be used when the new charge is heated. Tmax 900 °C or 1200 °C Dual shell housing with rear ventilation, provides low shell temperatures Swing door hinged on the right side Heating from five sides (four sides and bogie) provides for a optimum temperature uniformity Bogie heating receives power via blade contacts when driven in Available In LPG/PNG/HSD/ELECTRIC capacity from 0.5 Mt to 15 MT
