KK-DH Series

The KK-DH Series by Linn High Temp is a high-performance rotary hearth air furnace, designed for efficient and continuous operation. It features additional loading/unloading doors that minimize heat loss, enabling seamless reloading by a single operator or robot.

The furnace is insulated with a combination of ceramic light stone and microporous silica for optimal thermal efficiency. Heating is provided by durable spirals of Ferron-chromium-aluminium wire, ensuring reliable high-temperature operation. Temperature is precisely monitored using a Type K thermocouple housed in a ceramic protection tube, supporting operation up to 1100 °C.

Standard Options:

  • Control: Different temperature controllers, data recording
  • Exhaust treatment

Main application:

  • For continuous processes, especially dewaxing, sintering and preheating of lost-wax casting moulds.
  • Preheating for forging.
