More Technical features

  • Single Chamber / Double Chamber SQF.

  • In-Out Design / Straight Through Design.

  • Hardening oil cooling with air or water.

  • Designed on the principle of no compressed air and no cooling water.

  • All electromechanical drives for doors, elevator and charge machine.

  • No moving part in the heating chamber apart from the re-circulation fan.

  • Temperature uniformity up to ± 5 Celsius in the usable space.

  • Fully Automatic no man operation plants through iFACE (Intelligent Fully Automatic Controlled Equipment).

  • Carbon potential control +/- 0.02% during carburising through a motorised valve in enriching line.

  • HYPER Quench: The quench oil agitation system has a draft tube that diverts the quench oil into the closed oil guide box surrounding the charge, which ensures pressurized and uniform oil-flow circulation throughout the charge during quenching. The propeller diameter is 325 mm, driven by 5.5 / 7.5 kW motors through a VFD with 2 / 4 agitators, depending on the size of the furnace.

Frequently Asked Questions
FAQ – Aichelin Unitherm Sealed Quench Furnaces
Aichelin Unitherm offers a state-of-the-art Sealed Quench Furnace equipped with advanced safety features to ensure reliable and safe operation. Designed on the principle of no compressed air and no cooling water. The system continuously monitors furnace pressure 24/7 to maintain safe operating conditions. In the event that the furnace pressure falls below 0.5 mbar during quenching, an automatic nitrogen purging system is activated to protect the furnace atmosphere and ensure safe operation. These integrated safety features help safeguard equipment operation and maintain high product quality.
The Aichelin Unitherm Sealed Quench Furnace is designed for maximum efficiency, reliability and safety. Its low operating costs are achieved through minimal utility consumption, with no requirement for compressed air or cooling water. Robust electromechanical drives for the doors, elevator and charge machine ensure dependable operation and reduced maintenance. Even during prolonged power outages, furnace safety is maintained through automatic nitrogen purging in the heating chamber.
The Aichelin Unitherm Sealed Quench Furnace features an advanced recipe-based control system seamlessly integrated with the PLC and HMI. Critical process parameters such as furnace temperature and carbon potential are automatically managed by Eurotherm controllers using setpoints defined within the selected recipe. This intelligent automation ensures precise process control, repeatable heat treatment results, and maximum production efficiency.
