Multi-Purpose Chamber Sealed Quench Furnace
Flexible batch heat treatment

Aichelin Unitherm chamber furnaces are used wherever components are treated in batches and frequent product changes are required. These furnaces enable precise temperature control and can be configured for various heat treatment processes. This gives chamber furnaces a high degree of flexibility for changing processes and batch sizes.

More Technical features

  • Single Chamber / Double Chamber SQF.

  • In-Out Design / Straight Through Design.

  • Hardening oil cooling with air or water.

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

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

  • No moving part in heating chamber apart from 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 motorised valve in enriching line.

  • HYPER Quench: The quench oil agitation system has draft tube which diverts the quench oil in the closed oil guide box surrounding the charge which ensures pressurised 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 VFD with 2/4 nos. agitators depending upon the size of furnace.

Frequently Asked Questions
FAQ – Aichelin Unitherm Sealed Quench Furnaces
The Aichelin Unitherm chamber furnace is an industrial heat treatment furnace that heats metal components in a closed furnace chamber under protective gas. Precise temperature control and controlled gas atmospheres achieve targeted structural changes in the material.
The Aichelin Unitherm chamber furnace is designed on principle of no compressed air and no cooling water, all electromechanical drives for doors, elevator and charge machine, no moving part in heating chamber apart from re-circulation fan and with high temperature uniformity (up to ± 5 K), maximum energy efficiency, large hardening chamber with efficient quenching technology (oil or salt) and a long service life with minimal maintenance requirements.
The chamber furnace system is used in the automotive, rolling bearing, steel, fastening technology and forging industries as well as in contract hardening shops and mechanical engineering - everywhere where reproducible hardness and microstructural properties are required.
The Aichelin Unitherm chamber furnace system is controlled via the integrated PLC. In conjunction with a master PLC and the optionally integrable iFACE or FOCOS 4.0 process control system, fully automatic process management and recording of temperature and C-level progressions, as well as seamless documentation for quality assurance, is possible.
Yes – the Aichelin Unitherm chamber furnaces can operate without cooling water, with energy-efficient heating and optimized gas consumption. This conserves resources and reduces emissions.
