INDUSTRIAL-LINE CLM model series annealing and hardening kilns, up to 1,300°C

The CLM model series is designed for annealing and hardening in normal or protective gas atmosphere operation. The heating elements of the CLM kilns are on support bars. The multi-layer insulation structure guarantees low energy consumption during annealing and hardening.
The steel frame is extremely robust, and the housing design with rear ventilation provides excellent corrosion protection. The use of stainless steel supports this protection to a considerable extent. The low surface load of the Kanthal heating elements leads to less wear and tear and a long service life.

KITTEC Glüh- und Härteofen CLM 50

Features of model series CLM:

Türscharnier zwangstrennend

Door safety switch with positive break

KITTEC Edelstahlbauteile

Stainless steel side panels with rear ventilation for low outside temperatures fulfil the industrial standards

KITTEC Ausmauerung

Continuous mortar-free brick lining reduces cracking

Further options of model series CLM:

  • Kanthal heating elements on support bars in the base and at both sides
  • High-quality and innovative five-layer premium insulation for low energy consumption and the fastest heating, also in the upper temperature range.
  • Stable stainless steel structure
  • Hearth heating covered and protected by SiC plate
  • Central exhaust cowl at rear for exhaust pipe or hose
  • Heating element protection, 50 mm high at both sides
  • Stainless steel sheet as shelf space on top of the kiln door (up to CLM 90)
  • Lightweight refractory brick ASTM 26 in door frame reduces wear and tear
  • Perforated sheet metal on the kiln to prevent moisture build-up
  • Flexible door seal protects the brick lining
  • Kiln housing with rear ventilation protects from corrosion and lowers the outside temperature
  • Quiet switching procedures thanks to electronic semiconductor relay (up to CLM 30)
  • Heat shield as protection against heat radiation
  • Customised products possible at any time

Optionally available:

Schauloch in der Tür

Inspection hole in door (including bung)

KITTEC Härtekasten

Hardening box

KITTEC Härteofen CLM 20 mit Atmosbox

Atmos box

Further options of model series CLM:

  • 4 crane eyelets including frame reinforcement
  • Manual exhaust flap
  • Exhaust or supply air flap, automatically controlled (via TC)
  • Cooling fan, manually or automatically controlled (via TC)
  • 2-zone or 3-zone controller
  • Temperature selection limiter (watchdog)
  • APM heating elements and/or Alsint support bars
  • Counterweights at side instead of rear
  • Higher side heating element protection (2/3 SiC instead of 1/3 Cordierite)
  • Electro-pneumatic lifting door (with foot switch)
  • Semi gas tight version including protective gas connection
  • Semiconductor relay (noiseless)
    An electronic semiconductor relay is used instead of the electric contactor, and makes noiseless switching procedures possible during firing. Standard up to CLM 30, optional from CLM 50 to CLM 670.
  • Maximum temperature 1,350 °C or 1,400 °C
    Bricks, heating elements and insulation designed for 1,350 or 1,400 °C
  • Different controllers available

Additional Equipment:

KITTEC Härtetisch

Hardening bench

The KITTEC hardening bench is available in different versions:
• Small hardening bench HS-S (oil and/or water basin optional)
• Large hardening bench HS-B including oil and water basin
• Bench dimensions without basin: Height 610 mm, depth 735 mm, width 750 or 1,300 mm
• Basin volume approx. 55 l, including charging basket with dripping mechanism
Optionally available:
• Fan set for forced cooling (for HS-B only)
• Heating element for water and/or oil bath including thermostat (3 kW, 230 V)
