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.

Features of model series CLM

Door safety switch with positive break

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

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 four-layer premium insulation for low energy consumption
and rapid heating, even 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:

Inspection hole in door (including bung)

Hardening box

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
