• Parallel upward opening door, hot inside of door always facing away from the operator
• Furnace insulation made of high-quality fibre materials with low thermal mass
• Door surround made of robust lightweight refractory bricks
• Abrasion-resistant lightweight refractory brick in the kiln floor
• Delivery includes ceramic base plate
• Powerful silicon carbide heating elements in both furnace sides, fast heating rates
• Switching via semiconductor relay, particularly precise kiln control, wear-free, noiseless
• Exhaust air opening in the kiln ceiling

Thermconcept rotary tube furnace D-ROK, 1100 °C
Hinged and with rotating tube

Rotate, tilt, flip
D-ROK models are hinged rotary tube ovens with adjustable rotation speed and inclination angle. Due to the hinged design, tubes can be changed quickly.

• Ovens prepared for a maximum tube outer diameter of 50, 75 and 100 mm, individually adapted tube diameters are possible on request
• Heated lengths from 500 mm, can be extended in segments as required
• Can be used as batch or continuous furnace, rotation speed adjustable
• Designed for horizontal operation with adjustable inclination angle for continuous throughput processes
• Insulation made of high-quality fibre modules with integrated heating elements for direct heat radiation on tube and charge
• High-quality furnace housing with integrated switchgear and drive unit, mounted on the inclinable base frame
• Entire furnace unit on base frame with castors, thus easily movable
• Switching of heating elements via semiconductor relays for precise furnace control, wear-free, noiseless

Thermconcept Elevator Furnace ELHT, 1600 °C

• Table-top and floor models with electro-mechanically driven furnace table, pressure- and vibration-free movement, opening downwards, thus low heat radiation to the user
• Very good temperature uniformity due to all-round heating of the cubic furnace chambers
• Double-walled housing construction with rear ventilation, extraordinarily low outer wall temperature
• Furnace insulation made of high-quality aluminium oxide material with very low thermal mass for rapid heating and cooling
• High-quality heating elements in all sides with free heat radiation into the furnace chamber
• Heating elements switched by solid-state relays or thyristors for precise, wear-free and noiseless furnace control
• Exhaust air opening in the furnace ceiling
• Floor models on castors

Convenient loading at high temperatures
Elevator ovens with volumes of 8 and 16 litres can be opened conveniently and quickly and then loaded hot. At the same time, the oven design allows 4-sided heating with high temperature accuracy.

Thermconcept High-Temperature Tube Furnace ROHT, 1700 °C
with exchangeable tubes

• Tube diameters from 40 to 75 mm
• Heated lengths of 200 mm, 300 mm, 400 mm and 600 mm
• Designed for horizontal operation, vertical version available on request
• Double-walled casing construction with forced rear ventilation, extraordinarily low outer wall temperature
• Furnace insulation made of high-quality aluminium oxide material with very low thermal mass for fast heating up and cooling down
• Very powerful heating via _MoSi2 heating elements, with free heat radiation onto the tube and the sample, high temperature accuracy and long life of the heating elements
• Furnaces are supplied as standard as table-top models with a tube made of 99.7 % _Al2O3
• High-quality furnace housing, partly with stainless steel cladding on the sides
• State-of-the-art switching and control technology via thyristors in phase-angle control mode for very precise, wear-free and noiseless furnace control
• Switching and control system for horizontal furnaces mounted in the lower housing area

Highest temperatures
Tube furnaces with_MoSi2 heating elements are designed for temperatures up to 1700 °C and 1800 °C. Tubes made of Alsint (C 799) with inner diameters of 40, 50 and 75 mm are included in the scope of delivery.
Available in horizontal and vertical design.
Horizontal furnaces can also be supplied in multiple zones (on request).
