Carbolite Customized Products

Laboratory top hat furnace

• Maximum operating temperature - 1100°C
• Wire elements embedded in vacuum formed fibre side walls
• Chamber dimensions : 400 (h) x 350 (w) x 350mm (d)
• Electrically operated raise / lower mechanism for furnace chamber
• Loading height with furnace in raised position : 500mm

Thermal cycling rig

• For long term thermal cycling at temperatures up to 1200°C to evaluate performance of new bond-coat/ceramic layers
• Vertical tube furnace with electrically operated hearth below it, which holds the samples of coatings for evaluation
• When the thermal cycle starts, the samples are raised into the hot zone and the furnace is heated to 1135°C
• After one hour at temperature, the samples are lowered into a quench area and cooled to 80°C - they are then automatically raised back into the hot zone and the cycle starts again
• Each thermal cycle lasts approximately 70 minutes and up to 20 cycles/day can be completed in 24 hours

Split tube furnaces

• Vertically split furnace designed for tensile testing
• A 10mm wide slot on the split line of the two halves accepts an extensometer
• Working zone : 80mm diameter x 70mm heated length
• Maximum working temperature : 1600°C
• Heated by molybdenum disilicide 'U' tupe elements
• Single zone control
• Power rating : 1.4kW

Rotating tube furnace

• Specially designed tube furnace for powder processing
• Maximum operating temperature 1200°C
• Heated length of 1000mm, divided into three independently controlled zones to allow a temperature gradient to be achieved
• Total work tube length is 1800mm
• Up to 5 litres of material can be processed at any one time under an inert atmosphere
• A rotating work tube, which can be tilted to control throughput, ensures there is minimal agglomeration
• The speed of rotation can be adjusted from 2rpm to 12rpm and the angle of tilt between 0 - 10° from horizontal
• Material is fed into the 75mm diameter work tube via a vibrating feeder equipped with a speed controller and five litre hopper

Rotating tube furnace

• Designed to cure coatings on fine powders which are used for vitreous enamelling
• Maximum temperature - 500°C
• Tube heated length - 2000mm
• Temperature uniformity ± 10°C over central area
• 3 zones
• Power rating 90kW

Paternoster incubator

• Used in the mass screening of drugs by a leading pharmaceutical company
• Contains a rotating mechanism which indexes a series of horizontal trays
• The front of the incubator contains a 'posting slot' to allow a robot to place the plates on the Paternoster support trays
• Sealed chamber enables an enhanced atmosphere of carbon dioxide to be maintained
• Normal working temperature 37°C (maximum operating temperature 50°C)
• Temperature uniformity better than ± 1°C
• Temperature stability better than ± 0.2°C
• Air is circulated within the chamber by a top mounted fan and air guide system
• Internal light allows inspection of the interior without disturbing the internal atmosphere

8-zone gradient tube furnace

• For the evaluation of refractories, tiles, sanitaryware, tableware and asscociated products
• Maximum temperature - 1600°C
• All zones reach 1250°C from ambient in 40 minutes
• Heated length - 800mm
• Heating is provided by 32 silicon carbide spiral cut elements (4 to each zone mounted vertically down both sides of the heated chamber)
• Maximum power 18kW

Double chamber furnace

• Two identical chambers for heating salt rings used in casting aluminium pistons
• Designed to reduce floor space & allow the unit to be positioned close to the casting station
• One chamber is used with the door being opened every few minutes to remove a salt ring, while the other chamber heats up a second batch of rings in preparation
• Maximum operating temperature : 1100°C
• Operating temperature : 700°C
• Each chamber is individually controlled and has a power rating of 7kW
• Chamber size : 235mm (h) x 240mm (w) x 400mm (d)
