LTF - Tube Furnaces - 1200°C

This range of furnaces has a maximum operating temperature of 1200°C. Heating is provided by a resistance wire element wound on to the ceramic work tube, which is an integral part of the furnace. Low thermal mass insulation is used throughout for rapid response rates and maximum thermal efficiency and stability. A rugged metal sheathed thermocouple is protected from accidental damage and allows for full use of the work tube bore. If the tube is for use with an atmosphere, or is likely to be contaminated by spillage, a separate work tube is required.

Horizontal models are suppled with the controls in the base, whilst vertical versions have a separate console.

Other lengths can be made to special order - please contact us with your details

LTF - Tube furnaces : 1400°C, 1500°C & 1600°C

Heating is provided by silicon carbide rod elements which are mounted parallel to the work tube (the work tube must be ordered separately).

The elements radiate heat directly onto the tube for rapid response rates. Low thermal mass insulation is used throughout for maximum thermal efficiency and stability.

Horizontal models are supplied with the controls in the base, whilst vertical versions have a separate console (shown left).

CSC - Split tube furnaces - 1200°C & 1700°C

These furnaces are ideal for processes requiring in-line heating for when rapid heating/cooling is essential.

Model CSC12 (shown left) - maximum operating temperature 1200°C. Heated by spiral wire coils embedded in ceramic fibre. Other heated lengths available on request.

Model CSC17 - maximum operating temperature 1700°C. Heated by molybdenum disilicide elements. Available as vertical model only.

An outer mesh guard on all models allows natural air cooling for maximum operator safety and comfort.

PTF - Three zone tube furnaces : 1200, 1500 & 1600°C

These units have a maximum operating temperature of 1200°C, 1500°C and 1600°C.

For units at 1200°C, heating is via an integral resistance wire element wound on to the ceramic work tube which is an integral part of the furnace. At 1500°C and 1600°C, silicon carbide rod elements are mounted parallel to the tube.

The end zone controllers are coupled to a centre zone thermocouple enabling the centre zone temperatures to be closely linked.
