ARF - Air recirculating chamber furnaces : 750°C

Both models in the ARF range have a chamber fitted with a robust stainless steel liner, enabling bulky loads to be treated. Optimum heat transfer, reduced heating times and maximum temperature uniformity are provided by a fan which ciruclates the air within the chamber. The fan and airguide system provide continuous movement of air around the workpiece.

Heating is provided by mineral insulated sheathed elements, which are fully isolated from the liner. A type 'K' thermocouple is incorporated for maximum life and stability.

This range of furnaces is particularly suitable for a wide range of low temperature heat treatment applications, such as:

- Stress relieving
- Melting low temperature alloys
- Thermal ageing
- Annealing
- Tempering

AF / SAF - Ashing furnaces : 1100°C

A choice of two models is available.

The AF 11/6 is an economy ashing furnace with a traditional muffle element. It meets the requirement for a low cost unit which will allow materials to be burnt rapidly at closely controlled temperatures.

The SAF 11/1 (shown left) is a more robust traditionally built muffle ashing furnace capable of accepting up to 15 crucibles up to 50mm diameter. A chimney is fitted on both models as standard.

EHF - Elevator Hearth (Bottom Loading) Furnaces - 1700°C & 1800°C

Lenton has developed a small range of elevator hearth furnaces for operation in air or inert gas atmospheres. The range is available with maximum operating temperatures of 1700°C and 1800°C with capacities of 3.4 and 7.9 litres.

Optimum temperature uniformity is obtained by the inclusion of molybdenum disilicide heating elements which are positioned around the walls of the chamber ensuring uniform heating of the sample. A combination of dense refractory brick hot face insulation and a secondary low thermal mass layer of insulation provides a robust chamber with an efficient utilisation of power.
