inner insulation (hot face)
The rectangular housing is constructed with slots for convection cooling of the outer housing. With insulation made from low thermal mass ceramic fibre material,the heat conduction is reduced to a minimum.
Inside the tube furnace,the heating element is constructed of vacuum formed fibres containing free radiating heating elements that are attached to the insulation by a ceramic holding ridge.
When compared to conventional heating methods,the 5 mm thick heating wires are combined with a low voltage,heavy-weight transformer power supply that provides an extraordinary long lifetime of the heating elements and temperature stability. The control thermocouple is a high grade type S thermocouple. Additionally,each tube furnace model is available with up to 8 heating zones for the most precise temperature control and uniformity.
