Tube furnace up to 1350°C - FHA/FHC

Close

Език:

FHA 13/80/500 with control moduleFHA 13/80/500 with optional over temperature control, voltage/current display and high vacuum capable inert gas package. Rotary vane pumps and turbo pumps available as an option.

The FHA, single zone, and FHC, 3-zone, tube furnaces can be used either vertically or horizontally and have a maximum operating temperature of 1350 °C.

The extensive F range of tube furnaces is offered with a wide range of accessories. The furnaces comprise ceramic fibre modules with a high quality 5 mm APM wire heating element mounted in the insulation, held in position by a ceramic holding ridge. The low thermal mass ceramic fibre insulation ensures low energy consumption and allows fast heating rates. The control thermocouple is a high grade type S thermocouple. Additionally, the tube furnace is available with up to 8 heating zones for the most precise temperature control and uniformity.

Technical details

  5. 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.
