Technical details

Furnace housing

The furnace housing as well as the door consists of a mild steel construction. As protection against corrosion the furnace parts are powder coated.

The chosen colours give a nice appearance to the whole furnace. The door is designed as a swivelling door and is mechanically linked with the furnace housing.

Insulation

The fibre insulation is made from a block of high purity alumina fibre using the vacuum-drawing process, followed by pre-sintered fibre insulation boards.

Due to the fibre insulation materials high thermal power at low energy consumption is achieved. This also results in a low furnace weight.

Heating

The surface of the SIC muffle is wired with heating spirals, providing a constant temperature distribution inside the chamber. In connection with the insulation extremely short heating up - and cooling down cycles at low heating power will be obtained.

Control unit

The control system is installed in the lower furnace part. It is equipped with the following components:

- safety controller for overtemperature switch off

- temperature controller with a pre-set heating ramp (Eurotherm 3216)

- switch for heating

- main switch

- controlling thermocouple 2xNiCrSi-NiSi (type “N”)

- for 1280°C version: controlling thermocouple 2xPt13Rh-Pt (type “R”)

- electronic load relay

- door limit switch for cutting power to heating element while door is in open condition.
