Technical details

Furnace housing

The furnace housing consists of a lightweight steel construction. As protection against corrosion they are coated with a special lacquer. The chosen colors blue/white give a nice appearance to the entire furnace.

Insulation

Ceiling, heated side walls, rear wall and bottom are covered with high quality lightweight refractory bricks. By using these bricks the burning goods will not be contaminated by broken insulation material falling down.

The additional heat insulation with calcium silicate boards ensures a high thermal capacity at low energy consumption. The door is lined with fiber modules.

Heating

Heating is effected by free radiating Kanthal A1 bzw. APM heating spirals (hair pins) in rills of the bricks of the side walls, the rear side and the bottom. The furnace bottom is covered with a well thermal conductive ceramic plate. For the activation of the waste of the burning materials and the cooling behavior during cooling phase, air channels are installed in the furnace bottom through which fresh air with well chamber distribution will be guided to the top side due to thermal lifting.

Control unit

Connection field and power electronic are tightly installed at the furnace rear side. The controller G800 is placed in a separate housing which is connected to the furnace and is assembled at the side wall of the furnace system:

2 or 3 setpoint controller with PID behaviour
Logic output and continuous output
Max. 4 programs with max. 16 segments / steps programmable
Display of actual and desired value
Self-optimization prevents overshooting
Separation of control and configuration level (prevents undesired changes)
4 switchable parameter sets
Alarm signal in case of thermocouple fracture
Serial interface

A safety switch is installed on the furnace which switches off the heating during opening the door by a constraint disconnection. The furnace is provided with a connection cord.
