The furnace housing consists of a stainless steel construction and is placed on an underframe. The furnace is characterized by an operating friendly design.
The insulation exclusively consists of energy saving fiber material. A ceramic wool module with embedded heating coils respectively slotted SiC tube (1575°C) and corresponding end plates is used. Thin-walled, low heat storing materials enable extremely short heating up and cooling down cycles. Due to a circulating air layer between insulation and sheet metal housing, low outside wall temperatures are reached.
The furnace is heated with embedded Kanthal heating coils. They are fixed on the inner diameter of the heating tube and can optionally be switched in three zones. The heating elements are operated by transformers and electronic load relays/thyristor controller. This tube furnace disposes of a power reserve in order to be able to reach the desired temperature and control accuracy.
Each 1 PtRh-Pt thermocouple (accuracy: class 2 according to DIN IEC 584 part 2) respectively NiCr-Ni thermocouple (1150°C) is installed in the middle and in one of the outer heating zones and is led to the corresponding temperature controller. The thermocouples are inserted between two windings of the heating element and look into the useful chamber by app. 5 mm.
Switch and control unit
The switch and control unit with power part is installed in a separate housing and is connected with the tube furnace by flexible lines (1 to 1,5 mm). Among other things, the control unit is equipped with minimum one temperature controller G 400.
