Bell-type furnace is a furnace type of that furnace body moves from a fixed bottom to up. Its base remains stationary. The furnace body moves up and down. This movement is provided with railed sledges.
Bell-type furnace provides ideal conditions for the heat treatment of stack samples (nut, bolt, etc.).
The products are placed in specially designed baskets according to process which is inside of the bell-type furnace. Fan system and environmental placed resistances provide a more homogeneous heat distribution in the furnace. Then, cylindrical retort closes and gas sweeping and vacuuming is done. (Retorts are preferred according to process type. It may not use in every bell-type furnace.)*

thanks to double-layers steel construction
Epoxy painted galvanized-steel exterior
Height adjustable, non-slip rubber feet.
(DL) Data logger
(PCC) PC Communication and Software
- (PLC) PLC control and touch screen
- Can be placed of small and stack samples
- Homogeneous heating with a circulation fan and resistances placed on four side
- Takes smaller space than the tunnel furnaces
For the maximum life of the furnace and the longer use of the furnace equipment, we recommend that the heating rate of 10 °C/min should not exceeded. Flammable and explosive products must not be used in the furnace. Oily products mustn’t be put in the furnaces.
The features which are signed with a star (*) may get change or not available according to the change on process necessity, volume, temperature and furnace model.
Bell-type furnaces are specially manufactured according to the requested capacity up to 1800 °C continuous usage temperature.
