The furnaces are constructed of aesthetic welded steel structures, low heat capacity ceramic fiber and lightweight brick masonry. The quality of the masonry depends on the temperature. The trolley version can be operated manually, in the front. Manually operated door that can be opened on two points. Automatic firing system equipped with high speed burners. The equipments are suitable for operation by natural gas or LPG. Programmed firing control, automatic neutral or furnace atmosphere reduction control. The furnaces of the furnace family have a masonry built of light fiber insulating material and as a result of this the weight of masonry is less than that of classical masonry. For this reason the furnaces have: - Short heating time - Excellent thermal insulation - Lightweight equipment - Low specific energy consumption (especially in case of intermittent operation) In case of the tiltable version, the furnaces are tilted first around the pouring lip, allowing the molten metal to flow out on the same position. Continuous, smooth casting is ensured by the easily and well controllable hydraulic cylinders. Electric furnaces are heated by heating panels made of polygonal elements. The panels are assembled as heating blocks so that they can easily be replaced if needed after lifting the furnace lid. In the case of stationary furnaces, it can be replaced without removing the crucible. Electric furnaces are heated by heating panels made of polygonal elements.

Aluminium transporting, pouring trolley: The aluminum transporting pouring trolley is suitable for the secure transport of molten aluminium between the aluminium melting furnaces and the cooling furnaces within the plant. It can be used for pouring as well. The two wheels with brakes ensure that the trolley cannot move during loading and unloading. The manually operated hydraulics enable an easy and controlled cauldron tilting.
