Furnace (High Temp.)

This furnace model is technically designed with the most advanced types of insulating fibres and heating elements to obtain a very high-temperature range in a much shorter time than other furnaces in the market built with conventional refractory bricks. It is also perfectly thermally insulated, with no significant inertias. The chamber is internally built entirely with ceramic fibre. Above this volume, the bottom is manufactured with high-temperature refractory bricks of very high aluminium content and melting point, enabling a load of heavy crucibles, samples or objects with no risk of sinking or breakage. The chamber top and sides’ fibre plates are supported by and attached to a double layer of ceramic refractory plates of the same type as the bottom plate described above. End-user-friendly readily replaceable heating elements on the sides of the work chamber.
