Pit-Type and Top-Loading Furnaces up to 1400 °C

Our top-loading furnaces are perfectly suited for firing, sintering or tempering of long, heavy products. Charging is mostly carried out with the help of an overhead crane. Heating from all sides and from the bottom provides for an good temperature uniformity. Tailor-made dimensions are designed and manufactured in accordance with the size and weight of components.

• Tmax 900 °C, 1280 °C, 1340 °C or 1400 °C
• Five-side heating from the sides and the bottom
• Heating elements on supporting tubes provide for long service life
• SiC-bottom plates provide for level stack charging surface
• Bottom heating protected by SiC plates
• Multiple layer insulation with lightweight refractory bricks and special backing isolation
• Lid insulation consists of fiber material with a special fastening
• Electrohydraulic opening system of the lid with two-hand operation
• Closable air supply vents in the lower area of the furnace chamber
• Closable exhaust air vents in the lid
• Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load

Additional equipment
