HT top loading furnaces are perfectly suited for the heat treatment of longer or heavier components. The pit type furnace is usually charged with a factory crane. Due to their high-performance air circulation, the pit furnaces provide for excellent temperature uniformity up to a maximum temperature of 850 °C. The top-loading furnaces for the temperature range up to 1280 °C provide for very good temperature uniformity due to their five-side heating. Alternatively, these Top-loading furnaces can also be provided with gas heating. Customized dimensions are designed and produced to accomodate the size and weight of the components to be treated.

Tmax top loading furnace can up to 850 °C for furnaces with air circulation.

Tmax up to 1280 °C for furnaces with radiation heating

Electrically heated or gas-fired

Heating from both long sides for furnaces with air circulation

Heating from all four sides and the bottom with SiC plates in the bottom of pit type furnace as level stacking support for models to 900 °C or 1280 °C

Depending on the pit furnace model, manual or electrohydraulic opening system of the lid with two-hand operation

Closable air supply vents in the lower area of the top-loading furnace chamber

Closable exhaust air flaps in the lid

Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the top load furnace and load

Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumina silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
