Due to their high-grade insulation and optimized connected loads the models T and TF can be used both for melting and holding. They feature good melting output together with outstanding temperature uniformity in the melt. The 1100 °C version can be used for melting aluminum, the 1200 °C version for brass as well. The 1300 °C version can also be used for melting bronze alloys.

The T models are fitted with multi-layer insulation. The furnace chamber insulation with high-quality lightweight refractory bricks is recommended for holding operation. For rapid heat-up times in non-continuous operation, the TF models can also be used, which are lined with a fiber insulation with low heat retention capacity.

  • T, TF../11 with maximum furnace chamber temperature of 1100 °C for aluminum or zinc. Maximum melt temperatures, depending on the condition of the crucible, between 950 °C and 980 °C
  • T, TF../12 with maximum furnace chamber temperature of 1200 °C also suitable for brass. Maximum melt temperatures, depending on the condition of the crucible, between 1050 °C and 1100 °C
  • T, TF../13 with maximum furnace chamber temperature of 1300 °C, also suitable for bronze alloys. Maximum melt temperatures, depending on the condition of the crucible, between 1150 °C and 1200 °C
  • Four-side heating using electric heating elements, freely radiating on carrier tubes
  • Simple replacement of individual heating elements. In case of crucible breakage, only the defective heating elements on each level need to be replaced
  • Heating of furnaces up to 60 kW power rating controlled using long-lasting, noiseless solid-state-relays
  • Heating of furnaces beyond 60 kW with contactors
  • High melting performance with temperature uniformity in the melt
  • Insulation constructed in multiple layers with lightweight refractory bricks on the hot face (T models)
  • Insulation constructed in multiple layers with fiber material in the side walls and corner bricks to support heating elements (TF models)
  • Emergency outlet for safe draining of the melt in case of crucible breakage
  • No exhaust gas discharge needed
  • Integrated safety system which continues to operate the furnace at reduced power in case of malfunction in the bath thermocouple, in order to prevent the freezing of the melt
  • Over-temperature limiter in furnace chamber for protection against overheating. The limiter switches the heating off when the set limit temperature is reached, and only switches it back on after the temperature has fallen again
  • Furnace chamber control with temperature measurement behind the crucible, recommended for melting
  • Crucible not included in the standard version

Additional equipment

  • Crucible of clay-graphite or SiC
  • Work platform
  • Crucible breakage monitor with visual and audible signal (not for 1300 °C models
  • SMS-message to one or more mobile phones in case of crucible breakage. One or more furnaces can be connected to the messaging device in parallel
  • Bath control with thermocouples in the furnace chamber and in the melt (not for 1300 °C models). The furnace temperature is controlled through the melt. Temperature overshoots are reduced, thus the quality of the melt is improved
  • Heating system operated through thyristors in phase-angle mode assures an even charging of heating elements
  • Multi-step switching of the furnace heat (see page 23). In holding mode, a switch or the controller is used to turn off one heating section in order to reduce the electrical rating
  • Higher electrical ratings to increase melting performance
