Chamber furnaces of type HTK KE furnaces are insulated with ceramic fibre. The rectangular design with a front door allows for easy loading and unloading. The HTK range is available in up to six different sizes. The smallest designs with a capacity of 8 litres and 25 litres are typically employed by laboratories for research and development. The 80 litre, 220 litre, 400 litre or 600 litre furnaces are predominantly used as pilot manufacturing systems or large scale production. The furnaces can be used under a defined Oxygen mixture or 100 % pure Oxygen. The heating elements are CrFeAl, allowing temperatures of up to 1350 °C, or MoSi2 that allow temperatures up to 1800 °C. Inert gas atmospheres are possible, however, poor atmospheric quality must be accepted. Due to the porous nature of the insulation, vacuum operation is limited to a rough vacuum range for short durations. Application Examples ceramic injection moulding (CIM), debinding in air, sintering in air Standard features Hydrogen partial pressure operation if requested Operation under air or with 100 % Oxygen in the HTK KE Precisely controlled vacuum pumping speeds appropriate for powders Data recording for quality management
