The system is supported by a single frame platform which supports the furnace and electronic cabinet containing the software controls. Casters are attached to the supporting platform, which allows the whole system to move easily. For universities and industrial research laboratories, the LHT series is a perfect fit for such operating areas.
The small overall dimensions and simple operation result in a cost effective system without any performance loss in temperature uniformity or atmospheric quality. Additionally, the cylindrical design is best suited for overpressure heat treatment processes. Upon request, the system can be equipped with a suitable locking device and all necessary equipment for safe overpressure operations up to 100 bar.
The LHTG has heating elements and insulation material made from graphite. Graphite based LHT models are temperature controlled by pyrometers. An over-temperature thermocouple can be added as an option, which is highly recommended for unattended operation. Under Argon environment, the maximum temperature is 3000 °C, which requires the use of a pyrometer to measure the chamber temperature. The pyrometer is combined with the use of a sliding thermocouple to measure temperatures at the beginning of the process as the initial temperatures are not high enough to be detected by the pyrometer.
