HT – Graphite – Series

HT – Graphite – Series

The Linn High Temp – HT – Graphite – Series is a gastight cold-wall modular furnace system engineered for fast cycles in controlled atmospheres, delivering high-temperature performance with exceptional reliability. Designed with a double stainless-steel housing for corrosion protection, the furnace features rigid graphite board back insulation combined with ceramic fiber boards to ensure excellent thermal efficiency.

Heating is achieved through U-shaped heaters made from extruded graphite rods, securely suspended from the oven roof for uniform heat distribution. Temperature is precisely monitored using a Type C (W/Re) thermocouple, housed in a molybdenum protection tube, capable of withstanding the extreme conditions of HT 1900 models. With the ability to reach 1400 °C in less than one hour, the HT Series offers a good space-to-useful volume ratio and includes a standard safety controller, making it an ideal choice for advanced laboratory and production applications requiring high precision and durability.
