HT – 1900 – Vac – Series

The HT–1900–Vac–Series by Linn High Temp features vacuum-tight cold-wall modular furnaces engineered for fast thermal cycles. With a compact double stainless-steel housing, these furnaces offer an excellent balance between space efficiency and usable volume, while also providing robust corrosion protection. Designed with user safety in mind, a standard safety controller is included. These furnaces can reach temperatures of up to 1400°C in under one hour. The HT Vac Series comes equipped with a gas feeding device for vacuum operations and a vacuum pumping station with integrated vacuum measurement capabilities. Heating is provided by U-shaped heaters made from extruded graphite rods, suspended from the furnace roof. Temperature is precisely monitored using a Type C (W/Re) thermocouple housed in a molybdenum protection tube.
