The Linn High Temp – FRV/FRH Series (Vertical and Horizontal models) is a gastight tube furnace designed for operation under controlled atmospheres, offering high heating power and excellent temperature uniformity for fast thermal cycling. Suitable for temperatures up to 1550 °C, the furnace is available in multiple versions rated for 1200 °C, 1300 °C, and 1600 °C. It features durable vacuum-formed ceramic fibre insulation in the form of half shells or cylinders, with FeCrAl wire spiral heaters embedded within the insulation for efficient and uniform heating.
Temperature is precisely measured using Type S (PtRh/Pt) or Type K/J (NiCr/Ni) thermocouples, depending on the temperature range and application. The FRV/FRH Series is offered in a range of sizes, with tube diameters from 40 mm to 100 mm and heated lengths from 250 mm to 520 mm, as well as 3-zone models for enhanced control, available in 40 mm to 150 mm diameter with heated lengths of 750 mm to 1000 mm. This versatile and compact furnace is ideal for laboratory and small-scale production processes requiring controlled atmospheres and high-precision thermal management.
