The advanced FRV/FRH Series air furnaces from Linn High Temp are high-precision tube furnaces designed for laboratory use, offering excellent temperature uniformity and rapid heat-up cycles. Suitable for vertical (FRV) or horizontal (FRH) operation, these gastight furnaces support long-term operation at 1250 °C, with a maximum temperature of 1300 °C.
High-performance insulation is achieved through vacuum-formed ceramic fibre shells, while heating is provided by spiraled FeCrAl wire heaters embedded in the insulation. Temperature is measured with high accuracy using a Type S (PtRh/Pt) thermocouple. The series supports tube diameters from 40–100 mm with heated lengths of 250–520 mm, and 3-zone models range from 40–150 mm in diameter with heated lengths from 750–1000 mm.
