FHA (Zone 1) and FHC (Zone 3) are tube furnaces that can operate at a maximum temperature of 1350°C and can be used both horizontally and vertically.
The F series has a wide range of applications and is equipped with a rich variety of accessories. It features a high-quality 5mm APM wire heating element embedded in insulation, held in place by a ceramic ridge. The low heat capacity insulation made of ceramic fiber enables reduced energy consumption and improved heating rates. The control thermocouple is of high-grade type S. Additionally, when precise temperature control and uniformity are required, the heating area can be subdivided into up to eight zones.
