Series 3410/3420 Tube and split tube furnaces incorporate silicon carbide type heating elements have slow aging characteristics, high density, increased strength, and ease of replacement. These furnaces are useful for processes that involve many materials and can reach temperatures of 1540°C. Features: Stainless Steel Shell and end flanges Silicon carbide (SiC) heating elements Temperature ratings up to 1540°C (2800°F) Dependable, steady heat up Low K-factor vacuum cast ceramic fiber insulation Build-to-Order Custom zone arrangement Accessories: Extensometer mounting flats Extensometer slots Thermocouples Viewports Temperature control systems Gas-tight retorts Additional options available!

Series 3450 Furnaces are the box counterparts to the 3410/3420 series, incorporating the same silicon carbide type heating elements, slow aging characteristics, high density, increased strength, and ease of replacement. Heating elements are spiral-cut “bayonet” type silicon carbide, oriented in either a vertical or horizontal configuration. Features Stainless Steel Shell Silicon carbide (SiC) heating elements Temperature ratings up to 1540°C (2800°F) Dependable, steady heat up Heating elements are spiral-cut type silicon carbide (vertical or horizontal configuration) Low K-factor vacuum cast ceramic fiber insulation Full-opening front door Build-to-Order Custom zone arrangement Accessories: Load train ports Thermocouples Viewports Muffles Liners Gas ports Temperature control systems Additional options available!
