These furnaces are manufactured in two halves and are hinged together for easy loading of a reactor vessel or worktube, or large workpiece. The design offers the flexibility to place the furnace around a fixed item - such as a pipe with flanges which are too large to pass through a solid tube furnace, or around a sample which is fixed into a materials test rig.
The HST models are ideally suited for horizontal, bench use, whilst the VST models have the same maximum internal diameter, but smaller external dimensions and are primarily designed to fit within test rigs. The VST models can also be mounted on a stand with either near or far hinge, or wall mounted with a bracket.
Three zone versions of the split furnace are also available for improved uniform length with three zone control.
