Carbolite HTRV-A Split Tube Furnaces (up to 1700°C)


The Carbolite HTRV-A Split Tube Furnaces (up to 1700°C) have a maximum operating temperature of 1700 °C.

The split heating module allows either easy positioning of the work tube or positioning around reactors which have fixed end flanges. The split design may also allow faster cooling of samples. The control thermocouple is fitted in the centre of the heating zone. Cooling channels are engineered into the housing to aid with convection cooling of the outer case.

The two furnace chamber halves consist of high grade insulation plates with vertically hanging MoSi2 heating elements. A safety switch protects the operator by switching off the heating elements once the furnace is opened.

The tube furnace is supplied without a stand, allowing customers to build them into their own equipment. Optional "L" stands are available allowing the furnaces to be self supporting.
