Product Description

The NACTVS tube furnaces use free radiating wire elements embedded within the insulation of the furnace body. The benefit of this design is its flexibility; with the use of tube adapters the same furnace can be used with a variety of tube diameters.

These furnaces comprise a furnace body which is hinged and split into two halves along its length. This makes exchange of work tubes easier and also enables the furnace to be used with reactors or work tubes where end flanges would make insertion into a non-split furnace difficult. This design is particularly suitable for incorporation into extension test and creep test apparatus.

This range of tube furnaces does not include an integral work tube and one must be selected as an additional item. The work tube length is dependent on the application eg for use with modified atmosphere or vacuum.

The use of a separate work tube has the advantage of protecting the heating elements from damage or contamination. The ‘near-hinge’ format is standard, an alternative option that can be specified at the time of purchase is the ‘far-hinge’ format, where the pivot of hinges is further from the centre line of the furnace to enable a wider opening action. A horizontal equivalent of the NACTVS range, the NACHZS range is available.
