Product Description

The NACHZS 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.

Excellent uniformity results from division of the heated length into 3-zones each with its own controller and thermocouple. 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. A vertical equivalent of the NACHZS range, the NACTVS range is available.
