HST, HZS – Horizontal Split Tube Furnaces

Description

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 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, for example, 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 HZS offers excellent uniformity which results from division of the heated length into 3-zones each with its own controller and thermocouple.

  Standard features
•  1200°C maximum operating temperature

•  Carbolite Gero 301 digital PID controller with single ramp to setpoint, digital display and process timer
•  Furnace splits into two halves to accommodate work tubes or samples fixed into a test rig
•  Heated lengths, single zone 200, 300, 400, 450, 600 or 900 mm
•  Heated lengths, 3-zone 600 or 900 mm
•  Horizontal furnace with a separate control module on a 2 metre conduit
•  HZS: End zone control is via back to back thermocouples
