This furnace is now obsolete. The nearest replacement model is the TF3 16/100/600.
Carbolite TZF 15/610 High Temperature Three Zone Tube Furnace, heated length 610mm.
The maximum temperature of the TZF 15/610 is 1500°C, with a continuous operating temperature of 1400°C. Heat up time: 75 minutes. Uniform length is 450 mm plus or minus 5°c. Maximum power consumption is 8000 watts. Each zone has its own controller and thermocouple. For the end zones, two 3216CC are supplied, and for the centre zone, the 3216P1 controller. Complete with re-transmission of the set point.
Silicon Carbide elements allow fast heating to operating temperature. Furnaces do not include a work tube; customer may have their own or choose from chemically resistant tubes or other lengths, depending on the application. Furnaces can be bored to accept a specific diameter, as standard accepts 90mm outer diameter. Longer tubes allow clearance from the furnace to support accessories necessary for gas insertion and vacuum deployment: work tube seals, plugs, gas or vacuum inlets.
The TZF heated length is divided into three zones. In a standard single-zone tube furnace, uniformity drifts towards the tube ends. On the TZF range, the uniform zone in the mid-section of the work tube is extended using end-zone controllers that track the centre-zone temperature and compensate for heat loss at the ends of the tube. These three control systems balance the power to the heating elements.
Features
- Excellent uniformity.
- The furnace can be mounted vertically using an L stand, with the controller in a separate control box.
- Option Over-temperature protection is used if the furnace contains expensive contents or is left unattended for long periods.
- A range of additional work tubes in various lengths and materials, quartz, ceramic, metal, end seals and work tube packages is available for use with modified atmosphere and vacuum. Or for simply aiding heat retention.
- Pumps for vacuum applications include rotary vane pumps and turbomolecular pumps.
- Accessories: Insulation plugs & radiation shields to contain heat loss and enhance uniformity.
- Hook and strap work tube support.
- Electrical configuration: 2 or 3 phase electrical supply possible.
