This furnace is now obsolete. The nearest replacement model is the TF3 16/100/450.
Carbolite TZF 15/450 High Temperature Three Zone Tube Furnace, heated length 450mm.
The maximum temperature is 1500°C, with a continuous operating temperature of 1400°C. Uniform length is 375 mm plus or minus 5°C. Maximum power consumption is 5060 watts. Each zone has its own controller and thermocouple. For the end zones, two 3216CC controllers are supplied, and for the centre zone, the 3216P1 controller. Complete with re-transmission of the set point.
Silicon Carbide elements allow rapid heating to operating temperature. Furnaces do not include a work tube; you can use your 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 has valuable contents or is left unattended for extended 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 merely 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 strapwork tube support.
- Electrical configuration 2 or 3 phase electrical supply possible – specify on order.
