Tube Furnace KTF 1100°C Series (3 Zone Control)

3-zone controlling high-accuracy electrical furnaces for experiments and laboratory researches
Tube Furnace KTF 1100°C Series (3 Zone Control)

Maximum temperature
1100°C

Feature

  • Cylindrical Moldatherm heaters (*) for a little heat loss.
  • 3 zones are separately controlled for highly accurate furnace internal temperature control.
  • An overheating preventing meter is installed at the center only as standard equipment.
* Moldatherm heater: Heater equipped with thermal insulator. Our original heater is made by integrating ceramic fiber and a wavy heating element (LGO) into a solid structure using our unique vacuum forming method. Moldatherm heaters are also used for the heaters made by our company for the production use semiconductor devices and metal heat treatment systems.
Applications R&D, Firing
Option Process tube (Metallic tube, Quartz tube, Ceramics tube),
Gas supply system, Temperature Programmer,
Temperature Recorder , Over-heat Protection

The compact, energy-saving, electrical furnaces (tube furnaces) control 3 zones separately to achieve high accuracies. The furnaces use cylindrical tubes for a little heat loss, and Moldatherm heaters for raising and lowering temperature at high speeds. Quartz tubes that do not generate particles can be optionally installed for high-quality experiments. Overheating preventing meters (at the center zones) and limit switches are installed as standard equipment for safety.

(*1) Temperature at the control point within the heating chamber. No empty furnace and tube.
(*2) Temperature at the control point within the heating chamber when a tube is installed.
(*3) The temperature at the control point does not meet the temperatures at temperature distribution measuring points.
Temperature accuracies in the table are determined by shifting temperature settings.
☆ The maximum working temperature varies depending on the optional equipment and conditions of operation.
☆ Thermocouples are consumable items.
