Thermcraft XST Split Tube Furnaces

The Thermcraft XST Split Tube Furnaces have a hinged body which is split along its length. This design allows for easy process tube changes and simple installation of process tubes with end seals attached. These furnaces use Fibercraft™ vacuum formed ceramic fiber heating elements with free radiating wire embedded into the body of the heater. The tube adapters are removable and interchangeable so that multiple process tube sizes can be used with one furnace.

The SmartControl Standard Controller combines all the features of typical PID controllers, video/chart recorders, and datalogging systems into a single, intuitive device. The SmartControl provides a 4.3” color touch screen interface with standard, user configurable, runtime features for 1-10 zone control applications. All loop configuration and runtime user access is configurable at the device with no PC software required.
