Operating Principle
KINTEK tube furnaces utilize high-quality heating elements (such as Cr2Al2Mo2 wire coil or SiC rods) to uniformly heat a process tube, typically made of high-purity alumina, positioned within an exceptionally insulated furnace chamber. A precision PID temperature controller continuously monitors the temperature of the process tube via a thermocouple and dynamically adjusts the power supplied to the heating element. This closed-loop system ensures highly stable and accurate temperature management, critical for processes like heat treating, annealing, sintering, and chemical vapor deposition.
