The integrated programmable high-temperature furnace, also known as the integrated programmable box-type electric furnace or integrated programmed muffle furnace, features a ceramic fiber inner chamber and high-temperature heating wires for energy efficiency and high performance. Its energy consumption is only one-third that of ordinary high-temperature furnaces, with rapid heating capability. The outer shell is made of cold-rolled steel with spray coating, offering a lightweight design and weighing only one-fifth of conventional high-temperature furnaces.

The control system utilizes a fully automatic multi-band LTDE programmable instrument with adjustable heating rates. The PID + SSR system ensures synchronous and coordinated control, enabling consistency and reproducibility for any test or experiment. It includes automatic constant temperature and time control functions, along with secondary over-temperature protection for reliable and safe operation. The control instrument is located below the chamber, integrated into the unit. Electrical connections between the furnace body and temperature controller are completed before shipment, allowing for immediate use upon power connection. It is an ideal high-temperature furnace for universities, research institutions, industrial and mining enterprises, and laboratories.
