Energy-saving fiber resistance furnace SD3-8-11 is introduced in detail

Performance characteristics of energy-saving fiber resistance furnace SD3-8-11:

■Large space, low power, energy saving and high efficiency

■High accuracy, the error is “0” at a high temperature of 1000 degrees

■Four sides heating, lining furnace bottom plate, integrated production, no need to install, it can be used when connected to the power supply.

■The control system adopts LTDE technology, with 30-band programmable function, and two-level over-temperature protection.

■The weight is 70% lighter than the traditional electric furnace, the appearance is small, the working room size is large, and the same external size is 50% larger than the traditional electric furnace working size

This energy-saving fiber resistance furnace (ceramic fiber muffle furnace) uses a ceramic fiber liner, high temperature heating wire to generate heat, energy saving and high efficiency. Three times the energy-saving fiber resistance furnace (speed adjustable). The integrated production solves the tedious preparation work of the original energy-saving fiber resistance furnace, installation, connection, and debugging. Just turn on the power to work. The control system adopts LTDE technology, automatic intelligent control, with 30-segment programming, curve heating, automatic constant temperature, automatic shutdown, and PID function to ensure the correct temperature of a certain point. It is an ideal high-temperature furnace for universities, research institutes, industrial and mining enterprises, and laboratories;
