The closed electric furnace is the heating equipment for laboratories of industrial and mining enterprises, hospitals, schools, scientific research institutes, agricultural environmental protection departments, etc. .

The closed electric furnace adopts imported energy adjustment switch. The furnace body is made of high-quality steel plate, and the furnace plate and heating wire mold are stamped, which can effectively increase the heat energy distribution and ensure the service life of the furnace plate. The power supply realizes the stepless speed regulation of the heating power, and the mechanical type adopts the short-circuit resistance wire to realize the extreme regulation of the heating. It is easy to operate, energy-saving, safe, and the life of the heating device is long, which is convenient for the use of various heating appliances.
No open flame contact, improving the safety of laboratory operators.
