Crawler Ceramic Heater can also be used to customize the external heating sleeve for the reactor, as shown in the figure. The heating sleeve is composed of Crawler Ceramic Heater, insulating cotton and stainless steel shell from the inside to the outside. It is fixed into a whole through the shell and the reactor. It is characterized by fast heating speed, high thermal efficiency, and can directly control the temperature of the medium in the reactor. The control precision reaches ±1℃.
