Heating pipe heating water to produce steam heating, a special 304 stainless steel electric heating tube, long life. Using nickel-chromium heating wire material, built-in thermal insulating oxide nanomaterials, Nichrome wire and soldered terminals, which filled thermal insulating oxide nanomaterials. Heater power 72 kilowatts, divided into three groups individually controlled switches, retaining only one group after curing heat reaches the set temperature, this design can effectively save electricity consumption, reduce electricity costs sulfide. Hassle-free tank temperature uniformity, constant pressure. Solve the uneven temperature and pressure due to the product, and the product quality is not the same result. After setting procedures, automatic temperature control system, insulation, curing, etc., automatic power-off after curing concurrent sound and light alarm.
