The inner tank adopts the 1.2 mm imported SUS304 stainless steel and automatic welding technology which decrease the corrosion. Inlet and outlet use the argon welding technology against the 0.8 Mpa pressure. Heatpipe tube conduct the heat energy in the single direction and has some advantages of the quick operation, high heat efficiency and anti-corrosion. It has some advantages of no water flowing in tube, no filthy, no broken tube, anti-freeze, unlimited time of the inputting water and pressure operation. Insulation adopts the polyurethane which has the even hole and good insulation efficiency. The frame adopts the imported SUS301 stainless steel, which is strong and against the corrosion. Tail stock has a novel design and is available to be installed.
