Outer Coil Heating Tank is an all-in-one industrial vessel designed for heating, insulating and storing liquid and paste materials. It adopts an external heating coil structure, using steam, thermal oil or hot water as the heating medium. The tank is made of food-grade and corrosion-resistant SUS304 or SUS316L stainless steel, with features of uniform heating, precise temperature control, easy cleaning and low energy consumption. It is widely used in food, pharmaceutical, cosmetic, chemical, coating and grease industries.
