Item Type: Heating Tube Material: Stainless steel, brass, silicone Uses: Widely used in various heating applications Working Voltage: AC 220/380V Package List: 1 x Heating Tube 1 x Protection Cover The components should be stored in a dry environment. If the insulation resistance drops below 1 megohm due to long-term storage, they can be dried in an oven at about 200C for several hours (or exposed to low pressure for several hours) to restore the insulation resistance. When carbon buildup is found on the surface of the tube, it must be removed before use to maintain efficiency and prevent damage. When melting bitumen, paraffin, and other solid oils, the voltage should be reduced initially and then increased to the rated voltage after melting to prevent power concentration and extend component life. The product has a simple structure, high mechanical strength, high thermal efficiency, safety, reliability, easy installation, and long service life. It is used in various devices such as saltpeter tanks, water tanks, oil tanks, acid-base tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, and hot press molds. The service life of stainless steel heating tubes is long, with a general design life of over 10,000 hours, making them durable and practical. The product is equipped with a silicone sealing gasket, which is elastic, waterproof, firm, and stable. Suitable for electric water boilers, kitchen equipment, industrial cleaning equipment, commercial air conditioners, drinking water equipment, solar energy equipment, and electric fryers.
