Stainless steel heating tubes offer a long service life, with a general design life exceeding 10,000 hours, making them durable and practical. 4. The product is equipped with a silicone sealing gasket that is elastic, waterproof, firm, and stable. 5. Suitable for electric water boilers, kitchen equipment, industrial cleaning equipment, commercial air conditioners, drinking water equipment, solar energy systems, electric fryers, and similar appliances. Specification: 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 Note: 1. 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 approximately 200°C for several hours (or energized under low voltage for several hours) to restore insulation resistance. 2. If carbon buildup is observed on the tube surface, it must be removed before use to avoid reduced efficiency or potential damage to the component. 3. When melting bitumen, paraffin, or other solid oils, operate at reduced voltage initially, then increase to rated voltage after melting is complete, to prevent power concentration and extend component life.
