SERN 4.5kW 380V Triangle Reverse Flange Heavy Industrial Immersion Heating Element CR304 Stainless Steel Water Heater
The SERN 4.5kW heavy industrial immersion heating element is engineered with high-grade manufacturing standards for commercial boilers, industrial water processing tanks, steam generators, and heavy-duty heating vessels. Operating on 380V three-phase electrical supplies, it delivers high-efficiency thermal output for rapid fluid temperature elevation and continuous heat maintenance in demanding commercial operations. Constructed from premium CR304 (Grade 304) food-safe stainless steel, this element demonstrates exceptional resistance to high mineral content, hard water scale, and thermal stress under continuous submersion. Equipped with a heavy-duty triangular reverse flange, it provides a pressure-tight, leak-proof mechanical fitment designed specifically for high-capacity industrial tank configurations.
Technical Specifications: Brand: SERN Product Type: Heavy Industrial Reverse Flange Immersion Element Power Rating: 4.5 kW (4500W) Operating Voltage: 380V (Three-Phase) Flange Type: Heavy-Duty Triangle Reverse Flange (Üçgen Ters Flanş) Body Material: CR304 Grade Stainless Steel (Food Grade) Terminal Connection: Heavy-Duty Threaded Electrical Terminals with Brass Hardware Applications: Commercial steam boilers, industrial liquid storage tanks, brewing vessels, heat exchangers, and heavy-duty calorifiers
Advantages: Built with genuine SERN quality engineering for maximum industrial endurance and continuous heavy-duty operation. High 4.5kW thermal capacity ensures fast pre-heating and rapid fluid temperature recovery in large volumes. Triangular reverse flange design guarantees secure, vibration-free, and leak-proof mounting against industrial tank cutouts. Premium CR304 stainless steel sheath resists lime-scale build-up, pitting, and long-term water corrosion. Engineered for reliable 380V three-phase power distribution, optimizing current draw across electrical phases. Heavy-duty terminal construction protects electrical connection points against high thermal degradation.
Disadvantages: Flange bolt hole dimensions, pitch circle diameter, and internal vessel immersion depth must be verified prior to fitting. Designed strictly for liquid immersion; running the element dry without fluid coverage will cause immediate thermal failure. High-voltage 380V three-phase installation must be conducted by a certified industrial electrician.
