The explosion-proof flanged immersion heater is specifically designed for safe and efficient heating in hazardous environments where flammable gases, vapors, or liquids may be present.
It integrates a robust flange connection with explosion-proof junction housing, ensuring secure installation and reliable electrical insulation.
When current passes through the resistance wire, the generated heat is conducted through high-purity magnesium oxide insulation powder to the metal sheath surface, then transferred efficiently to the medium—such as water, oil, or chemical solutions.
Constructed with high-quality stainless steel, copper, or nickel–iron–chromium alloy sheath, the heater provides excellent corrosion resistance and long-term durability even under harsh industrial conditions.
This design ensures stable performance, quick heat transfer, and enhanced safety protection, making it ideal for industrial tanks, pipelines, and fluid heating systems in explosive environments.
