Core Value: The Industrial Explosion-Proof Flanged Immersion Heater is engineered for critical safety in hazardous environments (Zone 1 and Zone 2) where flammable gases or vapors are present. Featuring a robust Ex d (Flameproof) Terminal Enclosure, this heater is designed to contain any internal explosion without igniting the surrounding atmosphere. Built to ASME standards with heavy-duty ANSI/DIN flanges, it provides reliable, high-capacity heating for the oil & gas, petrochemical, and chemical processing industries. BACKED BY 30 YEARS MANUFACTURING EXPERIENCE and UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS including hydrostatic pressure testing and insulation resistance verification. ✓ Explosion-Proof: Ex d IIB/IIC T1-T6 certified enclosure for maximum safety. ✓ Heavy-Duty Construction: ASME flanges (150# to 2500# rating) withstand high process pressures. ✓ High Power Capacity: Capable of multi-megawatt outputs for large tank and inline heating. ✓ Corrosion Resistant: Elements available in SS316, Incoloy 800/825, and Hastelloy. ✓ Precise Control: Integrated RTD/Thermocouple sensors for process and high-limit protection. ✓ Versatile Application: Ideal for heating crude oil, natural gas, hydrogen, and thermal fluids. ✓ Reliable Quality: 30 YEARS MANUFACTURING EXPERIENCE ensures welding integrity. ✓ Quality Assured: UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS. ✓ Global Standards: CE, ATEX, IECEx, PED, ASME compliant.

For immersion lengths over 1000mm, internal tank supports (baffles) are required to support the element weight and prevent vibration damage. Cable Glands: MUST use certified Ex d cable glands or stopping boxes to maintain the explosion-proof integrity of the enclosure. Temperature Control: A safety control loop is mandatory. The high-limit sensor (attached to the heating element) must trip the power contactor directly to prevent overheating in case of low liquid level. Cold Zone: We design the “Cold Zone” length (unheated section) to ensure the terminal box does not overheat due to heat conduction from the process fluid.
