Industrial Machinery Applications & OEM Integration
Global Industrial Heaters engineers custom Industrial Immersion Heaters tailored for heavy-duty process machinery, factories, and OEM equipment:
Industrial Storage Tanks & Boilers
Heavy-duty flanged bundles (15kW to 250kW) for feed water preheating, steam boilers, calorifiers, and municipal water treatment heating vats.
Fuel Oil & Bitumen Heating
Low watt-density designs (1.2–2.0 W/cm²) prevent carbonization in heavy fuel oil (HFO), bunker C oil, lube oil reserves, and asphalt storage tanks.
Chemical Processing & CIP Vats
Corrosion-resistant SS316L, Incoloy 825, and Hastelloy bundles for caustic soda tanks, clean-in-place (CIP) wash systems, and acid solutions.
