Chromalox ARMTI-3455E2 Immersion Tank Heaters

Powered by 480 VAC, the Chromalox ARMTI-3455E2 immersion tank heater delivers 4.5 kW of heating in a compact screw-plug design for reliable in-tank heating of process liquids. The model uses Chromalox’s explosion-resistant E2 terminal housing, providing enhanced protection in hazardous-location installations, and carries PCN 156-500535-544 for ordering accuracy. This immersion heater is designed to be screwed into a tank opening, delivering heat directly into the liquid to promote consistent temperatures, reduce viscosity, or prevent crystallization in industrial processes. The ARMTI family is intended for applications where a compact, field-terminable heating element is required, with a 480 VAC electrical supply and a 4.5 kW heat output suitable for mid- to high-heat process zones. Intended uses span process liquids in industries such as chemical processing, oil and gas, and wastewater treatment, where tight temperature control in a closed tank is essential. When selecting this model, ensure compatibility with your tank opening, electrical supply, and local hazardous-location codes to meet installation requirements.
