Chemical & Acid-Resistant Immersion Heaters

Chemical & Acid-Resistant Immersion Heaters

Chemical and acid-resistant immersion heaters are selected for process liquids whose chemistry may attack conventional metal sheaths or mounting components. Depending on the chemical, concentration, temperature, and process conditions, suitable constructions may use corrosion-resistant alloys, fluoropolymer-coated components, ceramic materials, or other specialised wetted materials. No single heater material is compatible with every chemical: concentration, contaminants, temperature, exposure duration, and mechanical abrasion can change corrosion performance significantly. For this reason, the exact chemical name and concentration must be reviewed before a material is recommended. The heater arrangement may be flanged, screw plug, over-the-side, or custom-built to suit the tank. The design should also account for vapours, ventilation, tank lining, immersion depth, and electrical protection. Correct chemical compatibility and appropriately controlled surface loading are central to safe and reliable service.
