Production description
In applications that need a lot of chemical processing, electroplating, pickling, and treating wastewater, reliable heating is very important. Our 380V PTFE Immersion Acid Resistant Tubular Heating Elements for Chemical Environments work far better than regular heaters in chemical environments. These immersion heaters are made with high-quality stainless steel tubular cores that are completely covered in high-purity PTFE (Polytetrafluoroethylene). They are very resistant to corrosion from strong acids (like sulphuric, hydrochloric, nitric, and hydrofluoric acids under controlled conditions), alkalis, and other harsh chemicals.
These immersion heaters are safe to use in solutions with a pH range of 0 to 13 and temperatures up to 100°C (212°F). They won't leak, scale, or break down. The PTFE surface that doesn't attach to anything keeps buildup to a minimum, which keeps heat transfer consistent and extends the life of the device. Our acid-resistant tubular heating elements are great for chemical tanks, plating baths, anodising lines, and heating corrosive liquids in factories. They help keep process temperatures stable while cutting down on downtime and maintenance expenses.
What Are the Benefits of Our PTFE Tubular Immersion Heaters?
Heavy-wall PTFE sheathing (usually 0.030" thick) entirely shields the inner metal parts, making them immune to most harsh chemicals. These chemical-resistant heating elements work better in more corrosive settings than regular metal or quartz heaters, and they don't need gas purge systems.
Long Service Life and Quality Assurance: The low watt density design (around 10 W/in² or 1.5 W/cm²) keeps the device from overheating and makes it last longer. A normal one-year warranty (which can be extended) backs up the fact that many customers say they have had reliable service for 5 to 8 years or more in continuous acid bath operations.
greater Value: Same quality as high-end brands but at lower prices; same price level means longer-lasting and greater corrosion protection.
Energy Efficiency and Safety: This unit has great thermal conductivity and is non-stick, which means it uses up to 20% less energy than similar units. Grounded construction and protection against high temperatures make operations safer.
