Our vertical PTFE immersion heater is specially designed for heating corrosive liquids in electroplating tanks, acid pickling baths, chemical plating solutions, and laboratory environments. The outer tube is made from high-quality imported PTFE material, with an inner core of premium stainless steel or nickel-chrome heating elements. It offers exceptional resistance to strong acids and alkalis, compatible with nearly all chemicals (except molten alkali metals). The vertical design allows easy immersion installation, providing uniform and efficient heating. This makes it an ideal choice for demanding applications in electroplating, chemical processing, electronics, and laboratory settings.

We are a professional manufacturer specializing in PTFE immersion heaters, with our own modern factory spanning over 8,000 squre meters. With more than 10 years of experience in electric heating elements, we handle the entire production process in-house - from raw material processing to finished assembly. Equipped with fully automated production lines, imported PTFE extrusion equipment, and advanced testing instruments, our monthly capacity exceeds 150,000 units. As a true source factory, we eliminate middlemen, offering you competitive factory-direct pricing and guaranteed quality.
Production Capacity & Lead Time: Standard products in stock for quick shipment (7-15 days); Custom orders: 15-30 days. Our robust capacity ensures on-time delivery even during peak seasons!
Outstanding Corrosion Resistance: Made with DuPont-grade PTFE tubing, uniform thickness with no pinholes - withstands long-term immersion in aqua regia, concentrated sulfuric acid, and other harsh chemicals without damage.
· Premium Materials: Imported alloy heating wires and thick-walled PTFE sheath for quality far superior to standard market options.
· Safe & Reliable: Low surface load design + built-in over-temperature protection to prevent dry-burning risks.
· High Efficiency: Uniform heating with over 95% thermal efficiency - energy-saving and environmentally friendly.
· Long Service Life: Rigorous craftsmanship ensures 5-10 years of reliable performance under normal use.
Every heater undergoes strict testing before leaving the factory to guarantee zero defects:
High-Voltage Test: Using hi-pot testers, withstands over 3000V without breakdown.
Insulation Resistance Test: Megger shows >500MΩ.
Corrosion Immersion Test: Soaked in strong acid/alkali solutions for over 72 hours - no leakage or deformation.
Power Accuracy Test: Precision power meter ensures deviation <±5%.
Pinhole Detection: Specialized equipment scans PTFE coating for any micro-defects.
Aging Test: Simulated continuous operation for 1000+ hours.
Q: Do you accept customization?
A: Yes! As a direct manufacturer, we offer full customization including power, voltage, dimensions, and shapes (vertical, L-type, spiral) tailored to your tank requirements.
Q: What is the minimum order quantity (MOQ)?
A: Standard products: 1 unit (perfect for samples/testing); Custom products: Recommended 10 units for optimal production and cost efficiency.
Q: What about after-sales service?
A: We provide a 12-month warranty - free replacement for non-human damage. Lifetime technical support with responses within 24 hours.
Q: How is the product packaged?
A: Individual units are packed with anti-shock foam + sturdy carton; Bulk orders use reinforced wooden crates or frames to prevent damage during transit.
Q: How do you ship?
A: We support multiple options including SF Express/Debon for domestic, logistics lines, and freight. Small orders ship via express (free shipping to most areas); Larger orders via cost-effective logistics. International: Sea/air freight or express available.
