Aluminum Finned Heating Tubes

Aluminum Finned Heating Tubes: High-Efficiency Air Thermal Transfer

Aluminum Finned Heating Tubes are engineered to solve the core challenge of air heating: air’s natural resistance to absorbing heat. By permanently bonding or tension-winding high-grade aluminum fins onto a stainless steel or Incoloy® tubular element, the surface area is increased by up to 10 to 20 times. This allows for significantly higher wattage in a compact space while keeping the sheath temperature lower, ensuring safety and a longer heater lifespan.
We offer non-standard fin spacing and thickness to match your specific airflow and pressure drop requirements in dehumidifiers or HVAC units.
Technical Specifications Range / Typical Values
Voltage Range 100V – 240V
Thermal Efficiency >30% higher than steel-finned tubes
Resistance Range 30Ω – 400Ω
Current Range 1A – 15A
Fin Diameters 25mm, 35mm, 50mm options

Maximum Heat Dissipation: The aluminum fins act as a high-conductivity radiator, rapidly stripping heat away from the internal element and transferring it into the moving air stream.

 

Lower Sheath Temperatures: Because the fins dissipate heat so effectively, the internal heating element runs cooler than a standard “bare” tube at the same wattage, preventing element burnout and “red-heat” hazards.

 

Enhanced Energy Efficiency: Achieving the desired air temperature requires less time and energy due to the optimized thermal contact between the fins and the passing air.

 

Corrosion & Lightweight Design: Aluminum fins provide excellent resistance to atmospheric corrosion and add minimal weight to the system, making them ideal for HVAC and portable equipment.

Precision Industrial Heating Elements: Engineered for Your Exact Needs

At Runkel, we don’t just manufacture heating tubes; we provide thermal solutions. Our core strength lies in our unmatched customization capabilities.

Whether you are a researcher needing 1–2 prototype samples for a new project, or a maintenance manager looking to replace a discontinued or aging heating element in your existing machinery, we deliver perfect-fit solutions with no minimum order hurdles.

Why Choose Us? — The Customization Specialist

“From 1 unit to 1,000—we treat every prototype with production-grade precision.”

  1. Zero Minimum Order Quantity (No MOQ)——Most factories turn away small orders. We embrace them. If you need a single tube for a performance test or a rare replacement, we are your dedicated partner.
  2. Perfect Replacement & Retrofitting——Is your old equipment failing because the original parts are no longer available? Send us your drawings, photos, or the physical old part. We will reverse-engineer a 1:1 precision replacement that fits your existing mounting holes and electrical specs perfectly.
  3. Bespoke Engineering Specs——Materials: SUS304, 316L, 310S (High Temp), Incoloy, Titanium, and more.——Dimensions: Diameters from 3mm to 25mm+, custom lengths, and complex bending.Electrical: Optimized for your specific voltage (12V to 480V) and wattage requirements.

How We Work

  1. Engineering Review: Our team verifies the power density and material compatibility for your application.

  2. Agile Production: Your custom order enters our flexible production line immediately.

  3. Quality Assurance: Every unit undergoes rigorous insulation and leakage current testing before shipping.

Do you have a broken heating element that needs replacing, or a new project that requires a custom fit?
