Finned Heating Tubes

Equipped with expanded surface fins to maximize heat transfer. Ideal for: Forced air heating, drying ovens, and HVAC systems

  • Overview
Finned tubes feature metal fins (stainless steel or carbon steel) wound around the element surface to expand the heat dissipation area by 2–3 times. This significantly improves heat exchange efficiency and lowers the surface temperature of the element.
  • Customization Advantage
We can match the exact fin density and tube shape (W, U, or straight) of your existing oven or dryer, even for a single replacement unit.
Technical Specifications Range / Typical Values
Voltage Range 12V / 110V / 220V / 380V / 480V
Power Range 500W – 10kW (Custom lengths available)
Resistance Range 5Ω – 500Ω
Current Range 2A – 30A
Common Diameters Φ8mm, Φ10mm, Φ12mm, Φ16mm

Heating Tubes

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?
