Figure 1: Custom Bending Capabilities for Sauna Furnaces.
We support complex 3D bending for compact sauna furnace designs. Standard minimum bending radii depend on the sheath diameter. (e.g., U-Shape, Multi-loop, Spiral).
SECTION 2: Industrial Applications
Our heating elements are the core component for:
-
Residential Sauna Furnaces: Compact, high-watt density elements for sauna home units.
-
Commercial Electric Sauna Stoves: High-durability elements for gyms and hotels.
-
High-Temperature Process Air: Air heaters requiring max sheath temps of 800°C.
SECTION 3:Material Science: Why We Use Compacted MgO
To ensure the safety of your sauna furnace, we use high-purity magnesium oxide (MgO) powder. This powder is vibrated and compacted to rock-hard density. This process provides:
-
Maximum Heat Conductivity: Efficiently transfers heat from the Ni-Cr wire to the sheath.
-
Optimum Dielectric Strength: Insulates the current from the outer sheath, preventing short circuits even in humid sauna conditions.
SECTION 4:Quality Assurance & Terminal Construction
For OEM clients, connection reliability is paramount. We use a threaded screw terminal with ceramic or mica insulators to provide a positive, vibration-resistant connection from the lead wire to the terminal. The integral cold pin is fusion welded to the resistance wire to ensure the electrical connection point remains within safe operating temperatures.
SECTION 5: FAQ (Manufacturing Focus)
Q: What is the MOQ for custom sauna furnace tube heater manufacturing?
A: For custom designs requiring new bending molds, our typical MOQ is 50-100 pieces. However, for standard straight lengths or common diameters (8mm/10mm), we can support smaller trial batches for prototyping.
Q: Can you laser etch our brand logo on the sauna tube sheath?
A: Yes, we offer OEM branding services. We can laser etch your company name, voltage, and wattage ratings directly onto the sheath material (e.g., Incoloy 800) for brand identification.
Q: Do you offer design assistance for new sauna furnace models?
A: Yes. Hongtai engineering is available to assist with the design and development of special heaters for particular requirements37. We can help calculate surface load (Watt Density) to ensure the element does not overheat in your specific furnace airflow design.
