The Aluminum Extruded Heater Profile is an integrated heating solution consisting of an aluminum alloy extruded housing with a precision-embedded stainless steel heating tube. Unlike PTC or fin-type heaters, this design offers higher power density, uniform surface temperature, and greater durability under continuous industrial operation.

The extruded aluminum profile serves both as the heat sink and the structural housing, eliminating the need for separate mounting of heating elements. This results in faster heat transfer to passing air and a more compact overall heater assembly.

Technical Specifications

【Key Features】

1. Integrated One-Piece Construction
The heating tube is cast or press-fitted into the aluminum extrusion during manufacturing. No separate assembly required – reduces installation time and eliminates loose connections.

2. Uniform Heat Distribution
Aluminum's high thermal conductivity (200-220 W/m·K) ensures even heat spread across the entire profile surface. Temperature variation ≤8% across the length.

3. High Power Density
Achieves 5-15 W/cm² compared to 1-3 W/cm² for PTC fin heaters. More heat in less space – ideal for compact industrial air heaters.

4. Multiple Mounting Options

• Flange mounting for duct integration

• Through-bolts for fan housing attachment

FAQ

Q: Can this be used in a ducted air heating system with high static pressure?
A: Yes. The smooth or low-profile extruded shape minimizes pressure drop. Flange mounting is recommended for duct integration.

Q: What is the maximum continuous operating temperature?
A: The aluminum housing surface should not exceed 550°C. For applications requiring higher air outlet temps, we recommend Incoloy-sheathed tubes or switching to open coil design.
