W-Shape Finned Tubular Heater: High-Efficiency Air Heating Solution

Product Overview

Our W-Shape Finned Tubular Heaters are specifically engineered for forced convection air heating applications. By wrapping continuous spiral fins around a high-quality tubular element, we significantly increase the surface area—up to 3 times compared to standard tubular heaters. This design allows for faster heat dissipation, lower surface temperatures, and a much longer service life for the heating element.

The unique W-bend configuration provides a compact footprint while maximizing the heating path, making it the ideal choice for industrial ovens, ducts, and load banks.

Technical Features

• Superior Heat Dissipation: The helical-wound fins create a large surface-to-mass ratio, ensuring rapid heat transfer to the moving air stream and preventing overheating of the element.

• W-Shape Compact Design: Precisely formed to provide high power density in restricted spaces, ensuring uniform air warming across the entire cross-section of your equipment.

• Rugged Construction: Built with premium stainless steel or Incoloy sheaths and fins (SS304/SS321/SS310S) to withstand high-velocity airflow and corrosive environments.

• Safe Terminal Termination: Equipped with heavy-duty mounting studs and high-temperature ceramic insulators to ensure stable electrical connections and prevent short circuits.

• Customizable Watt Density: Optimized for specific airflow velocities to ensure maximum efficiency without compromising the heater's structural integrity.

Specifications & Options

• Fin Material: Stainless Steel (Standard) or Copper (for specialized applications).

• Tube Diameter: Available in 8mm, 10mm, 12mm, 16mm (Customizable).

• Bending Patterns: W-shape, U-shape, or M-shape to fit your specific housing.

• Mounting Options: Available with or without mounting brackets/flanges for easy installation.

• Voltages & Wattages: Fully customizable to meet global electrical standards.
