When is it necessary to use a customized shape in a finned heater?
Use a custom shape when a standard straight or U-shaped heater doesn't fit or doesn't heat evenly.
Common Reasons to Customize the Shape:
- Limited or Odd-Shaped Space
The duct or equipment has bends or tight spaces.
- More Even Air Heating
Custom shapes like S or W help spread heat better.
- Need More Heating Area
Coiling or bending the heater adds more surface area.
- Avoid Other Parts
You need to route the heater around sensors, wires, or flammable parts.
- Easier Installation
Shaped to fit mounting holes or brackets in your system.
Common Custom Shapes:
- Serpentine (zigzag) – for maximizing surface area across airflow.
- Circular or spiral – for heating in round ducts or cylindrical housings.
- L- or U-shaped – for specific directional flow or mechanical fit.
- M- or W-shaped – for compact, high-surface-area layouts.
