What is a strip heater?

Strip heaters are a very popular type of heating element. Typically, they consist of a resistance wire, a protective sheath (made from aluminium, steel or iron) and hardware to bolt them onto a surface.

Some models – usually those intended for radiant air heating – also come fitted with a series of fins. These maximise the heater’s surface area and allow heat to be transferred much more efficiently.
How do they work?
They may sound technical, but strip heaters work in a very simple and logical way. Essentially, an electrical current is passed through the resistance wire. As this wire is spaced evenly across the length and breadth of the element, it heats up its entire surface area. This heat can then be transferred via convection – either into the surrounding air or the object to which it is attached.
What can a strip heater be used for?
Strip heaters are most commonly found indoors, where they are used for numerous clamp-on and convection heating applications, such as:

– surface heating in platens dies, moulds, tanks and piping
– process heating in ovens and drying cabinets
– dropping resistors for line applications in railroads and load banks
– defrosting equipment in hoppers, conveyors, ducts and car heating systems

Thanks to a resistance wire that runs throughout their entire length, they offer uniform heat distribution – across the full surface area of the heater – and reach temperatures as high as 500°C. If you’re looking for a way to transfer heat, quickly and effectively, a strip heater could be the answer.
Which is the right strip heater for my needs?
Various lengths and watt densities are available – and the right one for you will depend on the operating temperature that you require. Generally speaking, a low watt density is recommended for higher temperatures and viscous materials (with a low thermal conductivity). High watt densities are better suited to lower temperatures and thinner materials (with a high thermal conductivity).

However, this is only a ‘rule of thumb’ and it can vary.
