Looking for a cost-effective way to heat a surface? Or perhaps the surrounding environment? Our UCI strip heaters could be the solution. Available at a competitive price, they’re a versatile and economical way to transfer heat via convection and a worthwhile investment for many applications.
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. If you’re unsure on the best strip heaters for your application, the best option is to get in touch with our experts – here at Under Control. We have unrivalled knowledge in this area and can advise on the ideal specification for your needs.
