Tubular elements can be used in a range of applications from air, water, oil, chemical solutions and defrost. They are a versatile means of heating an application and can be straight or formed to a required shape and can reach temperatures of 800°C. A tubular element consists of nickel chrome resistant wire which is spot welded to a terminal pin, the nickel chrome wire is insulated by MGO powder which is then housed in an outer sheath.
When choosing a tubular element for a certain application there are set parameters that need to be considered. Whilst standard requirements are wattage and voltage, other parameters are sometimes not so obvious. Sheath wattage must also be considered which determines the working surface temperature of the element – this can be critical to the application as many of the media in which our elements are applied will have maximum contact temperatures. Aspects such as electrical and mechanical connections must also be considered at the design stage.
