When it comes to controlling the environment of your application, heat and temperature are crucial aspects to consider. Selecting the right heating element allows you to ensure the level of safety, allows you to attain optimal performance, and improves the overall efficiency of the heater's end use.
When the right heater is selected, you also save money on operational costs by buying the right product up front, thus reducing the time in the development cycle and improving your time to market. Heater requirements vary significantly depending on the market and application. Industries for medical devices, packaging equipment, laboratory and analytical equipment, semiconductor testing, food service, fuel cells, and opto-electronics all use heating elements as a core technology in many of their products.
The types of heaters used in these products are equally diverse. Tubular, cartridge, strip, band, foil, rope, ceramic, and silicone are all heating element technologies that can be used to heat air, gases, liquids, and solids. So, how do you pick the right heater? Even if you think you know what you want or need, there are several questions to consider. Answering them will ensure you choose the right heater and that it is applied correctly in the application.

Backer Hotwatt Heater Examples
Our team encounters situations almost daily where the answer to the above questions have played a factor in the final heating equipment decision.
We had a customer call requesting a standard cartridge construction heating element with a high wattage, but through our conversations with them and discovering the size envelope and wattage required, we determined that it’s best to construct the specific heater, in this case as one of our Superwatt® units, that have higher allowable watt densities in the same envelope.
In a similar scenario, a customer wanted to heat air with one of our standard air process heaters. Through our discussions, we discovered the amount of airflow they’re looking to heat was a high amount of about 100 CFM. Due to this requirement, we were able to suggest and design a Maxi-Flow element, which is capable of heating in-line air up to 200 CFM.
One final example includes a customer looking to heat a giant platen or punching sheet. They were originally looking at our foil heaters, which cover large surfaces. However, they wanted to heat the platen up to 350 degrees Fahrenheit, which informed us that it would be best to redesign a system to bore holes inside the platen in order to fit some cartridge heaters, which have a higher temperature output and would, therefore, provide a more consistent heat.
