A heating coil is a device that is placed within a tank or container to heat a substance by using Joule heating to transform electrical energy into heat energy. Heat coils spread the heat over a broader area of the machinery, which lowers the stack temperature and enhances the effectiveness of coil heating. Just the interior surface of the coil receives direct radiation-based heat transfer. Compared to other heaters, they are intended to provide more efficiency. The demand for secure heating apparatus led to the development of these coils.
Powered by these factors, the market for heating coils is likely to experience higher than anticipated demand over the next several years. Business Research Insights predicts that this market’s valuation could touch USD 15.09 billion by 2028. It is also estimated that the market will register a CAGR of 2.9% between 2022 and 2028.
Business Research Insights™ Presents the Top 5 Band Heaters in the Heating Coil Industry
1. Ceramic Band Heaters
Energy conservation and operational efficiency can be met by ceramic-insulated band heaters. They can produce greater temperatures, which are necessary to manufacture the resins of today. Implementing a 1/4" electrical conduit can reduce electrical usage. A thick blanket made of ceramic fibres that reduces power consumption by 25–30%. The ceramic fibre insulation has a low thermal conductivity, so when the heater’s exterior surface temperature is around 400oF, the interior surface temperature is 1200oF.
The ceramic band heater is a flexible heater with special energy-saving attributes.
2. Duraband Heaters
The Duraband heater is a dependable mica-insulated band heater that can operate at higher temperatures (up to 900oF(482oC)) required to process resins at high temperature. It also provides the long-lasting, effective service required for the high productivity of injection machines, blow moulding machines and plastic extruders. The Duraband Heaters can also be configured in odd shapes, including rectangle, ring, hexagon, square and cone
The Duraband heater is more affordable, adaptable and widely utilized.
3. Maxiband Heaters
Maxibands heaters are designed to only heat, heat and cool or just cool. A 315-mm-diameter tubular heating element fits perfectly into the channels in the extruded aluminium track, which also serves as a great heat sink for quick transferring of heat and consistent temperature, which makes it a key heater in the market for heating coils.
Maxibrand heaters are robust, contamination-resistant, and have superior heat transfer.
4. Mi-Plus Band Heaters
Applications requiring high watt densities (W/in2) and/or high operating temperatures can benefit from the Mi-Plus band heater. Temperatures up to 1400oF(750oC) and watt densities up to 150W/in2 (23.25W/cm2) are both achievable with Mi Plus band heaters. The size of the heater and its working temperature will determine the suggested maximum watt density for a particular application.
Mi-Plus band heater is able to withstand higher watt densities and temperature.
5. Tubular Band Heaters
Under the worst circumstances, tubular band heaters can function, making them a robust band heater in the heating coil industry, particularly recommended for heating applications where plastic overflow or other pollutants frequently cause early heater burn-out on nozzle band on plastic injection moulding machines.
High-temperature resins and Teflon can be processed with great success using these machines.
Key Developments in the Heating Coil Industry
HC Coils
Privately held manufacturing firm HC Coils Ltd. specialises in the development and production of heat exchanger coils and coil-based products in the heating coil industry. These items are utilised in the UK, Europe, and other parts of the world for a variety of purposes.

Backer Hotwatt
Backer Hotwatt, founded in 1952 and a global leader in the market for heating coil and a pioneer in the production of resistance heating elements for more than 65 years, started out by producing just one item: the open coil heating element. Since then, the company has added heaters for the crankcase, air process, immersion, band, foil flexible glasrope, strip and finned strip, and tubular and finned tubular strip to their product line.
January 2023: Backer Hotwatt works directly with clients to design heaters specifically for their engines' needs, developing specialised solutions for hydrogen fuel cell engines that must run in demanding situations.
What Lies Ahead for the Heating Coil Industry?
Customized equipment is being developed by the manufacturing sector, which is expected to increase the market for heating coil and spur market expansion. Industry adoption of the product is anticipated to be encouraged by the availability of application- and order-specific items. Also, the market for the product is probably going to rise due to the desire for high-voltage electric heaters, particularly for passenger and commercial vehicles. As original equipment manufacturers look for growing revenues in developing nations, the need for high-voltage coils is projected to increase in those companies.
