An electric process heaters is a specialized device designed to heat various substances in industrial applications using electrical energy. An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor and works on the principle of Joule heating, an electric current passing through a resistor will convert that electrical energy into heat energy.
Electric process heaters use electricity to increase the temperature of liquids and gases within process systems. Depending on the application, electric process heaters may be used for both direct and indirect heating, which makes them a particularly versatile heating option.
Types of Industrial Electric Process Heaters
Immersion Heaters
Immersion heaters are submersible in the substance they are heating, making them ideal for liquids like water, oil, or chemicals. They are versatile and efficient, directly transferring heat to the liquid.
Circulation Heaters
Circulation heaters feature a heating element immersed in a vessel, promoting fluid circulation through the heater. This design ensures uniform heating.
Band Heaters
Band heaters are cylindrical devices wrapped around a pipe or vessel, providing direct heating to its surface. They are commonly used for applications requiring a consistent and efficient heat transfer.
Flanged Heaters
Flanged heaters are attached to a tank or vessel using a flange, allowing for easy installation and removal. They are suitable for heating gases and liquids in industrial processes.
Process Air Heaters
These heaters are specifically designed for heating air in industrial processes. They find applications in drying, curing, or any process requiring heated air.
Electric Process Heater Considerations
When selecting the best electric process heater for your application, it is important to consider the needs and limitations of your equipment.
- Fluid flow rate: Consider the volume or the flow rate of fluid to be heated to determine the heater’s required capacity.
- Process temperature: The greater the temperature increase, the greater the power output required.
- Thermal properties: The fluid’s thermal and physical properties help to determine the appropriate watt density.
- Footprint: Space and other physical limitations must be considered when determining the heater’s size and placement.
