A Flanged Immersion Heater is a heating element inserted into a liquid, typically a fluid used in industrial processes, to heat the liquid. The heater is generally made of metal and has flanges, or projecting flat surfaces, that allow it to be securely fastened to the tank or other container in which it is placed.

The heating element is typically powered by electricity and can be controlled using a thermostat or other temperature-control device. The electric Over-The-Side Immersion Tank Heaters are constructed of multiple hairpin bent tubular heating elements brazed or welded into a terminal housing.

What are the Applications for Flanged Immersion Heaters?

Flanged immersion heaters are used in a wide range of industrial settings, including factories, power plants, refineries, chemical plants, and other industrial facilities. They can be used for heating a variety of liquids, such as water, oil, chemicals, and other process fluids, in tanks, vessels, or other containers.

They are also used in many different types of equipment, such as boilers, heat exchangers, storage tanks, and process vessels.In addition to being used in industrial settings, flanged immersion heaters can also be found in commercial and institutional settings. For example, they may heat water in large commercial buildings or heat pools or hot tubs.

They can also be used in agriculture to heat water for animal care or heat liquids used in agriculture processes.Overall, Flanged immersion heaters are suitable for indoor and outdoor applications and can be designed to operate in a wide range of temperatures and pressures. It can be found in a wide range of applications where there is a need to heat liquids in a controlled and efficient manner.

How to Select a Flagged Immersion Heater?

Selecting the right flanged immersion heater for a specific application requires considering several factors, including:

  • Voltage and Wattage: The voltage and wattage of the heater must match the electrical power supply available at the installation site.
  • Heating requirements: The watt density (watts per square inch) must be appropriate for the liquid to be heated and for the desired temperature rise.
  • Flange size and material: The flange size and material must match the tank or container to which the heater will be attached.
  • Temperature control: A thermostat or other temperature control device must be selected that is compatible with the heater and the heating application.
  • Hazardous location: If the heater will be used in a hazardous location, it must be certified for use in such environments.
  • Compatibility: Make sure the heater is compatible with the liquid that will be heated, and that it can withstand the temperature, pressure, and chemical properties of the liquid.
  • Size: The size of the heater must match the size of the tank or container in which it will be used.
  • Safety features: Look for heaters with safety features like over-temperature protection, ground fault protection, and explosion-proof enclosures.
  • Brand reputation: Consider the brand reputation of the manufacturer, as well as the warranty period of the product.

It is also recommended to consult with a professional or an expert to ensure the best heater selection that fits your specific application and requirements.
