What Is a Flanged Immersion Heater?

If you are looking for a reliable source of heat, then flanged immersion heaters might be right for you. While there are plenty of immersion heaters for water, flanged immersion heaters feature several hairpin elements, bugle tubular elements, and an ANSI-rated flange that provides direct heat application to a liquid medium, heating it up. If you find yourself in a situation where you need to warm up liquid, then there is a chance that this could be the best industrial electric heater for you. Learn more about how this heater works below, and remember to reach out to a professional with any questions you might have.

How Do Immersion Heaters Work?

If you are looking for immersion heaters for water, it is important to learn more about how this works. An immersion heater works by directly heating the water surrounding it. There is a heating element immersed in the water. Then, a strong electric current is passed through it. This causes heat to come in contact with the water, warming it up. This is very different from a gas water heater, which uses a burner underneath a container that heats the water. An immersion heater commonly comes with an isolating switch that is connected to the electrical supply. This creates the energy that is required to heat the water itself. There are some situations where an immersion heater can help someone save time and money on their heating expenses.

Benefits of Flanged Heaters

There are several critical benefits of flanged immersion heaters you will enjoy. These include:
  • They are among the most widely used heating options on the market today.
  • They are significantly easier to stall, helping people save time and money on their heating installation processes.
  • They’re designed to be used specifically with pressurized vessels, making them far more manageable.
  • They can be used to heat a wide variety of grades of oil, making them more versatile than some of the other choices.
These are just a few of the many benefits of flanged heaters. If you want to get the most out of your heaters, you need to work with a professional who can place you in the best position possible to succeed.

Common Applications of Flanged Heaters

There are several common ways these industrial electric heaters can be used. For example, they are commonly used to heat water, preventing it from freezing during the winter months. They can also be used for viscosity maintenance, making sure materials are still able to move easily. They can even be used to maintain control of hazardous chemicals that require a specific temperature range to keep them safe and usable. There are even situations where heaters can be used to take care of oil, which is used throughout numerous industries. Because there are so many applications of flanged heaters, they are among the most commonly used heaters today.

How To Choose an Immersion Heater

If you are looking for immersion heaters for water or oil, there are several factors you should consider when trying to locate the right heater. For example, you need to pick the right sheet for the fluid you are heating. You also need to select the right power density, which is usually quantified in watts per square inch. Finally, you also need to select a heater with a wattage that is high enough to heat your fluid to the appropriate temperature. Because there are so many factors to consider, it is helpful to work with a professional who can help you evaluate industrial electric heaters. If you want to find the right heater, then rely on the team from Hi-Watt, Inc. to help you. It would be our pleasure to help you find the right heater.

Watlow Immersion Heaters

Watlow flanged immersion heaters are made with WATROD or FIREBAR tubular elements brazed or welded to a flange. Stock flange heaters are equipped with a general purpose terminal enclosure. These heaters, with FIREBAR elements, also answer the need for liquid immersion applications requiring high kilowatts in small tanks. The FIREBAR element’s unique flat surface geometry packs more power in a smaller bundle, with lower watt density, making it especially well-suited for petroleum-based liquid heating applications. In addition to flanged immersion heaters, Hi-Watt Inc. carries a wide variety of other types of immersion heaters including over the side immersion heaters, and screw plug immersion heaters.
