Electric Heaters and Their Use in Industrial Processes

There exists a wide range of industrial heaters that are used in a number of different processes; out of these, the electric heater is yet important another type. These are commonly used in pulp and paper mills where constant voltage fluctuation results in deterioration of the final product. Electric immersion heater ensures that the calendar roll comes out just the right way in this particular industry.

In case of improper heat supply, a few chemicals also form up lumps, which cause issues in the productivity. Electric heating system is installed to distribute the heat evenly to every corner of the content container.

A Brief Overview of Industrial Electric Process Heaters

A device or heater that utilizes electricity to heat up chemicals, gases or any other liquid within a tank is known as an electric process heater. Mostly, thick chemicals like fuel, oil, ammonia, petrochemical fluids, nitrogen and even water are treated with this type of electric heating system. Aside from this, the heaters are also used in many different essential processes like power generation and refining of gas and oil. Electric process heaters are also known as immersion heaters in a simplified term.



Manufacturing Details

An immersion/electric heater has a metallic made base, which is welded very carefully on to the device itself. Most common design and outlook for this type of heater is flat or long having a tubular shape. Variation in shape and size is also due to the difference in company manufacturing. Nickel Chromium wire of superior quality is used as a coating, which is applied at each heating rod. Magnesium Oxide, which is an electric insulator, is also applied to the gadget for faster heat transfer and as a rust and corrosion preventer.

Although, the heater itself, along with each part, is made to be shock resistant for safety, but still one must be very careful while handling the contraption. Be sure to take all the precautions prior to working on the device. A controller box is either built-in or adjustable, and is used to adjust the temperature of the heater and manage the entire heat transfer process.

Technical Specifications

For technical details regarding industrial electric heaters, kindly read the information given below.

Voltage – 24Vdc to 3x690Vac

Immersion Length – As per requirement

Temperature Control – Fixed or adjustable

Heating Material – Brass or stainless steel

Control Box – Electrified silumin or copper, coated steel

Remember that the above given technological details may vary depending on the heater type, its applications as well as if it is manufactured by any other company.


Heating Process: How It Is Done

Electric immersion heaters are mounted over and adjusted to a tank having chemicals, oil or even water. You can monitor and control the entire heat transfer process either by making adjustments to the control box located at the exterior wall of the tank or the mechanism is housed in a separate room known as a “closed system”.

This particular room has all the switches, panels and visual monitoring tools with which you can operate the heater without it being exposed out into the open. This is considered much safer and the trend is emerging rapidly.

Besides liquid content, gases are also treated with electric heating systems, which is why these are widely used in most industrial manufacturing processes.
