 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 common 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. The electric heating system distributes 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 use this type of electric heating system. As well, the heaters also see use in many essential processes like power generation and refining of gas and oil. Another common name for electric process heaters is immersion heaters.    

Manufacturing Details

An immersion/electric heater has a metallic base, which they weld 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 coats 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 shock resistant for safety, they still require careful handling of 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 it adjusts the temperature of the heater and manages 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 at the exterior wall of the tank or the mechanism’s housing 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 exposure out into the open. This is much safer and the trend is emerging rapidly.

Besides liquid content, gases are also receive treatment from electric heating systems. This is why these are widely used in most industrial manufacturing processes. For more details, contact us today.
