How to select a Heater for the Industry?

There are a variety of applications for industrial heaters. It is used in different processes where the temperature of an object or process needs to be increased. Process heating is a significant part of the manufacturing industry. Even the oil and gas, food processing, and chemical refining industries use heaters in their manufacturing processes. The plants use it for generating steam, heating heavy liquids like crude oil or its derivatives, melting or joining metal and alloys, and different other purposes. It is used in making products like asphalt or concrete.

To put it in simple language, industrial heaters convert the energy from fuel or other sources into thermal energy in a process stream, system, or closed environment. Many types of heaters and heating applications are used across industries in India, but what exactly will be suitable for your project depends on various factors. Selecting the appropriate heating element will save money and time and increase efficiency.

Few points you need to consider before you seek to find the ideal heating solution for your project:

What type of heat source will you be utilizing for the heater?

To generate thermal energy, industrial heaters require a source. The source can be various. For instance, electricity, wood, solar hot water, liquid fuels, and gaseous fuels. The commonly used sources are bio-mass, geothermal and solar sources that offer heat to provide support to different industrial processes serving air-heating and water heating usage.

What can be the ideal temperature for the heating element?

Perhaps, the most significant criterion while selecting an industrial heater is the maximum operating temperature. This temperature is rated on the heater. The operating temperature varies depending on the application.

The temperature depends on certain factors. These include the shape of the heater, the types of material the heater is made of, and the material that needs to be heated. Metallic heaters made of tungsten or ML can reach a very high temperature between 800°C and 1000°C. Usual industrial heaters can reach a temperature of up to 650°C.

Most of industrial heating needs is met with temperature below 750*F. On the other hand, some industries like restaurant, cooking and agriculture requires a much lower temperature.

Remember that the operating temperature will be suitable depending on the material that is to be heated.

What should be the heating capacity of the heater?

Usually mentioned in kilowatts, heating capacity is the thermal energy the heater can deliver in a certain period. It depends on various factors like the mass of the fluid, temperature change, the specific heat capacity of the machine, and the time taken to attain the temperature.

What kind of control do you expect?

Most of the heater manufacturers in Mumbai provide a customized solution. So, it depends on the requirement of your project and how much control you will need. You can discuss this with the service provider and work on the best solution.

What are the different types of industrial heaters?

There are four primary industrial heaters. These include screw plug, over the side, flanged, circulation and traditional heaters.

What is the period for which your heating element will be active?

Heaters can be used for different purposes- to soften a part, curing and temper, transform material from solid to liquid, and embed or install another part. So, it depends on the usage of the model that will be fit for you.
