In the manufacturing industry, many types of heating are done, but process heating makes a necessary part of it. Even if it is for producing steam or liquefying and connecting metals to create alloys, plants utilize industrial heaters in some or other forms. These heaters change fuel energy or different sources into heat. This thermal energy then goes to the system by the heat transfer procedure. So, here, we have discussed a few things that you should remember while buying an industrial heater for your plant:  

1. Features  

Now that you know the heat transfer method of industrial heaters let’s find out their distinctive features.  

  • Heating Ability: Generally indicated in kilowatts, heating ability illustrates how much thermal power the heater can provide in a period. It relies on the fluid mass, its particular heat ability, modification in temperature, and time used to reach the temperature.  
  • Highest Operating Temperature: Perhaps the most important specification while selecting an industrial heater, the maximum operating temperature, is the rated temperature of the heating element. 
  • Pressure Valuation: Maximum running pressure at which the oil, water, or fluid heaters can be run.  
  • Highest Air Flow: Highest airflow is essential for all air heaters and outlines the overall capacity that it can heat. Airflow reads out the maximum temperature a heater can reach and how long it can hold a particular temperature.  
  • Watt Frequency: Many electrical heaters use an AC source in a single or three-phase working. In electrical heaters, watt density is the key feature that determines how fast heat can pass through the process and should be chosen correctly.  
  • Sheath or Sleeve Material: Most heaters utilize sleeves that safeguard and cover the heating attributes. From rubbers to polymers, metals to alloys, there are many choices for sheath material depending on the use.  
  • RoHS Conformity: RoHS is an EU mandate that directs all electronics and electrical tools to include minimum levels of dangerous materials such as mercury, lead, cadmium, etc.  
  • WEEE Consent: WEEE or Waste Electrical and Electronics Equipment is an additional EU directive that supports reuse, recycling, and recovery to reduce the environmental effect.  

2. Types  

Industrial heaters, such as thermal oil heaters, are present in different shapes, sizes, form-components, configurations, ratings, etc. Types of these heaters can be classified on the basis of their usage, fuel sources, mediums, and more:  

   A. Usage:  

  • Duct Heaters: Set in the moving surge of gas or air. The gas or air gets heated because it flows via the heater.  
  • Circulation Heaters: Employed to heat circulating or flowing fluid currents because they spread via them.  
  • Ring Heaters: Uniquely created strip heaters in a round shape that is employed to heat round shapes such as tanks, molds, flasks, etc.  
  • Strip Heaters: A plane heating device firmly fixed on the surface to heat either the surface itself or the enclosing air.  
  • Rope or Band Heaters: Adjustable heaters that can encase all over tubes, pipes, and different surfaces.  
  • Immersion Heaters: Heat the element by putting the heater rod inside it.  
  • Space Heaters: Compact heaters are made to heat sealed areas by emission.  
  • Screw-plug Heaters: Immersion heaters for small-scale usage that are functional and easy to set up.  
  • Over-the-side Heaters: Economic, responsive heaters with a waterproof body are mainly employed for heating liquids by inserting them via the top of containers or tanks.  
  • Explosion Proof Heaters: Include housing for the material being heated to hold off flames, eruptions, or sparks.  
  • Flexible Heaters: Can be formed to take the type of material getting heated.  

   B. Fuel Sources:  

  • Oil Heaters: Have metal lines that take in a cavity and heating part and set on fire liquid petroleum goods.  
  • Electric Heaters: Electric current goes through a high-resistance material and produces heat.  
  • Gas Heaters: Use gases, for example, liquefied natural gas, propane, etc., to produce heat.  
  • Solid Heaters: Use regular fuels, such as wood, coal, etc., to generate heat.  

  C. Medium:  

  • Water heaters  
  • Air heaters  

3. Different Applications  

Application areas of industrial heaters are never-ending. Here are a few key application industries that use them in some or other form:  

  • Petroleum Industry  
  • Water Treatment Plant  
  • Chemical Factories  
  • Nuclear Power Plants  
  • Oil & Gas Industry  
  • HVAC Systems  
  • Plasma Heating Systems  
  • Food and Beverage Companies  
  • Industrial Ovens  
  • Textile Plants  
  • Road Making Industries  
  • Steam Production  
  • Asphalt Manufacturing Companies  
  • Biomass Dryers
