Industrial Electric Heaters

industrial electric heaters

What Are Industrial Electric Heaters? An industrial electric heater converts electrical energy into heat energy. Industrial heaters come in many sizes, applications and heat transfer methods, but the process is basically the same. An electric circuit is created using a material with high levels of resistance.

That resistance creates thermal energy, which is passed on through a medium for your intended application. At Hi-Watt, we work with you to size your electric heater for your application. Use a state-of-the-art electric heating product to replace a gas-fired heater or to expand your industrial processing services.

Benefits of Industrial Heaters

Modern industrial heating requires an accurate heat profile and environmentally friendly operations. Use industrial electric heaters in place of gas-fired heaters to enjoy the following benefits.

  • Eco-Friendly Heating: Environmental concerns have many companies moving away from fossil fuel dependency. There are many eco-friendly electricity generation alternatives that are being explored, so transitioning your heat systems to electricity is a great way to stay ahead of the curve. A shift toward electricity-powered operations allows you to reduce your carbon footprint and promote a greener operation.
  • Heat Control A common misconception of electric heat is that it lacks heat control capabilities. Modern electric heaters compare very favorably with gas-fired alternatives in terms of heat control. Dial in your heater using a dynamic controller system from a leading manufacturer. At Hi-Watt, we offer the controllers you need to adjust the rise in temperature rate, overall heat level and other factors.
  • Energy-Efficient Operations Reduce the total cost of operations with an energy-efficient electric heater. Compared to older heating alternatives, a modern electric unit can heat your product with less energy use. This occurs through reduced waste and a range of acceptable voltage options.
    • Common Types of Industrial Style Heaters

      Commercial electric heaters come in many different types. These types vary based on the medium being heated, the level of heat required and the physical dimensions of the vessel. Compare the common types of heaters available at Hi-Watt to see how you may be able to update your facility:

      Strip heaters: Create convection or surface heat with a strip heater. This style of heating is common in vulcanizing, dehumidifying, air conditioning and food packaging.

      Band heaters: If you have a pipe or tube of liquid that needs to be heated, a band heater is an ideal option. Small and effective, this type of heater uses conduction to heat products for injection molding and extrusion.

      Immersion heaters: These heaters are secured to the side of a container or placed over its side to heat up a reservoir of liquid or gas. Immersion heaters use durable sheathing to protect against corrosion and other factors. Types of immersion heaters include immersion heaters for water, flanged immersion heaters, screw plug immersion heaters, over the side immersion heaters and more.

      Industrial infrared heaters : Use a radiant tube heater to heat, dry or cure a material in your facility. These heaters use infrared heat to cure paint, remove moisture or heat up plastic components.

      Cartridge heaters: Similar to immersion heaters, cartridge heaters use a durable sheathing to protect the heating element and promote consistent heating. They’re also known as insertion heaters or rod heaters.

      Air/duct heaters: Transfer heat through the air with a finned strip heater, heat gun or custom air heater. This is a common style of heater for use in forced air facility heating, but can also be used to transfer heat in a manufacturing process.

      Tubular heaters: This style of heaters come in a stunning range of styles and grades of materials. They’re designed for high temperature capabilities, custom heat transfer options and a variety of transfer media. Ask about our common styles or order a custom tubular heater for your facility.

      Heated hoses: Heat liquids as they pass through a hose with this style of heater. It’s commonly used in chemical transfer, packaging, tar dispensing and extrusion processes.

      Flexible heaters: Heat unusual shapes or vibrating components with a silicone flexible heater. Customize the shape of your flexible heating products to meet unusual processing demands.

      Cable heaters: Tight spaces require compact heating products. Cable heaters are commonly used in semiconductor manufacturing, food processing and plastic injection molding situations where space is at a premium.

      Circulation heaters: Heat fluids that flow past or circulate around the heater with a circulation heater. This style of heater can be used to heat your product directly or transfer heat through a liquid medium.

      How Do Industrial Heaters Work?

      These heaters require a fuel source to operate. In the past, the most common fuel sources were fossil fuel based. These include diesel, gasoline, kerosene and fuel oil. Some industrial style heaters moved to hot water and steam power, but this process can be highly inefficient.

      Today, industrial electric heaters offer an effective alternative. These heaters can be powered with single- or three-phase power, with either direct or alternating current. The voltage can also vary considerably to match your existing power and heat requirements. Advances in solar and wind power may make these renewable electricity options practical power sources for electric heaters in the future.

      Methods of Heat Transfer

      Industrial electric heaters operate based on heat transfer. This can occur in one of three ways: conductive, convective and radiant. Understanding the differences of these types can help you better choose the ideal heater for your process.

      Conductive: Heat transferred through conduction passes through solid materials. Particles in the solid material vibrate and pass the heat through the material and to other materials in contact with it.

      Convective: Convective heat transfer operates in a similar way, but by transferring heat through liquids and/or gases. Convection heaters include duct heaters, but also immersion and circulation heaters.

      Radiant: Industrial heaters can use electromagnetic waves to heat up an object. Just like direct sunlight, radiant heat heats objects thoroughly and can be combined with convection or conduction.

      Industrial Electric Heater Applications

      The diverse range of industrial heater designs and materials reflects the dynamic ways these components are used in commercial facilities around the world. From a food service small business to a multi-national metal heat treatment service provider, industrial electric heaters need to meet many unique demands. Here are some of the most common applications of industrial heaters:

      • Melting
      • Annealing
      • Drying
      • Curing

      Some applications require long periods of low temperature, while others require short bursts at incredibly high temperatures. The transfer medium, material and insulation material are all carefully matched to the industrial application for best performance.

      How To Choose the Best Industrial Electric Heater

      Start a conversation with our team at Hi-Watt about your electric heating needs. Discuss the medium you need to heat. Other factors include the length of time and temperature needed.

      Finally, you need to consider your surrounding facility. What electrical power is available for your new heater? Do you have enough space to install any type of electric heater, or do you need a compact heater?

      Answering these questions can help you narrow the list of available industrial electric heaters. Update your existing facility or plan a new process with the latest in heating technology.
