A Buyer’s Guide to Tubular Heaters

Tubular Heaters

In the world of industrial heating solutions, tubular heaters stand as a reliable and versatile option. Tubular heaters are electric heating elements designed with a tube-like structure, commonly made of stainless steel or other materials that offer excellent heat transfer properties. These heaters can be found in various industries, from manufacturing and processing to commercial and residential applications.


Understanding Tubular Heaters


What are Tubular Heaters?

Tubular heaters are versatile electrical heating elements designed to generate and distribute heat uniformly in various industrial and commercial applications. They consist of a metallic tube typically made of stainless steel or other alloys with electric resistance wire or a heating coil running through its core. When an electric current is passed across the heating element, it converts electrical energy into heat, warming the surrounding environment.

Components and Construction

Tubular heaters are constructed using high-quality materials to ensure durability and efficient heat transfer. The main components include:

  1. Tube Sheath. The outer layer of the heater, usually made of stainless steel, Incoloy, or copper-nickel alloy, protects against external factors and corrosion resistance.
  2. Heating Element. The heart of the tubular heater, either a resistance wire or a coil, is liable for converting electrical energy into heat.
  3. Magnesium Oxide (MgO) Insulation. A mineral-based insulation material fills the space between the tube sheath and the heating element, improving heat distribution and electrical insulation.
  4. Terminal Pins. Metal connectors at each heater end enable electrical connection to a power source.


Types of Tubular Heaters

Tubular heaters come in various configurations, each designed for specific applications and installation requirements.

  1. I finned Tubular Heaters. These heaters have fins attached to the tube sheath, increasing the surface area for better heat dissipation and higher efficiency. They are commonly used in air heating applications and for space heating in industrial settings.
  2. Straight Tubular Heaters. The most basic and straightforward design, ideal for immersion heating applications, liquid heating, and air heating where space is limited.
  3. U-Shaped Tubular Heaters. As the name suggests, these heaters have a U-shape, making them suitable for applications requiring a bent or formed heating element, such as in molds or specific industrial processes.
  4. Tubular Heater Bands. These are cylindrical heaters typically used for heating pipes, cylinders, or other cylindrical objects to maintain a specific temperature or prevent freezing in cold environments.

Each type of tubular heater offers distinct advantages, and selecting the correct configuration depends on the specific heating requirements and the intended application. Understanding the different types empowers businesses to make well-informed decisions when choosing the most appropriate tubular heater for their needs.
