Different Types of Tubular Heaters and Their Applications

Tubular heaters are widely used in various industrial applications for heating solids, liquids, gases. These heaters consist of a metal sheath containing a heating element and are available in various types, each with its unique features and applications. In this article, we'll discuss the various types of tubular heaters and their applications.

Finned tubular heaters are designed for heating air and gases. They have fins attached to the outside of the sheath, which increase the surface area and improve heat transfer efficiency. Finned tubular heaters are commonly used in heating systems for buildings, ovens, and dryers.

Immersion heaters are the most commonly used type of tubular heaters. They are designed to heat liquids such as water, oil, and chemicals, and are typically installed directly into the tank or vessel. Immersion heaters can be designed for various shapes and sizes, such as flanged, threaded, and over-the-side. They are used in industries such as food and beverage, oil and gas, and chemical processing.

Industrial flanged immersion heaters are designed to be bolted directly onto a tank or vessel for heating liquids and gases. They consist of a tubular heating element mounted inside a flange, which is then bolted to the tank or vessel. Flange heaters are commonly used in industries such as petrochemical, water treatment, and food processing.

Circulation heaters are designed to heat liquids such as water and oil that are being circulated through a system. These heaters typically consist of a tubular heating element mounted inside a vessel, with inlet and outlet ports for the fluid. Circulation heaters are commonly used in heating systems for industrial processes and in the oil and gas industry.

Duct heaters are designed for heating air or gases flowing through a duct system. They consist of a tubular heating element mounted inside a duct or a plenum, with a control panel for regulating the temperature. Duct heaters are commonly used in HVAC systems for commercial and industrial buildings.

Tubular heaters are available in different types, each with its unique features and applications. The selection of the appropriate type of tubular heater depends on the application's heating requirements, such as the type of fluid or gas being heated, the temperature range, and the desired heating capacity. Understanding the different types of tubular heaters can help in selecting the right heater for specific industrial applications.
