Introduction

Screw plug heaters are widely recognized within the industrial heating sector for their versatility and diverse applicability across numerous industries. These compact devices have revolutionized the way industries generate and manage heat, from precise temperature control in chemical processes to efficient water heating in commercial settings. Let’s delve into the world of screw plug heaters, exploring their versatility, applications, and why manufacturers like Marathon Heater are the top choice for many industrial needs.

Understanding Screw Plug Heaters

Screw plug heaters are compact heating elements designed for efficient heat transfer in liquids and gases. Their simple yet robust design allows for easy installation and precise temperature regulation, making them ideal for various industrial processes. With materials resistant to corrosion and high temperatures, screw plug heaters ensure longevity and reliability in demanding environments.

Screw Plug Immersion Heaters consist of hairpin tubular elements welded or brazed into a screw plug and provided with terminal enclosures for electrical connections. They can be screwed through a threaded opening into a tank wall or vessel. Welding or brazing depends upon the element sheath and plug material compatibility. Depending upon the customer requirement, thermowells, thermostats, or control panels can be used with these heaters to meet the objective of precise temperature control.

Screw Plug Heaters feature a smaller version of Immersion Heaters, replacing the heater flange with a threaded plug.

The different sheath materials used in these heaters have different watt densities and operating temperatures. When choosing the sheath material, consider the following points:

Stainless Steel: The maximum operating temperature is 1200°F, while the maximum watt density is 120 W/in².

Steel: The maximum operating temperature is 750°F, while the maximum watt density is 120 W/in².

INCOLOY: The maximum operating temperature is 1600°F, while the maximum watt density is 120 W/in².
