screw immersion heater

A screw immersion heater is a device that heats liquids or gases by direct immersion. Its core is a curved tubular heating element that threads into a threaded hole in the container. This heater offers high efficiency and power density, making it suitable for heating media such as water, oil, and chemicals. Key features include direct heating, efficient heat transfer, easy installation and maintenance, and customizable power and material options.

Working Principle

1. Heating Element
This element is typically made of a high-temperature-resistant alloy heating wire, which is brazed or welded into a metal sheath to form the heating core.
2. Sheath
This is a seamless steel or stainless steel tube that protects the heating element and insulates the heated medium.
3. Threaded Connection
The heating element is bent into a hairpin shape and welded or brazed to a threaded connection, allowing it to be screwed directly into the threaded hole of the container.
4. Heat Conduction
When energized, the heating element generates heat that is transferred directly to the immersed liquid or gas through the sheath, achieving efficient heating.

Product Advantages

1. High efficiency: All heat is directly used to heat the medium, resulting in very low energy consumption.
2. Easy to install and maintain. The threaded design makes installation simple and convenient, and the heating element can be replaced without draining the medium in the container.
3. Compact size and high power density provide sufficient heating power in limited spaces.
4. Widely applicable, suitable for heating a variety of liquids and gases, including water, oil, and heat transfer solutions.
