Frequently Asked Questions (FAQs)
1. What is an Immersion Tubular Heater?
An Immersion Tubular Heater is an electric heating element designed to be directly immersed in liquids such as water, oil, or chemicals to heat them efficiently. It is commonly used in industrial and commercial heating applications.
2. How does an Immersion Tubular Heater work?
It works by passing electric current through a resistance wire inside the tube. The heat generated is transferred through the metal sheath directly into the liquid, ensuring fast and uniform heating.
3. What are Immersion Tubular Heaters used for?
They are widely used in:
-
Water heating tanks
-
Oil and chemical processing
-
Boilers and storage vessels
-
Food and beverage industries
-
Pharmaceutical and industrial applications
4. What materials are used in Immersion Tubular Heaters?
Typical materials include:
-
Stainless steel, copper, or Incoloy sheath
-
Nickel-chromium (NiCr) heating wire
-
Magnesium oxide insulation
These materials ensure durability, corrosion resistance, and efficient heat transfer.
5. What is the operating temperature range?
Immersion Tubular Heaters can operate at temperatures up to 750°C, depending on the material, design, and application.
