In most parts of India, we face harsh winters, where water becomes so cold that it isn’t feasible for bathing. While geysers are a popular choice used by homes, hotels and restaurants for heating water, its application is limited. Whether you get an instant or storage geyser, it heats up water in limited capacity, takes up considerable space and the hard water deposits in the tank reduces heating efficiency, which increases overall bills. No portability is another issue. Besides, its power consumption requirement increases multifold as the scale of application increases. Though, if you choose from reliable Immersion Heater Manufacturers, you get an efficient, portable, easy to use and quick heating solution. Amongst these, the flanged immersion heater is the most versatile as its application ranges from domestic use to industrial heating. In this comprehensive blog, we will enlighten you about the working of a flanged immersion heater, its applications and which is apt for your specific needs.
How Immersion Heater Works
Flanged immersion heater can be considered an engineering marvel, as it is uncomplicated equipment, easy to carry and lightweight, but can operate at extreme temperatures up to 870°C. It works by simply immersing the heater into the tank or vessel containing the or gas intended to be heated. It works on the principle of resistance heating, in which current is passed through a resistant coil which converts electrical energy into heat, thereby increasing the surrounding temperature. Through conduction and convection this heat is transferred directly to the surrounding. The heating element is protected with sheath for maintaining separation between surrounding and the conductive coil within. It prevents the current from leaking into the liquid or surrounding air. Immersion Heater Manufacturers take meticulous care of insulation, efficiency and performance so that the users can operate these heaters at high temperature without worrying about accidents and excessive electricity bills. Apart from operating temperature, watt density of immersion heater is vital property, which gives its measurement of how much heat flux emanates per unit area.
Applications of Flanged Immersion Heater
Depending upon the operating temperature, flanged immersion heaters are used in light duty daily domestic activities like water heating for emergency backup, daily use activities; as well as in industries for food processing, sterilization of container, gas heating, oil and chemical solvents. Here’s a brief list of uses of immersion heaters according to the scale of applications:
- Domestic Use: Used for quick heating of water for bathing, cleaning utensils and clothes. The operating temperature ranges between 60-100°C which is sufficient for domestic application. The heating element can be nichrome and most common sheath material for these application is stainless steel. Ideal watt density ranges between 40 to 60 W/in².
- Industrial Use: For industrial use, the Immersion Heater Manufacturers use advanced sheath material and coils of high watt density to be able to operate efficiently for heavy duty purpose. Flanged immersion heater is used for heating cooking oils, pasteurization, sterilization, chemical heating in reactors, crude oil in storage tanks, and wastewater treatment also. Its operating temperature ranges between 600-900°C, and INCOLOY or 304 stainless steel is used for sheathing.
Conclusion
So, which flange immersion heater is best suited for your needs? Hopefully this blog should answer your query. When selecting the Immersion Heater Manufacturers, verify their safety measures by looking for BIS certifications like IS 302. We recommend you choose Hindon Electrical as they provide multiple variants for industrial heating applications with advanced features like thermostat for temperature control and proper flange assembly for easy installation in the industrial tanks or vessel.
