An immersion heater is a rapid, economically viable, and highly effective means to heat liquids in tanks, vats, or devices. These heaters have heating components that can be put directly into a container of water, oil, or other material to heat the entire contents.
The direct heat transfer of this type of heater allows liquids to achieve the desired temperature rapidly. Heaters, which are made of tubing bundles, can be fixed on the side of a container or submerged in its contents. Their heating coils deliver heat to the contents of the container, which are distributed throughout the container.
Working Process of Immersion Heater
These heaters have an electrically resistant heating element encased in a sheath. When the heating element is turned on, it heats its enclosing jacket, which in turn heats the sheath, which in turn heats the liquid. The conductivity of the jacket and sheath determines its effectiveness. There are two immersion heaters direct and indirect that heat liquids in different ways.
Direct immersion
It is put directly into the liquid at the top or through a side fitting. Its heating element comes into touch with the to-be-heated fluid. When it’s in place, it’s turned on, and electricity flows through the heating element into the liquid.
Indirect immersion
It is immersed in liquid after being placed into a pipe with a closed end. The heating element heats the air within the pipe, resulting in an oven effect that heats the liquid. An indirect immersion has the advantage and purpose of not coming into direct contact with the fluid, which prevents contamination and corrosion.
Moreover, the time required to heat a substance is determined by the quantity and power level of the heater. They are intended to heat specific sorts of materials.
Immersion Heater Components
Certain aspects must be closely examined when inspecting this heater. They are:
- Sheath material
- Power density
- Wattage
- Enclosure
- Temperature scale
- The heating element
Foremost Types of Bayonet Heaters
These heaters are further classified as direct or indirect based on how they are placed into the substance to be heated. Nevertheless, it is impossible to include all types since the list is so long, and new ones are being introduced by Immersion Heater Manufacturers in India. Some of the most common types are as follows:
Pipe Plug Heaters:
These heaters are intended for small to medium-sized containers with pressure ratings of up to 3000 pounds per square inch. They screw directly into a tank wall aperture and can be sheathed in copper, stainless steel, Incoloy, or steel. The material they will heat is determined by the type of sheath used.
Quartz Immersion Heaters:
These are designed for plating and acid-finishing solutions, except for solutions containing hydrofluoric or fluorides. They can survive pH ranges ranging from 0 to 9 and are resistant to sulfuric and hydrochloric acids.
Circulation Heaters:
These heaters can be used for water heating, freeze prevention, heat transfer for oil, fuel oil heating, steam, air, gas heating, etc. They are intended to heat a flowing liquid through inline or side pipes. The heating element, heating chamber, sensor or thermostat, jacket, insulation, and inlet/outlet connections are all incorporated into units.
To Finish
When selecting an immersion heater, it is critical to select one that is built for the material to be heated, as not all variations are suitable for all solutions, fluids, or materials.
