An immersion heater is a mechanism that is installed in a container or tank to heat a fluid. The installation can be over-the-side, threaded or flanged.
What is an Immersion Heater?
An immersion heater is a high-speed, cost-effective, and effective method for heating fluids in tanks or other equipment. Also Known as bayonet heaters, they have heating components that can insert directly into the water, oil, or other material containers to heat the whole contents.
By using the heat transfer directly for an immersion heater, liquids quickly attain the aspired temperature. Constructed of bundles of tubing, it can be mounted on the surface of a container or sunk in the contents. Their heating coils convey heat to the contents, which radiates throughout the vessel.
Immersion heaters are a cost-effective and ecologically stable procedure of heating material and generate a clean energy source without leaving the leftover discharge of pollutants. In nuclear reactors, the use of an immersion heater keeps water warm at a constant temperature for producing or generating fumes.
There are two types of immersion heaters direct and indirect immersion heaters. Direct immersion heaters have heating elements installed directly in the fluid. Indirect immersion heaters use diffusion or convection. Over the side and inline heaters are direct because their encompassing heating elements contact the fluid. Pipe and infrared immersion heaters are categorise as indirect and do not directly touch a fluid.
Types of immersion heaters
Over the side immersion heaters
The Side Immersion heaters, each offering various types of heat delivery. One type of heater has two tanks, providing 360-degree heat across both sides. This type of unit has separate tanks for hot and cold water delivery. Other types of over-side immersion heaters include single tank, dual-tank, and the newest, which has a triple-fuel tank that offers a 360 degree “hot spot” that heats three times faster than a traditional barbeque grill.
Some over the counter heaters offer a choice of single-burner, double-burner, or triple-burner units, each providing a different heat level. Single-burner units produce a steady level of heat and usually are suitable for small barbeque grills. Double-burner units have an intense burst of heat, sometimes reaching a maximum temperature of 720 degrees Fahrenheit. Triple-burner units, the latest technology, allow for precise temperatures of up to 925 degrees Fahrenheit.
Screw plug immersion heaters
Screw plug immersion heaters can provide a very efficient method for heating appliances. These devices are design for use with oil, gas or propane heaters and deliver an intense level of heat within a relatively short period of time. They are also familiar as hot stone or iceboxes and may be use in outdoor applications such as patios, decks, and poolside cabins. Most units are portable, and some are small enough to fit into a pocket or purse. Most models produce up to five gallons of steam and are of one piece of steel construction. Sizes of screw plug immersion heaters come in both large and small sizes, with one, three, and five-gallon tanks available.
A variety of processes use immersion heaters for fluid heating. These heaters are perfect for process water heating and freeze shields. All kinds of oils and heat transfer solutions can also heat using these small, efficiently controlled units. The direct immersion system is energy-saving and well accommodated for many applications.
