Immersion heaters are commonly installed inside industrial processing equipments such as liquid tanks, process pipes, pressurized vessels, etc. They are mainly used for direct heating of various industrial mediums such as water, oil, highly viscous liquid, hazardous chemicals, processing gas and many other industrial applications. An immersion heater can also operate in different environments with consistent performance, whether it is used under a pure water tank or under corrosive medium.
Electric immersion heaters are typically used to instantly starting to heat a fluid and to maintain the pre-set temperature around the immersed area of equipment, such as a liquid containing vessel. Once the heater initializes, the convection current is established and the heat will gradually spread in uniform direction around the medium until the heat transfer reaches to the top of the equipment.
Each immersion heater is designed to heat up any type of fluid and it can be customized, at cost effective prices, in order to meet specific industrial requirements. The assortment of immersion heaters is the key reason for its wide industrial usage in addition to its efficient performance, durability and low cost maintenance. The available standard heater selections include flange, screw plug, circulation and Over the Side design.
Our immersion heater is designed with the consideration of our customer’s desired environment. Based on the heater application, the following criteria are considered for every customized immersion heater: the watt density, sheath medium, immersion length, bundle diameter, environment temperature/pressure and terminal enclosure NEMA type.
An immersion heater typically composes of a metallic mounting base welded with flat or tubular electric heaters. Each tubular heater is encased with a high quality Nickel chromium resistance wire that is compressed with the electric insulator Magnesium Oxide for rapid heat transfer and protection against corrosion and external shock. In order to provide efficient heating controls, all of our immersion heaters possess a build-in adjustable temperature controller for all standard and customized designs.
The most commonly used portable industrial heaters are the flanged heaters. They are mainly used to heat up volumes of liquid and to maintain a fixed liquid or gas temperature. This type of electric heater is not limited only for industrial use such as oil heating systems, but it can also be used in residential application such as the water temperature control. This type of immersion heater generally consists of a bundle of electric heating elements tig-welded on a steel flange. In addition, a thermostat control and temperature sensors can be installed to our flanged immersion heaters in order to maintain a stable heat control. Special housing for the flange (with different terminal enclosures to choose from) can also be installed in order to protect from moisture and explosion damage.
Our basic flanged heater models are designed to suit common industrial applications such as oil and water heating. For any inquiries or recommendations for the selection of our electric heaters, feel free to contact us for assistance.
