Immersion Heaters

Flanged immersion heaters are one of the most widely used methods designed for use in tanks and pressurized vessels for heating liquids (such as water, oil, heat transfer fluid and corrosive solutions).

Flanged immersion heaters consist of hairpin bent tubular elements welded or brazed into a flange and provided with wiring boxes for electrical connections. Flange heaters are installed by bolting to a matching flange welded to the tank wall or nozzle. A wide selection of flange sizes, kilowatt ratings, voltages, terminal housings and sheath materials make these heaters ideal for all types of heating applications.

The primary objective of a flanged immersion heater design is to optimize performance, extending application's lifespan while minimizing overall lifecycle cost. These heaters are engineered for easy installation, and low maintenance, ensuring continuous heat delivery across various applications. Flange immersion heaters are typically inserted horizontally into tanks or vessels, to enable direct and efficient liquid heating, rapidly achieving the desired temperature and delivering high-performance results. Ideal for large-volume, high-power, and high-pressure applications, as well as smaller equipment like boilers and chillers, flange immersion heaters offer a reliable and economical heating solution.

Flange Immersion Heaters can be customized to meet specific requirements with variable element lengths, wattages, and voltages. Our heaters feature high-purity compacted MgO powder, ensuring exceptional heat conductivity and optimal dielectric strength. To maintain MgO density, bends are recompacted during the manufacturing process. For added temperature control, thermocouples can be installed to monitor high-limit temperatures. Spacers are strategically placed on elements to facilitate even flow distribution. Terminations are made easy with #10-32 screw terminals, and a fixed conduit support bracket keeps the supply conduit secure, even when the cover is removed.

Material Sheath Selection

Clean water, freeze protection, hot water storage, boiler and water heaters, cooling towers, heating of solutions not corrosive to copper.

Asphalt, wax, paraffin, tar, fluid heat transfer mediums, petroleum, degreasing and solvent oils, fuel oils, machine oils, alcohol.

Process water, soap and detergent solutions, soluble cutting oils, demineralized or deionized water (passivation recommended).

Solution water, corrosive solutions, air, gas, steam super heating Be certain that the sheath material and watt density selected are compatible with the material being heated and the operating temperature.

Standard Element Sheath Materials

A Nickel (30-35%), Chromium (19-23%), Iron alloy. The high nickel content of this alloy contributes to its resistance to scaling and corrosion. Used in air heating (also see Incoloy 840) and immersion heating of potable water and other liquids that are not corrosive to an Incoloy 800 sheath.

Applications include fluid heat transfer media, tar, high to low viscosity petroleum oils, asphalt, wax, molten salt, and other solutions not corrosive to a steel sheath.

A Chromium (16-18%), Nickel (11-14%), Iron Alloy with Molybdenum (2-3%) added to improve corrosion resistance in certain environments, especially those that would tend to cause pitting due to the presence of chlorides. Applications include deionized water.

Mainly used in clean water heating for washrooms, showers, rinse tanks and freeze protection of storage tanks.

Optional Element Sheath Materials

A Chromium (18-20%), Nickel (8-11%), Iron Alloy used in the food industry, sterilizing solutions, air heating and many organic and inorganic chemicals.

A Chromium (17-20%), Nickel (9-13%), Iron Alloy modified with the addition of titanium to prevent carbide precipitation and the resulting intergranular corrosion that can take place in certain mediums when operating in the 800-1200°F (427-649°C) temperature range.

A Nickel (18-20%), Chromium (18-22%), Iron alloy. Incoloy 840 has about 10% less nickel than Incoloy 800. Used in many air heating applications where it has exhibited superior oxidation resistance at less cost than Incoloy 800.

A Nickel (38-46%), Chromium (19.5-23.5%), Molybdenum (2-3%) Iron alloy.

Magnesium in Water as Sacrificial Anodes

Sacrificial anode is a piece of metal that is more reactive than the metal it is protecting. It is designed to corrode in place of the protected metal, sacrificing itself to protect the less reactive metal from corrosion.

Sacrificial anodes are commonly used in:

• Water Heaters
• Boilers
• Pipelines
• Ship Hulls
• Storage Tanks

Magnesium (Mg) is electrochemically the most active metal employed in common structural alloys of steel, iron and aluminium. Magnesium is widely used as a Sacrificial Anode, so as to provide Cathodic Protection to underground and undersea metallic structures, ships, submarines, bridges, decks, aircraft and ground transportation systems.

Magnesium Anodes are manufactured in a comprehensive range of shapes and sizes. The main benefit of using a magnesium anode rod in water tank is that it protects the inner lining of the water heater tank from rust and corrosion. This can significantly increase the lifespan of the tank and prevent leaks.

Benefits of Magnesium Sacrificial Anodes

• Highly effective at protecting metals from corrosion.
• Economical solution.
• Simple installation and maintenance.

Software Human Machine Interface (HMI) Functions

Human-Machine Interface (HMI) is a user interface that allows a human operator to monitor and control processes in hot water calorifier system such as to automate water flow and stop pumps when water is not in need.

HMI can be a graphical user interfaces (GUIs) on a computer, allow human interface with touchscreens, or physical control panels with buttons during emergencies. They work with onboard actuators and instruments to perform operations & maintenance monitoring, and feedback for alarm and faults.

Advantages of Human-Machine Interface

• Improved Efficiency of the process being controlled.
• Increased Safety by allowing time for corrective action to potential problems.
• Cyber security with usage monitoring and hacking preventions.
• Enable Remote Monitoring and Control.
• Applicable in Safe and hazardous locations.

HMI is typically connected to a Programmable Logic Controller (PLC), which is responsible for controlling the process based on input from the HMI and sensors in the field. The HMI simply presents information to the operator and allows them to input commands, which are then sent by fiber optics cable to the PLC to be implemented.

Programmable Logic Controller (PLC) is a specialized computer interface configuring communication protocols, establishing hardware connections and provide user-friendly interface for operators to interact with the operated system in industrial automation. EX PLCs are designed to endure explosive environments. PLCs are widely used because they are reliable, flexible, and can be reprogrammed for different tasks and so reducing the need for rewiring. PLCs are capable of real-time processing, ensuring immediate response to input conditions.

Mowe sit our HMI on robust and reliable software platforms proven in Marine & Offshore from Siemens or Rockwell Allen Bradley.

Fiber Optics Cables are used in data transmission and communication system as they serve several critical functions:

• High-speed data transmission.
• Long-distance communication transmission without significant loss.
• Immune to electromagnetic interference.
• Offers a much higher bandwidth compared to copper cables.
• Provides data transmission security.
• Supports various network topologies such as line, star, and ring, providing flexibility in network design and implementation.
