Flanged Immersion Heaters Structure
Flanged immersion heaters are composed of several key components engineered to meet specific operating conditions, ensuring efficient and reliable heating for industrial applications. Below is a detailed breakdown of their structure and features:
Heating Elements
- The heater consists of multiple electric heating elements, typically in a hairpin shape, either brazed or TIG welded for durability.
- The watt density (W/cm²) is carefully selected to match the application’s operating conditions and liquid medium.
- Materials for the heating tubes include stainless steel (AISI 321, AISI 316L, AISI 309) and high-performance alloys such as Incoloy 800/825 or Inconel 600, chosen based on environmental factors and temperature requirements.
Flange Design
- Flanges are manufactured to conform to various standards, including DIN, ASA, or custom specifications.
- The flange dimensions are calculated based on the required pressure and operating temperature, with sizes ranging from DN80 PN10 (3″ 150 lbs) to DN2500 PN250 (100″ 1500 lbs).
- The sealing system, whether single elastomeric (SEM) or double elastomeric (DEM), is chosen to ensure a reliable and leak-proof connection.
Electrical Connection Box
- Made from protected steel or stainless steel, the connection box houses the electrical terminals.
- Cable entries are sized to accommodate the number and power of the heating elements, with optional integration of a temperature control system for precise regulation.
- For operating temperatures above 110°C, an offset connection box is used to maintain junction box temperatures below 80°C for added safety.
Heating Bundle Dimensions
- The heating bundle consists of a specified immersion length and a diameter determined by the number of heating elements and the welding configuration.
- The total power output and maximum watt density (W/cm²) dictate the number and arrangement of heating elements.

- Ceramic: Great for energy-efficient heating with stable temperature control.
- Copper: Good for applications needing quick heat-up times but may require extra care to prevent corrosion.
4. Compatibility
- Ensure that the heating element is compatible with your coffee machine’s thermostatic controls or external temperature regulators for accurate performance.
5. Durability and Maintenance
- Look for corrosion-resistant materials such as stainless steel, Incoloy, or ceramic for long-lasting performance and minimal maintenance.
1. Preparation
- Power Off: Before starting the installation, ensure that the coffee machine is completely powered off and unplugged to avoid any electrical hazards.
- Required Tools: Have tools such as a wrench, screwdriver, and multimeter ready for installation.
2. Choose a Location for the Heater
- For immersion heaters, ensure the heater is properly submerged in the liquid, while tubular heaters should be installed in a dedicated tank or chamber designed for heating.
- For flexible and band heaters, ensure the heating element is wrapped securely around the boiler or tank, with even contact to ensure efficient heating.
3. Install the Heater
- Immersion Heater: Insert the heater directly into the liquid tank. Secure the heater in place, ensuring that it is fully submerged and stable.
- Tubular Heater: Mount the heater to the designated place in your coffee machine, ensuring all connections are tight and secure.
- Band Heater: Wrap the heater around the cylindrical tank and tighten it using the appropriate fasteners.
- Flexible Heater: Attach the flexible heater to the machine, ensuring it is wrapped snugly around the surface and securely held.
- Cartridge Heater: Insert the heater into the designated port or housing, ensuring it fits snugly and doesn’t interfere with other components.
4. Electrical Connections
- Ensure that the heater is correctly wired to the power source and thermostat, following the manufacturer’s instructions for electrical connections.
- Double-check the voltage and wattage specifications to avoid overheating or damaging the unit.
5. Testing the Heater
- Once the heater is installed, perform a quick test to ensure the unit is heating properly. Turn on the coffee machine and monitor the temperature to ensure proper function.
- Use a multimeter to check for continuity and ensure the heating element is correctly installed and functional.
6. Safety Checks
- Check for any visible signs of leaks, wiring issues, or overheating during the initial test.
- Confirm that all components are securely fastened and that the machine is safe to operate.
7. Regular Maintenance
- Periodically inspect the heating element for any wear and tear, and clean it as necessary to prevent build-up or corrosion.
- Regularly check for any signs of malfunction and replace the heating element if needed.
