Applications

High Temperature Immersion Heaters

Ultra-High Temperature Ceramic Water Heating Elements can be adapted in a vast range of applications for both industrial and commercial uses. Ultra-High Temperature Ceramic Water Heating Elements is suitable for all kinds of electric water heaters, liquid heaters, air conditioners, ignition device, instance hot water taps, steam generators and many more.

High thermal conductivity of the Ultra-High Temperature Ceramic Water Heating Elements is much more efficient than other heating elements, both metallic and non-metallic materials. Under the same ambient environment and power, Ultra-High Temperature Ceramic Water Heating Elements is only 1/8~1/3 the size of other heating elements. It is light, small and can easily be implemented into small appliances.

Due to its unique high temperature features, Ultra-High Temperature Ceramic Water Heating Elements can be effectively utilized in heating liquid/water. Current immersion heaters (water heating elements) on the market have several disadvantages in their applications. They usually encounter problems such as quick buildup of water heater scales; crack and break easily causing electric leakage and short product lifetime. The new revolutionary Ultra-High Temperature Ceramic Water Heating Elements easily overcome these risks. Its innovative design can easily help you resolve these design issues.

Application benefits

  1. When used as immersion heater, it will not oxidize or cause electric leakage.
  2. Do not have to worry about gas pollution or related safety hazards.
  3. Does not cause buildup of scale deposits, longer product lifetime.
  4. Will not self burst causing cracks in water pipes.
  5. High heating efficiency, does not require preheating.
  6. Small and compact, does not take up much space, suitable for use in lightweight electric products.
  7. Strong corrosion resistance (10 times more than stainless steel).
  8. Able to endure high temperature.

Installation Guidance: When heating liquid/water

  1. Please ensure heating element is entirely immersed in liquid. If partially exposed in air will cause breakage.
  2. When water has evaporated (dry heating), please do not add water immediately. May cause cracks or damage to product.
  3.  Ensure there are not glue adhered to the surface of the product.
  4. Make sure correct voltage is applied.
  5. Ensure the heating element is installed vertically. To ensure the performance and reliability of our heating element is maximized, it is recommended to install the heating element vertically at the bottom of the container if used in the instant water heater application. The hot water outlet should be located at the top of the container and ensure water level is 30~40mm above the heating element.
  6. To prevent decrease of withstanding voltage of the heating element under server ambient condition. It is recommended to add thermal resistance rubber seal to the exposed section of the heating element.
