Features & Benefits

N/A

  • Effective & efficient thermal heating
  • Can be used in air or water
  • High durability; able to withstand high temperatures (up to 1200ºC when heating in a dry condition)
  • Very good insulation characteristic; electric leakage is <10mA even when broken
  • High withstanding voltage; will not break even when 2500V is applied for 1 minute
  • High watt density; in water <70W/cm2, in air <25W/cm2
  • Corrosion resistance to aggressive fluids like acid and bases
  • Very low to no buildup of water heater scale deposits
  • Quick heat transmission. Air heating surface temperature can reach 1200ºC in 40 seconds; water heating can reach 98% thermal efficiency.
  • Small yet high powered; high design flexibility
  • High safety characteristics
  • Long service life

    Additional Information

    N/A Ultra-High Temperature Ceramic Heaters have similar characteristic to PTC heaters. As the Power (W) of the heater will vary depending on the heat dissipation rate, the Rated Power (W) specified in the the product tables is for reference only and will vary with different applications and ambient environments.

    Installation Guide

    		 N/A ULTRA-HIGH TEMPERATURE CERAMIC IMMERSION HEATERS CAN BE USED BOTH IN AIR OR UNDER WATER. WHEN USED IN AIR, THE MAXIMUM POWER IS 600W. POWER ABOVE 600W CAN ONLY BE USED IN WATER WITH THE FOLLOWING GUIDELINES WHICH MUST BE FOLLOWED:
    • Ensure heating element is entirely immersed in liquid. If partially exposed in air, it will cause breakage.
    • When water has evaporated (dry heating), please do not add water immediately. This may cause cracks or damage to the product.
    • Ensure that no glue is adhered to the surface of the product.
    • Make sure that the correct voltage is applied.
    • Ensure that the heating element is installed vertically. To ensure that the performance and reliability of the heating element is maximized, install the heating element vertically at the bottom of the container if used in an instant water heater application. The hot water outlet should be located at the top of the container. Ensure that the water level is 30~40mm above the heating element.
    • To prevent decrease of withstanding voltage of the heating element under severe ambient conditions, add a thermal resistance rubber seal to the exposed section of the heating element.
